Abstract
INTRODUCTION COVID-19 is characterized by a varied clinical course. The aim of the work was to identify associations of SNPs of hemostatic system genes with COVID-19. MATERIALS AND METHODS DNA was isolated from patients (n=117) and healthy participants (n=104). All infected patients were divided into 3 groups, depending on disease severity assessment, which was appreciated by NEWS2. Another group consisted of participants, who had asymptomatic infection in the past. Determination of SNPs of the genes FGB (-455 G/A), FII (20210 G/A), FV (1691 G/A), FVII (10976 G/A), FXIIIA1 (103 G/T), ITGA2 (807 C/T), ITGB3 (1565 T/C), SERPINE1 (-675 5G/4G) were performed by PCR using the "Genetics of Hemostasis" kit ("DNA-Technology", Russia). RESULTS In analyzed SNPs, no significant differences were detected between the group of infected patients and healthy participants. But significant association was revealed in gene SERPINE1 (-675 5G/4G), when patient groups, differing in the disease severity, were analyzed relative to the group of participants with asymptomatic infection (p=0.0381; p=0 .0066; p=0.0009). It was found, that as COVID-19 severity scores increased, the proportion of 5G allele of gene SERPINE1 decreased, and the proportion of the 4G allele increased (p=0.005; p=0.009; p=0.0005). Similar processes were observed for genotypes 5G/5G and 4G/4G. DISCUSSION The gene SERPINE1 (-675 5G/4G) is associated with the severity of COVID-19. CONCLUSION For the first time, it was discovered that 5G/5G genotype of gene SERPINE1 (-675 5G/4G) can be a marker of a milder course of COVID-19, and the 4G/4G genotype as a more severe one.

Abstract
INTRODUCTION The study of the mechanisms of transmission of the SARS-CoV-2 virus is the basis for building a strategy for anti-epidemic measures in the context of the COVID-19 pandemic. Understanding in what time frame a patient can spread SARS-CoV-2 is just as important as knowing the transmission mechanisms themselves. This information is necessary to develop effective measures to prevent infection by breaking the chains of transmission of the virus. The aim of the work is to identify the infectious SARS-CoV-2 virus in patient samples in the course of the disease and to determine the duration of virus shedding in patients with varying severity of COVID-19. MATERIALS AND METHODS In patients included in the study, biomaterial (nasopharyngeal swabs) was subjected to analysis by quantitative RT-PCR and virological determination of infectivity of the virus. RESULTS We have determined the timeframe of maintaining the infectivity of the virus in patients hospitalized with severe and moderate COVID-19. Based on the results of the study, we made an analysis of the relationship between the amount of detected SARS-CoV-2 RNA and the infectivity of the virus in vitro in patients with COVID-19. The median time of the infectious virus shedding was 8 days. In addition, a comparative analysis of different protocols for the detection of the viral RNA in relation to the identification of the infectious virus was carried out. CONCLUSION The obtained data make it possible to assess the dynamics of SARS-CoV-2 detection and viral load in patients with COVID-19 and indicate the significance of these parameters for the subsequent spread of the virus and the organization of preventive measures.

Abstract
SARS-CoV-2 specific antibody response is a generally accepted measure of postinfection and vaccination-induced immunity assessment. The dynamics of avidity maturation and neutralizing activity of virus-specific immunoglobulins G during the SARS-CoV-2–associated coronavirus infection was studied in cohorts of vaccinated volunteers and COVID-19 patients. 4–6 months after vaccination, neutralization activity was low compared to hospitalized patients (medians 57.4% vs 86.4%). On the opposite, the avidity indices in vaccinated volunteers were significantly higher (median 76.7%) than among hospitalized patients (median 61.4%). During the acute phase of the disease (14–16 days PI), post-vaccination patients have also higher avidity indices than primary patients (medians 43.5% vs 20.4%). Our results suggest that in long-term perspective antibody affinity maturation rate is higher after vaccination than after a natural infection. We demonstrated that Sputnik V vaccination leads to formation of high-avidity IgG, which persists for at least 6 months of observation. These results also indicate the presence of protective efficacy markers for at least 4–6 months after the vaccination or a previous illness and gives grounds for the half-year time period chosen for booster immunization with Sputnik V in Russia.

Abstract
The COVID-19-associated mortality remains high. Studying the features of the COVID-19 course in vaccinated patients, who have got ill on different dates after vaccination, compared to unvaccinated individuals is relevant. The study was aimed to assess clinical and immunological features of the COVID-19 course, as well as to assess humoral immunity (virus neutralizing activity, VNA) and SARS-CoV-2 S protein RBD domain variation in the groups of patients, previously vaccinated with Sputnik V, and unvaccinated patients. A total of 251 patients with confirmed diagnosis of COVID-19 were enrolled, of them 116 individuals were previously vaccinated with one or two Sputnik V vaccine components, and 135 patients were not vaccinated (comparison group). Individuals over 50 years of age prevailed (82.8%). The patients, who received two vaccine components, had mild to moderate COVID-19 (92.1%). In the group of unvaccinated patients, 11 individuals received treatment in the ICU, 10 of them died. The viral load was significantly lower in vaccinated patients. Mutations of SARS-CoV-2, such as S477N, S477N+A522S, E484K and E484K+S494P, were identified both in vaccinated and unvaccinated patients. Assessment of the neutralizing activity of sera revealed no significant differences in VNA against different variants of SARS-CoV-2 mutations. The data obtained demonstrate that the lack of vaccination is an aggravating factor and is capable of increasing the risk of severe course and death in patients with COVID-19.

Abstract
INTRODUCTION The surveillance of influenza viruses in ARVI structure and study of their properties in epidemic season 2019-2020 in Russian Federation are actual for investigations due to tasks of Global Influenza Strategy initiated by WHO in 2019. MATERIAL AND METHODS The data of epidemiological surveillance on influenza- and ARVI-associated morbidity and hospitalization in different age groups of population were analyzed; virological, genetic and statistical methods were used. RESULTS Preschool children were involved in epidemic the most. Meanwhile, the highest rate of hospitalization was observed in patients of 18-40 years old. Influenza A(H1N1)pdm09 virus dominated in etiology of ARVI in hospitalized patients and pneumonia. The role of respiratory viruses in severe cases of pneumonia and bronchoalveolar syndrome in children was shown. The differences in spectrum of circulating viruses caused ARVI in different regions of Russia were found. Influenza A(H1N1)pdm09 and B/Victoria-like viruses were the main etiological agents that caused of epidemic; its activity among all ARVI was 7.3 and 8.0%, respectively. The differences in antigenic properties of influenza A(H3N2) and B epidemic strains compared to vaccine viruses were found. The populations of epidemic strains were presented by following dominant genetic groups: 6B1.A5/183P for A(H1N1)pdm09, 3С.2а1b+137F for A(H3N2) and V1A.3 line B/Victoria-like for B viruses. The good profile of epidemic strains susceptibility to anti-neuraminidase inhibitors has been saved. The most of the studied influenza strains had the receptor specificity characteristic of human influenza viruses. CONCLUSIONS Obtained results identified the peculiarities of viruses caused the influenza and ARVI in epidemic season 2019-2020 in different regions of Russia. These results suggested the important role of influenza A(H1N1) pdm09 in severe cases and pneumonia in adults 18-40 years old. The continuing drift in influenza viruses was found, which, apparently, could not but affect the efficacy of vaccine prophylaxis and was also considered in the recommendations of WHO experts on the composition of influenza vaccines for the countries of the Northern Hemisphere in the 2020-2021 season.

Abstract
Whereas the XX century marked the history of acute respiratory disease investigation as a period for generating in-depth system of combating influenza viruses (Articulavirales: Orthomyxoviridae, Alpha-/Betainfluenzavirus) (based on environmental and virological monitoring of influenza A virus in its natural reservoir — aquatic and semi-aquatic birds — to supervising epidemic influenza), a similar system is necessary to build up in the XXI century with regard to especially dangerous betacoronaviruses (Nidovirales: Coronaviridae, Betacoronavirus): Severe acute respiratory syndrome-related coronavirus (SARS-CoV) (subgenus Sarbecovirus), Severe acute respiratory syndrome-related coronavirus 2 (SARSCoV-2) (Sarbecovirus), Middle East respiratory syndrome-related coronavirus (MERS-CoV) (Merbecovirus). This became particularly evident after pandemic potential has been revealed in 2020 by the SARS-CoV-2. This review provides an insight into the historic timeline of discovering this virus, its current taxonomy, ecology, virion morphology, life cycle, molecular biology, pathogenesis and clinical picture of the etiologically related COVID-19 (Coronavirus disease 2019) as well as data available in the scientific literature on the anti-SARS-CoV-2-effectiveness of passive immunotherapy and most debated drugs used to treat COVID-19: Chloroquine, Hydroxychloroquine, Nitazoxanide, Ivermectin, Lopinavir and Ritonavir, Camostat mesilate, Remdesivir, Ribavirin, Tocilizumab, Anakinra, corticosteroids, and type I interferons. The pathogenesis of SARS-CoV-2 infection implicates decreased efficacy of artificial respiration, which, in this case might be replaced by more efficient extracorporeal membrane blood oxygenation supplemented with nitrogen oxide and/or Heliox inhalations.

Abstract
Results of analysis of phylogenetic, virological, epidemiological, ecological, clinical data of COVID-19 outbreaks in Wuhan, China (PRC) in comparison with SARS-2002 and MERS-2012 outbreaks allow to conclude:– the etiological agent of COVID-19 is coronavirus (2019-CoV), phylogenetically close to the SARS-CoV, isolated from human, and SARS-related viruses isolated from bats (SARS-related bat CoV viruses). These viruses belong to the Sarbecovirus subgenus, Betacoronavirus genus, Orthocoronavirinae subfamily, Coronaviridae family (Cornidovirinea: Nidovirales). COVID-19 is a variant of SARS-2002 and is different from MERS-2012 outbreak, which were caused by coronavirus belonged to the subgenus Merbecovirus of the same genus;– according to the results of phylogenetic analysis of 35 different betacoronaviruses, isolated from human and from wild animals in 2002-2019, the natural source of COVID-19 and SARS-CoV (2002) is bats of Rhinolophus genus (Rhinolophidae) and, probably, some species of other genera. An additional reservoir of the virus could be an intermediate animal species (snakes, civet, hedgehogs, badgers, etc.) that are infected by eating of infected bats. SARS-like coronaviruses circulated in bats in the interepidemic period (2003-2019);– seasonal coronaviruses (subgenus Duvinacovirus, Alphacoronavirus) are currently circulating (November 2019– January 2020) in the European part of Russia, Urals, Siberia and the Far East of Russia, along with the influenza viruses A(H1N1)pdm09, A(H3N2), and В, as well as six other respiratory viruses (HPIV, HAdV, HRSV, HRV, HBoV, and HMPV)

Abstract
In the 2015-2016 epidemic season, there were dominant influenza A(H1N1)pdm09 strains (over 90%) among the circulating influenza viruses in most countries of the Northern Hemisphere and in Russia. A study of the antigenic properties of influenza A(H1N1)pdm09 strains revealed no differences in those of vaccine virus. Sequencing showed that there were amino acid substitutions in hemagglutinin (receptor binding and Sa sites) and in the genes encoding internal proteins (PA, NP, M1, and NS1). The rise in the incidence in the Russian Federation, which was etiologically associated with influenza viruses, was registered in January-February 2016 with its maximum being observed at 4-5 weeks of 2016. Within the framework of the epidemiological surveillance of circulating influenza viruses in the Russian Federation, which was conducted by the WHO European Office, the D.I. Ivanovsky Institute of Virology, Honorary Academician N.F. Gamaleya Federal Research Centre for Epidemiology and Microbiology, Ministry of Health of Russia, and the Research Institute of Influenza, Ministry of Health of Russia, monitored at the Infectious Diseases Hospital One (IDH-1), Moscow Healthcare Department. Among 1491 examinees, influenza was verified in 104 (21.3%) adults, 208 (42.5%) pregnant women, and 177 (36.2%) children. Influenza A(H1N1)pdm09 was more often diagnosed in the age group of 15-40 years (63.7%); the proportion of influenza patients aged over 50 years increased (22.1%). Most adult patients had moderate influenza; pneumonia complicated the disease in 27.4%. Influenza in the pregnant women was complicated by pneumonia in 4.8% of cases. Influenza was more frequently diagnosed in infants and preschool children aged 0 to 3 years (42.9%), 4 to 6 years (41.2%), and older (15.9%), namely: 7-9 years (10%) and 10-12 years (5.9%). Influenza in the children was complicated by acute tonsillitis (19.4%) and varying degrees of laryngeal stenosis (12.4%). Bronchial obstructive syndrome developed in 2.5%, the rate of pneumonia was 6.2%. Antiviral therapy (AVT) in the early stages of the disease reduces the risk of its severity, the frequency of secondary complications, and the duration and degree of clinical symptoms of influenza. AVT with oseltamivir, zanamivir, imidazolyl ethanamide pentandioic acid (ingavirin), and interferon-a2b (viferon) has been performed in the patients hospitalized at Moscow IDH-1 in the 2015-2016 epidemic season.

Abstract
The article presents the features of the influenza virus circulation for the period from October 2016 to May 2017 in some territories of Russia collaborating with the D.I. Ivanovsky Institute of Virology, Federal State Budgetary Institution "N.F. Gamaleya Federal Research Centre for Epidemiology and Microbiology", Ministry of Health of the Russian Federation. One of the 2016-2017 season's peculiarities in Russia and countries of the Northern hemisphere was the earlier start of an increase in ARD morbidity with peak indexes reached towards the end of December 2016 - January 2017. First, influenza A(H3N2) virus was predominant; then, it was followed by influenza B virus activity observed until the end of the season. The indexes of morbidity were higher than in the previous season, while the rates of hospitalization and mortality were lower, lethal cases being detected in persons 65 years old and older. Epidemic strains of influenza A(H3N2) virus belonged to 3c.2a genetic group, reference strain A/Hong Hong/4408/2014, and its subgroup 3c.2a1, reference A/Bolzano/7/2016, that are antigenically similar. Strains of influenza B virus were antigenically similar to the B/Brisbane/60/2008 vaccine virus. Strains were sensitive to oseltamivir and zanamivir. The share participation of non-influenza ARI viruses was similar to preliminary epidemic seasons. WHO has issued recommendations for influenza virus vaccines composition for 2017-2018 for the Northern hemisphere.

Abstract
The Ebola virus disease (EVD) is one of the most dangerous infections affecting humans and animals. The first EVD outbreaks occurred in 1976 in Sudan and Zaire. Since then, more than 20 outbreaks have occurred; the largest of which (2014-2016) evolved into an epidemic in West Africa and claimed the lives of more than 11,000 people. Although vaccination is the most effective way to prevent epidemics, there was no licensed vaccine for EVD at the beginning of the latest outbreak. The development of the first vaccines for EVD started in 1980 and has come a long technological way, from inactivated to genetically engineered vaccines based on recombinant viral vectors. This review focuses on virus-vectored Ebola vaccines that have demonstrated the greatest efficacy in preclinical trials and are currently under different phases of clinical trial. Particular attention is paid to the mechanisms of immune response development, which are important for protection from EVD, and the key vaccine parameters necessary for inducing long-term protective immunity against EVD.

Abstract
Serologic studies occupy a significant place in influenza diagnosis. The article presents an analysis of the developed experimental version of ELISA test-systems for the detection of specific antibodies to the virus influenza A(H1N1)pdm09, and their dynamics at different stages of infection as compared with those of the traditional HAI method. The study included 20 paired samples of serum from patients hospitalized at different stages of the disease with etiology associated with the influenza virus A(H1N1)pdm09. Two groups were formed on the basis of HAI data, which showed the presence or absence of significant growth of specific antibodies to the influenza virus A(H1N1)pdm09. The control group consisted of 20 serum samples from individuals without influenza but with chronic hepatitis C. To examine the virus specific antibody two types of ELISA test systems were used. The first system was intended for the detection of IgM to the influenza virus A(H1N1)pdm09; the second was used for revealing specific IgG. The study showed the accuracy and specificity of detectable IgM and IgG to the virus influenza A(H1N1)pdm09. The dynamics of specific IgG titers in 15 of the 20 pairs of sera was reliable. The increase in titers was more pronounced than in the HAI. IgM against influenza virus could be detected up to 10 days, although reliable dynamics of these antibodies was not detected in paired samples. The test system was specific for the determination of both IgG and IgM antibodies to the influenza virus A(H1N1)pdm09 and significantly more sensitive than HAI. Using this ELISA test system, it is possible to monitor the dynamics of IgG to this virus even in the absence of diagnostic increases in antibody titers in HAI.

Abstract
Ebola hemorrhagic fever, also known as Ebola virus disease or EVD, is one of the most dangerous viral diseases in humans and animals. In this open-label, dose-escalation clinical trial, we assessed the safety, side effects, and immunogenicity of a novel, heterologous prime-boost vaccine against Ebola, which was administered in 2 doses to 84 healthy adults of both sexes between 18 and 55 years. The vaccine consists of live-attenuated recombinant vesicular stomatitis virus (VSV) and adenovirus serotype-5 (Ad5) expressing Ebola envelope glycoprotein. The most common adverse event was pain at the injection site, although no serious adverse events were reported. The vaccine did not significantly impact blood, urine, and immune indices. Seroconversion rate was 100 %. Antigen-specific IgG geometric mean titer at day 42 was 3,277 (95 % confidence interval 2,401–4,473) in volunteers immunized at full dose. Neutralizing antibodies were detected in 93.1 % of volunteers immunized at full dose, with geometric mean titer 20. Antigen-specific response in peripheral blood mononuclear cells was also detected in 100 % of participants, as well as in CD4+ and CD8+ T cells in 82.8 % and 58.6 % of participants vaccinated at full dose, respectively. The data indicate that the vaccine is safe and induces strong humoral and cellular immune response in up to 100 % of healthy adult volunteers, and provide a rationale for testing efficacy in Phase III trials. Indeed, the strong immune response to the vaccine may elicit long-term protection. This trial was registered with grls.rosminzdrav.ru (No. 495*), and with zakupki.gov.ru (No. 0373100043215000055).

Abstract
This work describes the specific features of the influenza virus circulating in the period from October 2015 to March 2016 in 10 cities of Russia, the basic laboratories of CEEI at the D.I. Ivanovsky Institute of Virology "Federal Research Centre of Epidemilogy and Microbiology named after the honorary academician N.F. Gamaleya" of the Ministry of Health of the Russian Federation. The increase in the morbidity caused by influenza viruses was detected in January-February 2016. The duration of the morbidity peak was 4-5 weeks. The most vulnerable group included children at the age from 3 to 6; a high rate of hospitalization was also detected among people at the age of 15-64 (65%). In clinic symptoms there were middle and severe forms with high frequency of hospitalization as compared with the season of 2009-2010, but much higher in comparison with the season of 2014-2015. Some of the hospitalized patients had virus pneumonias, half of which were bilateral. Among these patients, 10% were children; 30%, adults. The mortality in the intensive care unit of the hospital was 46%. Almost all lethal cases were among unvaccinated patients in the case of late hospitalization and without early antiviral therapy. The predominance of the influenza A(H1N1)09pdm virus both in the Russian Federation and the major part of the countries in the Northern hemisphere was noted. The results of the study of the antigenic properties of influenza strains of A(H1N1)pdm09 virus did not reveal any differences with respect to the vaccine virus. The sequencing data showed the amino acid substitutions in hemagglutinin (receptor binding and Sa sites) and in genes encoding internal proteins (PA, NP, M1, NS1). Strains were sensitive to oseltamivir and zanamivir and maintained resistance to rimantadine. The participation of non-influenza ARI viruses was comparable to that in preliminary epidemic seasons.

Abstract
Survey data from autopsy specimens from patients who died from pneumonia caused by the influenza A(H1N1) pdm09 in 2012-2014 and mutant forms of influenza virus in these patients (position 222 in the receptor-binding region of hemagglutinin) were presented. In total, according to aggregate data, obtained with three different methods (sequencing, next-generation sequencing (NGS), virus isolation) mutant viruses were detected in 17 (41%) from 41 patients. The proportion of the mutant forms in viral populations ranged from 1% to 69.2%. The most frequent mixture was the wild type (D222) and mutant (D222G), with proportion of mutant type ranged from 3.3% to 69.2% in the viral population. Mutation D222N (from 1.1% to 5.5%) was found rarely. Composition of the viral population from one patient is extremely heterogeneous: in left lung there was only wild type D222, meantime in right lung - mixture of mutant forms 222D/N/G (65.4/32.5/1.1%), in trachea - mixture 222D/G/Y/A (61.8/35.6/1.2/1.4%, respectively), and in bronchi compound of 222D/G/N/A (64.3/33.7/1/1%, respectively) were detected. The obtained data indicate that the process of adaptation of the virus in the lower respiratory tract is coupled with the appearance of different virus variants with mutations in the receptor-binding region. Mutant forms of the virus are observed in the lower respiratory tract of the majority of patients with lethal viral pneumonia. However, if they are a minor part of the population, they cannot be detected by the method of conventional sequencing. They can be identified using the NGS methods.

Abstract
The goal of this work was to present the data of the study of the peculiarities of the generation factors of humoral immunity in the response to the infection with the pandemic influenza A (HIN1) pdmO9 in patients with different epidemiological anamnesis. High ability of the influenza viruses to spread over closed communities and the transfer of the maternal antibodies to babies, including a pandemic strain of the influenza virus A (H1N1) pdm09, was confirmed. The results of this study showed that the immune response to the surface antigens of the influenza virus (hemagglutinin and neuraminidase) was formed during the natural infection with the pandemic strains of the influenza A (H1N1) pdm09 in more than a half of the cases simultaneously.

Abstract
AIM To characterize the 2013-2014 epidemic season from the results of detection of influenza infection in patients; to provide the molecular genetic characteristics of the strains isolated from deceased patients. SUBJECTS AND METHODS The investigators examined 1203 patients (387 children, 509 people older than 16 years of age, 307 pregnant women) admitted to Moscow Clinical Infectious Diseases Hospital One with the clinical signs of acute respiratory viral diseases. Nasal lavage and autopsy specimens were used to isolate viral strains, then to sequence genomic fragments, and to determine receptor specificity. RESULTS Out of the 1203 examinees, 284 (23.6%) were influenza-positive: 221 (77.8%), 24 (8.5%), and 39 (13.7%) patients had influenza A(H3N2), influenza A(H1N1)pdm09, and influenza B, respectively. Influenza was notified in 42,7% of the pregnant women. There was a preponderance of its moderate form; its severe form developed in single cases having comorbidities. One fatal outcome was registered. The intake of antiviral medications in the first 48 hours of the disease could prevent complications. The investigators revealed mutations in the strain isolated from the bronchoalveolar lavage fluid of a patient with severe pneumonia complicated by acute respiratory distress syndrome. CONCLUSION There is evidence that there are mutant A(H1N1)pdm09 viruses that have high pneumotropicity. The high risk of their circulation in the population and the risk of severe influenza forms involving the lower respiratory tract remain. Early antiviral therapy in the first 36-48 hours diminishes the clinical manifestations of influenza and reduces the risk of developing complications.

Abstract
The results of the study of the autopsy materials from 61 patients with the diagnosis of pneumonia received by virological and genetic methods are reviewed. The materials were studied at the Influenza Etiology and Epidemiology Center of the Ivanovsky Institute of Virology, Ministry of Health and Social Development of the Russian Federation, during epidemic seasons 2009-2010 and 2010-2011. The data were analyzed with respect to age, sex, comorbidity diseases and identified on the groups of the risk of severe forms of the disease. The presence of the pandemic influenza virus strain RNA was confirmed in 70.5% of materials; RNA of influenza B was detected in 1.2% cases. The co-infections caused by the bocavirus, adenovirus, parainfluenza virus type 2 and 4, rhinovirus, and streptococcus were detected only in 19.7%. In most cases, the influenza virus was the etiologic agent of lethal pneumonia, which justifies the necessity of the early etiological diagnosis and treatment with antiviral drugs.

Abstract
The goal of this work was to compare the efficiency of the influenza A and B viruses Isolated during 2010-2011 epidemic season. The clinical samples were taken in the test tubes with the transport medium on the.basis of the medium EMEM and commercial test tubes Sigma-Virocult (M40 Compliant, Sigma Virocult) and Virocult (M40 Compliant, Virocult). The results of this work demonstrated higher efficiency of influenza A and B viruses isolation from nasopharyngeal swabs of the patients taken in the test tubes Sigma-Virocult (M40 Compliant, Sigma Virocult) and Virocult (M40 Compliant, Virocult) with the transport medium as compared with the efficiency of influenza strains isolation from nasopharyngeal swabs taken in test tubes with the medium EMEM with respect to all estimated indicators: efficiency of isolation, a passage of isolation and the titer of isolates. The possibility of the long-term storage of a clinical material at room temperature and at 4 degrees C was confirmed, without resorting to freezing, which is significant in the absence of the necessary equipment.

Abstract
The results of analysis of the peculiarities of the epidemic 2011-2012 development in the areas of 10 cities of Russia obtained by basic laboratories of IEES on the base of D.I. Ivanovsky Research Institute of Virology, Ministry of Public Health and Social Development of Russia, are presented. The increasing ARD morbidity caused by the influenza viruses was detected rather late--in February-March 2012. The highest indices of the morbidity were detected during weeks 10-13 followed by decreasing to threshold levels by week 27. Children 0-2 and 3-6 years old were involved the most, meantime the high rate of hospitalization was found for 15-64 years old aged group (25%). Influenza A(H3N2) and B viruses were the cause of the epidemic. The results of studies of the antigenic and genetic properties of the influenza strains showed most of them to be close relatives to the vaccine strains. Some heterogeneity of circulating strains and their drift variants were found as well. All tested strains were sensitive to arbidol, oseltamivir and zanamivir, and saved resistance to rimantadine. The ratio of ARD viruses was comparable with the last epidemic seasons.

Abstract
The emergent 2009 A(H1N1) pandemic brought into acute focus the problem of choosing the most effective anti-influenza drugs for successive influenza infection spreading control. Oseltamivir and zanamivir, influenza virus neuraminidase inhibitors (NAIs), were recommended by the WHO experts for the treatment and prevention of influenza, including that caused by pandemic strains. A major concern regarding the use of specific antiviral compounds is the emergence of the drug-resistant strains. Oseltamivir carboxylate and zanamivir IC50 values were equal to 0.3-5.2 microM for the most of A(H1N1)pdm09 pandemic strains and 1.6-8.6 microM for the strains of influenza B virus in cell-based ELISA assay (2009-2010 season). All the studied strains of influenza A(H1N1 ) pdm09 (151) and B (22) viruses were sensitive to NAIs (2009-2011 seasons). For the first time in Russia oseltamivir-resistant A(H1N1) pdm09 influenza virus was isolated from the patient on the 5th day of a treatment course of this drug.

Abstract
The receptor specificity (RS) of pandemic influenza A(H1N1) pdm09 virus strains deposited into the State Collection of Viruses of the Russian Federation, D. I. Ivanovsky Research Institute of Virology, Ministry of Health and Social Development of Russia, in the 2009-2010 and 2010-2011 epidemic seasons to a panel of 9 sialoglycopolymers (SGP). The strains were divided into 3 groups according to the W(3/6) index proposed by the authors, which was equal to the amount of reactivities to unbranched alpha2-3-SGP to that of reactivities to unbranched alphal-6-SGP: W(3/6) < or = 1.0; 1.0 < W(3/6) < or = 1.5. The W(3/6) < or = 1.5 group showed a predominance of a2-3-RS, attended by the high incidence of fatal primary viral pneumonias (FPVP) (60.0%) and amino acid replacements in the HA1 receptor-binding site (RBS) (80.0%): D222{G, N} and Q223R. The 1.0 < W(3/6) < or = 1.5 group was characterized by mixed alpha2-3/alpha2-6-RS with the incidence of FPVP (29.7%) and amino acid replacements in the HA1 RBS (40.5%) (D222{G, N, V} and Q223), respectively. In the W(3/6) < or = 1.0 group, alpha2-6-RS was prevalent, FPVPs were absent and amino acid replacements in HA1 RBS (D222{G, E}) were seen only in 6.0% of cases. The number of strains with increased specificity to alpha2-3-sialosides increased in the 2010-2011 epidemic season as compared to the previous season. With their further spread among the population, there may be a rise in cases of severe primary viral pneumonias with possible fatal outcomes, which can be, however, accompanied by a decrease in the capacity of mutants to air-dropwise transmission.

Abstract
The paper gives the results of monitoring the circulation of influenza viruses in the 2010-2011 season, that covers the second year of circulation of pandemic A(H1N1)v virus strains, and their interaction with seasonal A (H3N2) and B strains. Unlike the previous season, the beginning of an increase in morbidity was recorded in January 2011; its peak in the most of contiguous areas was noted at 5-7 weeks of 2011, with its further decline to threshold levels at week 11 of 2011. Preschool and school children were most involved in the epidemic process. Three influenza virus strains (A(H1N1)v, A(H3N2), and B) were found to circulate. Differences were found in the level of participation of the isolated strains in individual areas of the Russian Federation. Detailed typing of the isolated strains determined the compliance of the vast majority of them with vaccine viruses. The pandemic influenza A(H1N1)v virus strains retained their susceptibility to oseltamivir and were resistant to rimantadine. The participation of non-influenza acute respiratory viral infection pathogens was estimated as follows: 11.9% for parainfluenza viruses, 5.9% for adenoviruses, and 3.5% for PC viruses, and 0.7% for pneumonia Mycoplasma, which was comparable with the previous epidemic seasons.

Abstract
This review focuses on arborviral infections associated with California serocomplex (Bunyaviridae, Orthobunyavirus). Results of relevant eco-epidemiological and clinical studies in Russia are presented suggesting the ubiquitious nature of diseases caused by viruses of the California encephalitis serocomplex (Inko, Tahyna, Snowshoe Hare). The etiologic structure of these diseases in taiga and mixed woods of the European part and Western Siberia is dominated by the Inco virus and in southern regions by Tahina. The diseases have a well apparent seasonal pattern (July-August) in agreement with the peak summer activity of the pathogens. Two clinical forms of pathology are distinguished, influenza-like and generalized, the latter affecting lungs, kidneys, liver, and CNS. The Inco virus plays a key role in pathogenesis of the generalized form affecting CNS.

Abstract
AIM To assess efficacy and safety of ingavirin in the treatment of the flu caused by pandemic virus of flu A (H1N1) sw1 in hospitalized patients compared with oseltamivir. MATERIAL AND METHODS A population-based comparative multicenter trial included 194 patients with verified diagnosis of the flu aged 18-60 years with marked clinical symptoms, body temperature over 38 degrees C and duration of the disease 48 hours maximum. The patients were randomized into 2 groups: group 1 (n=152) received ingavirin (90 mg once a day), group 2 received oseltamivir (n=42) in a dose 150 mg twice a day. Duration of the course was 5 days. RESULTS Ingavirin and oseltamivir normalized body temperature within treatment hours 24-36 if therapy was initiated in the first disease hours 27.0 +/- 10.0 and 31.9 +/- 10.4. Mean duration of the fever for ingavirin was 35.1 +/- 14.5 hours, for oseltamivir--26.3 +/- 13.0 hours (p < 0.817). The antiviral medicines significantly reduced duration of intoxication (head ache, weakness), catarrhal symptoms (cough, tracheitis, rhinitis), rate of complication vs. patients untreated with antivirus drugs (n=30). CONCLUSION The results of the treatment show safety and efficacy of ingavirin in uncomplicated flu caused by pandemic virus of flu A (H1N1) sw1 in inpatients. Early etiotropic therapy is a basic treatment policy able to reduce the number of severe complications and lethality.

Abstract
Oseltamivir (Tamiflu) is recommended by WHO experts as a drug to treat and prevent of influenza and to create stocks if its new pandemic variant occurs. The susceptibility of influenza viruses to oseltamivir was studied by polymerase chain reaction-based techniques detecting specific mutations in the neuraminidase gene. The increase in the number of oseltamivir-resistant influenza viruses, isolated from the Russian Federation, with type 1 neuraminidase H274Y mutation from 49% (2007-20008) to 92% (2008-2009) did not depend on the frequency of oseltamivir use. Full correlation of the results obtained by various techniques allows them to be used to monitor the susceptibility of influenza viruses to oseltamivir.

Abstract
The paper gives the results of sequence analysis of 150 positive samples in real-time RT-PCR, including 47 autopsy materials from patients (including 10 pregnant women), who died from fatal pneumonia mainly in November-December 2009, in whom the lifetime etiological diagnosis had not been made and hence no early etiotropic therapy performed. 70% of the primary materials from the deceased patients were found to have pandemic influenza A(H1N1) v mutants in the lung tissue with D222G (15%), D222N (15%), D222E (2%) substitutions, as well as a mixture of mutants (38%). Nasopharyngeal lavages from 3 Chukotka deceased patients exhibited only consensus (nonmutant) D222 virus variants; there was a mixture of consensus and mutant virus variants in the trachea and a mixture of mutant ones in the lung. Preliminary data from the study of the interaction of the hemagglutinin of two strains having D222G and D222N mutations with 9 oligosaccharides imitating the variants of cell receptors for influenza A virus suggest that there is a double receptor specificity for alpha2'-3' and alpha2'-6'-sialosides with a preponderance of alpha2'-3'-specificity. Further spread of the mutants that have acquired a high virulence and preserved their capacity for the respiratory route of human infection may lead to the situation similar to that seen in the 1918-1919 pandemic. Another scenario for evolution of the virus is to preserve its receptor specificity for alpha2'-3'-sialosides and high virulence with losses of alpha2'-6' specificity and capacity for aerosol transmission, by damping the pandemic.

Abstract
The paper presents the results of the investigations of the development of a influenza A(H1N1)v pandemic, conducted by the D. I. Ivanovsky Research Institute of Virology, Russian Academy of Medical Sciences, and collaborating laboratories in the European part of Russia, in the Urals, Siberia, and in the Far East. In the prepandemic period (April 27 - June 11, 2009) its first diagnosis was established on May 21, 2009; the first strain was isolated on May 24, 2009; the data on complete genome sequencing were sent to the GenBank; the sensitivity of the strain to commercial antiviral commercial agents was studied. In the early pandemic period (June 11 - August 15), 73 patients who had come from 14 countries of Europe, America, and Asia were identified; 19 virus strains (partially or completely sequenced) were isolated. The pandemic period (August 15 - December 1) was marked by absolute dominance of pandemic influenza virus virtually in the absence of seasonal influenza; the first death caused by pandemic influenza was detected in late August; 3053 subjects were infected with the pandemic strain, as shown by polymerase chain reaction diagnosis; 202 strains were identified.

Abstract
The paper presents the results of the first isolation of the new influenza virus in Moscow and the Russian Federation, which was similar to the swine A/IIV-Moscow/01/2009(H1N1)swl strain isolated on May 24, 2009 from a Russian arrived in Moscow from the USA on May 19, 2009. The antigenic, biological, and molecular genetic properties of this virus were studied. The virus was isolated on MDCK and chick embryos, the hemagglutination titers being 1:8-1:16 AE; the infectious titers being 6.51g of the tissue cytopathogenic infective dose (TCID50) and 7.01g of the common infective dose (CID50). The virus was sensitive to arbidol, ribavirin, oseltamivir, and resistant to rimantadine. The complete virus genome was sequenced; the data were accepted to the Gen Bank on May 28, 2009 under GQ219584-GQ219590 and GQ202724. The significant gene substitution of neuraminidase Asp for Gly in position 451, which has been undetectable in any other strain published in the Gen Bank by the present time is unique only to A/IIV-Moscow/01/2009 (H1N1)swl. The virus has been deposited in the State Collection of Viruses, D. I. Ivanovsky Institute of Virology, Russian Academy of Medical Sciences, under No. 2452 dated May 24, 2009.

Abstract
In 2007-2008 in Russia, the epidemic upsurge of influenza morbidity was caused by the active circulation of influenza A(H1N1, A(H3N2), and B viruses. The center for Ecology and Epidemiology of Influenza studied 334 epidemic strains. The results of a comparative study of the svirus specificity of commercial test systems (AmpliSens Influenza virus A/B and AmpliSens Influenza virus A/H5N1) for the polymerase chain reaction diagnosis and virological assays, including virus isolation, revealed their high correlation, which confirms that they may be expensively used to monitor the circulation of influenza viruses in the Russian Federation. All the strains were isolated in the MDCK cell culture. Influenza A(H1N1) viruses (n = 127) were antigenic variants of the reference strains A/Solomon Islands/3/06 and A/Brisbane/59107. Influenza A(H3N2) viruses (n = 49) were antigenic variants of the reference strains A/Wisconsin/67/05 and A/Brisbane/10/08. One hundred and fifty seven Influenza B strains were drift variants of the reference strains B/Florida/4/06 and B/Shanghai/361/02 of lineage B/Yamagata/16/88 and one strain, a variant of Malaysia/2506/04 related to lineage B/victoria/2/87. The isolates interacted actively with human 0(I) blood group erythrocytes and much more weakly with chicken ones. All study influenza A(H1N1) viruses (n = 74) preserved their sensitivity to rimantadine while 24 (77%) of the 31 study influenza A(H3N2) virus strains were resistant. A study of the time course of changes in the generation of antibodies in the donor sera obtained in Moscow and the Moscow Region in different periods of the epidemic process revealed an increase in antibodies to the reference influenza A and B virus strains circulating in this period.

Abstract
The paper presents the results of studying the spectrum of influenza A and B viruses to rimantadine, arbidol, and oseltamivir and describes the methods used for these purposes for epidemiological surveillance. Different sensitivities to rimantadine were found among influenza A viruses. During the 2007-2008 season, the vast majority of influenza A(H3N2) virus strains were resistant to rimantadine (77%) while all influenza A(H1N1) virus strains preserved their resistance to this drug. The fact that the epidemic influenza A(H1N1) virus strains that carry the mutation responsible for resistance to the neuraminidase inhibitor oseltamivir (Tamiflu) circulated in the Russian Federation was first established. At the same time all the study influenza A(H1N1) virus strains preserved their susceptibility to rimantadine. The sensitivity of the epidemic strains to arbidol has been confirmed.

Abstract
The population interactions of West Nile virus in the middle and lower regions of the Volga delta in 2001-2006 were studied. The authors established major species of the mosquitoes Anopheles messeae, An. hyrcanus, Culex piplens, Cx modestus, Coquilletidia richiardii in anthropogenic biocenoses and An. hyrcanus, Coq. richiardii in the natural ones; vertebrates - crows (Corvidae) and domestic animals in the anthropogenic biocenoses and cormorants in the natural ones. The ticks Hyalomma marginatum were found to play an active role in the circulation of the virus and in the stability of infection foci. The epicenter of an endemic area is situated in the anthropogenic biocenoses of the middle belt where high infection rates were found in humans (20-40% immune stratum), mosquitoes, and birds. A complete sequence of 14 strains was detected in 44% from 1 to 5 nucleotide replacements to a genome, most frequently at E154 positions Asn --> Ser and Ser --> Pro, which prevents glycosylation and reduces neuroinvasion. Analysis of 100 RT-PCR-positive samples revealed the absolute predominance of genotypes 1 with single findings of genotype 2 and 4.

Abstract
AIM To compare therapeutic efficacy and safety of ingavirin and arbidol in patients with influenza. MATERIAL AND METHODS The trial included 105 patients with a verified diagnosis of influenza, definite clinical symptoms, body temperature at least 38 degrees C and duration of the disease 36 hours maximum. Ingavirin efficacy was analysed basing on the evidence for 100 patients with uncomplicated influenza. The patients were randomized into three groups: taking ingavirin in a single daily dose 90 mg (n = 33), placebo (n = 36) or arbidol (200 mg 4 times a day). The duration of the treatment was 5 days. RESULTS Intake of ingavirin in initial 24-36 hours of the disease significantly reduced fever compared to placebo and arbidol (34.5, 72.0 and 48.4 hours, respectively). Ingavirin was less toxic and had no side effects. CONCLUSION Ingavirin is safe and effective in the treatment of influenza. By some criteria it is more effective than arbidol.

Abstract
The epidemic upsurge of influenza morbidity in the 2006-2007 season in Russia was caused by the active circulation of influenza A(H1N1), A(H3N2) and B viruses. The Center for Ecology and Epidemiology of Influenza studied 259 epidemic strains; All the strains were isolated on MDCK cell cultures. Influenza A(H1N1) viruses (n = 101) were antigenic variants of the references A/New Caledonia/20/99 and A/Solomon Islands/3/06. Influenza A(H3N2) viruses (n = 98) were antigenic variants of the references A/California/7/07 and A/Wisconsin/67/05. Twenty four influenza B virus strains were drift variants of the reference BI Shanghai/361/02 - lineage B/Yamagata/16188 and 36 were related to A/Malaysia/2506/05 - lineage B/Victoria/2/87). All the isolated strains actively interacted with human erythrocytes of the blood groups 0(I) and A(II) and very slightly with chicken ones. Twenty-two (48%) A(H1N1) strains and 19 (35%) A(H3N2) strains which were resistant to rimantafine were revealed. Studies of the donor sera collected in Moscow and the Moscow Region, the Jewish Autonomous Region, and Primorye revealed antibodies to today's strains; the level of antibodies in the preepidemic period depended on the region and strain. A study of changes in antibody formation in different periods of an epidemic process showed a rise in antibodies mainly to influenza A and B virus strains circulating in this period.

Abstract
Solid-phase enzyme immunoassay, neutralization test, and the hemagglutination-inhibition test were used to study the sera from human beings (152 samples), agricultural animals (n = 77), hares (n = 3), and wild birds (n = 69), collected in 2006-2007 in the Kuban River estuary (Temryuk District, Krasnodar Territory). There were specific antibodies against viruses of West Nile (WH), tick-borne encephalitis (TBE) (Flaviviridae, Flavivirus), Sindbis (Togaviridae, Alphavirus), the antigenic complex of California, Batai (Bunyaviridae, Orthobunyavirus), Dhori (Orthomyxoviridae, Thogotovirus). The findings suggest the presence of arboviruses from 6 transmitting mosquitoes and ticks in the study area and human infection by the viruses of the antigenic complex of California (20-47%), Batai (3-15%), West Nile (3-12%), Dhori (2%). The index agricultural animals (horses, cattle) were observed to have specific antibodies to the viruses of WN (8-15%), TBE (0-2%), Sindbis (2-9%), the antigenic complex of California (27-54%). Out of the representatives of the wild fauna, virus-neutralizing antibodies to Sindbis virus were found in European hares (Lepus europaeus), California complex virus in gulls (Larus argentatus) and terns (Sterna hirundo), WN and Sindbis viruses in herons (Ardea purpurea), and WN and California complex viruses in bald-coots (Fulica atra).

Abstract
One hundred and one patients at the age of 18 to 60 years suffering from influenza were observed during increased ratio of the sickness due to the influenza virus types A (H1N1 and H3N2) and B. The diagnosis of influenza was confirmed by the laboratory tests. Viferon was used in the treatment of 35 patients. The randomized double blind placebo-controlled study revealed high therapeutic efficacy ofviferon and its immunomodulating effect on the T-cells, the neutrophil phagocytic activity and the decrease of the levels of the circulating immune complexes. Viferon and arbidol decreased the fever periods and the toxicosis symptoms vs. the placebo. The therapeutic efficacies of viferon and arbidol were on the whole comparable, whereas the clinical findings and the results of the immunological tests were evident of the viferon higher therapeutic and immunomodulating efficacy. No side effects of the drugs were recorded. The tolerability was excellent. Viferon can be recommended for the treatment of influenza in adults.

Abstract
The laboratory verified cases of Crimean-Congo hemorrhagic fever (CCHF) in the piedmont steppes of the North Caucasus (Malgobeksky District, Republic of Ingushetia) are first described. The source of the first infection was Ixodidae ticks; three subsequent sources were contacts with the bloody discharges from patients. CCHF virus genome was detected in the blood of the cattle from an epidemic focus and in the pools of the Ixodes ticks Haemaphysalis parva Neum., 1897 and Boophilus annulatus Say, 1821, taken from cattle. The problem of including the piedmont steppes of the North Caucasus into the CCHF nosological area is discussed.

Abstract
The strains of influenza A -A(H1N1), A(H3N2) and B viruses were shown in the paper to have been circulating in Russia in 1999-2002. A co-circulation of viruses of 2 to 3 types was detected in all epidemic seasons. A majority of strains was isolated on the culture of cells MDCK. A study of epidemic strains revealed the predominance of viruses A(H3N2) in 1999-2000, the predominance of viruses A(h1N1) in 2000-2001, and the predominance of influenza B viruses in 2001-2002. According to the conducted antigenic analysis, all A(H1N1) isolates were similar to the etalon A/New Caledonia/20/99. The antigenic drift of hemagglutinin of A(H3N2) epidemic strains was oriented towards the etalons of A/Sydney/5/97--A/Moscow/10/99; while in influenza B viruses it was oriented towards the etalons B/Beejing/184/93--B/Yamanashi/166/98--B/Sichuan/379/99. Sequencing of hemagglutinin gene HA1 showed certain difference in the gene structure of epidemic strains A(H1N1) and A(H3N2) versus the etalon ones, which were registered, including at antigen sites. An analysis of paired sera obtained from patients confirmed the virologic findings, i.e. it detected a growth of antibodies to viruses that circulated during an actual season.

Abstract
Circulation of influenza A(H1N1) viruses in Russia and CIS countries had a wave-like pattern with period of silence in 1990-1995 and activation in 1995-1998, when these viruses were isolated together with A(H3N2) and B viruses. Antigenic drift of epidemic strains' hemagglutinin (HA) was directed to alteration of HA in reference strains A/Texas/36/91, A/Johannesburg/82/96, and A/Beijing/262/95. A/Moscow/17/98 strain similar to A/Beijing/262/95 was isolated on MDCK cells for the first time in European Russia. This means that A/Beijing/262/95 (H1N1) spread sporadically in the country at that time. Comparative analysis of HA thermosensitivity of influenza A(H1N1) strains of 1977-1998 showed a tendency to increase of their thermal stability. The sensitivity of erythrocytes of different animals to A(H1N1) strains isolated during the same epidemic season was different. Differences in amino acid sequences of epidemic strains' HA varied from 5 to 14 sites in comparison with the reference strains, depending on the reference strain and year of isolation.
