Abstract
OBJECTIVE To determine the clinical and epidemiological profile and circulating strains of rotavirus among children less than 5 y of age hospitalized for diarrhea in a tertiary care center of western Rajasthan. METHOD Children < 5 y of age admitted for acute gastroenteritis were recruited in this hospital-based surveillance study. Detailed clinical history and sociodemographic information was collected for all enrolled children. Severity of the gastroenteritis was assessed using the 20-point Vesikari Clinical Severity Scoring System. Rotavirus positivity was tested in the stool samples collected from children by commercially available techniques and further molecular characterization done as per defined protocol. RESULTS Out of 1055 enrolled children, overall positivity rate of typable rotavirus was 18.95% (169/892). Among children who were less than 24 mo of age, positivity due to rotavirus diarrhea was maximum (24.4%). Distinct seasonality was observed as maximum cases of rotavirus diarrhea were detected in the months of December to February. Commonest G type was G3 (54%) followed by G1 (19%) while predominant P type was P[8] (77%) followed by P[4] (11%). G3P[8] (51.83%) was the commonest genotype observed in the study region. CONCLUSION The current study found positivity of rotavirus to be 18.95% among children aged 0-59 mo admitted due to acute gastroenteritis is a tertiary care setting in northern part of India. Emergence of newer predominant strains emphasizes the need of continued surveillance to determine the changing trends.

Abstract
OBJECTIVE To identify the burden of rotavirus acute gastroenteritis (AGE) and the genotypes presenting in the authors' area in the period after introduction of rotavirus vaccine in Universal Immunization Programme (UIP). METHODS Children aged less than 5 y and presenting to hospital for the treatment of AGE were enrolled into the study from January 2016 to June 2019. Clinical details including age, gender, extent of illness, number of stools, concomitant vomiting and fever, grade of dehydration, and associated illness were recorded. Stool samples were tested for rotavirus using a commercially available ELISA Kit. Genotyping was performed for the rotavirus antigen-positive samples. RESULTS Rotavirus positive AGE was seen in 14.2% of the children. High burden of rotavirus gastroenteritis was seen in the age group of 6-23 mo and more cases were observed from December to February months. In our region the prevalent rotavirus genotypes in positive samples are G3 and G1 in G-typing, P[8] and P[4] in P-typing, respectively. G3P[8] and G1P[8] are the most prevalent genotypes identified in our area with a frequency of 35.1% and 25.9%, respectively. Almost all the cases (97.7%) got discharged and only one patient has died. CONCLUSION The findings conclude a declining trend in the rotavirus positive AGE cases in the authors' area after introduction of Rotavac vaccine in the UIP.

Abstract
OBJECTIVE To estimate the prevalence of rotavirus diarrhea and its demographic, social, and clinical characteristics among children less than five years of age admitted in a rural tertiary care institute. METHODS This prospective hospital-based observational study was carried out during February 2016 to June 2019. Diarrheal admissions of children aged 0-59 mo were screened and those who met the inclusion criteria were included in the study. Sociodemographic and clinical information was collected using a case report form. Stool samples were collected within 48 h of admission and transported in cold chain every month to the referral laboratory situated at Christian Medical College for testing. RESULTS Among the children admitted with acute diarrhea, 148 (11.02%) were positive for rotavirus in the study. As per Vesikari scoring system, around three fourth (76.2%) of children were having severe or very severe diarrhea. Severity of diarrhea was more among rotavirus positive cases as assessed by the Vesikari scoring system. The rotavirus diarrhea showed a peak during November to February. CONCLUSION Rotavirus diarrhea is an issue of public health importance, particularly due to its association with the severe diarrhea. As evidenced from similar settings in the world, rotavirus vaccine introduction and increased coverage is the most important strategy towards prevention and control of rotavirus diarrhea.

Abstract
RNA viruses have high rate of replication and mutation that help them adapt and change according to their environmental conditions. Many viral mutants are the cause of various severe and lethal diseases. Vaccines, on the other hand have the capacity to protect us from infectious diseases by eliciting antibody or cell-mediated immune responses that are pathogen-specific. While there are a few reviews pertaining to the use of artificial intelligence (AI) for SARS-COV-2 vaccine development, none focus on peptide vaccination for RNA viruses and the important role played by AI in it. Peptide vaccine which is slowly coming to be recognized as a safe and effective vaccination strategy has the capacity to overcome the mutant escape problem which is also being currently faced by SARS-COV-2 vaccines in circulation.Here we review the present scenario of peptide vaccines which are developed using mathematical and computational statistics methods to prevent the spread of disease caused by RNA viruses. We also focus on the importance and current stage of AI and mathematical evolutionary modeling using machine learning tools in the establishment of these new peptide vaccines for the control of viral disease.

Abstract
INTRODUCTION Rotavirus infection accounts for 39% of under-five diarrhoeal deaths globally and 22% of these deaths occur in India. Introduction of rotavirus vaccine in a national immunisation programme is considered to be the most effective intervention in preventing severe rotavirus disease. In 2016, India introduced an indigenous rotavirus vaccine (Rotavac) into the Universal Immunisation Programme in a phased manner. This paper describes the protocol for surveillance to monitor the performance of rotavirus vaccine following its introduction into the routine childhood immunisation programme. METHODS An active surveillance system was established to identify acute gastroenteritis cases among children less than 5 years of age. For all children enrolled at sentinel sites, case reporting forms are completed and a copy of vaccination record and a stool specimen obtained. The forms and specimens are sent to the referral laboratory for data entry, analysis, testing and storage. Data from sentinel sites in states that have introduced rotavirus vaccine into their routine immunisation schedule will be used to determine rotavirus vaccine impact and effectiveness. ETHICS AND DISSEMINATION The Institutional Review Board of Christian Medical College, Vellore, and all the site institutional ethics committees approved the project. Results will be disseminated in peer-reviewed journals and with stakeholders of the universal immunisation programme in India.

Abstract
Background Diarrhea is a major source of morbidity and mortality among young children in low-income and middle-income countries. Human adenoviruses (HAdV), particular HAdV species F (40, 41) has been recognized as important causal pathogens, however limited data exist on molecular epidemiology of other HAdV associated with acute gastroenteritis. Methods In the present preliminary study, we performed a case-control study involving 273 children who presented diarrheal disease and 361 healthy children matched control in Children’s hospital of Hebei Province (China) to investigate the relationship between non-enteric HAdV and diarrhea. HAdV were detected and quantified using quantitative real-time PCR (qPCR) and serotyped by sequencing and phylogenetic analysis. Odds ratio (OR) was used to assess the risk factor of HAdV. Results HAdV were detected in 79 (28.94%) of 273 children with diarrhea including 7 different serotypes (HAdV 40, 41, 3, 2,1,5 and 57) with serotypes 40, 41 and 3 being the most dominant and in 26 (7.20%) of 361 healthy children containing 9 serotypes (HAdV 40, 41, 3, 2,1,5,57,6 and 31). A majority (91.14%) of HAdV positives occurred in diarrhea children and 65.38% in controls< 3 years of age. No significant difference in the viral load was found between case and control groups or between Ad41-positive patients and healthy controls. In addition to HAdV 40 and 41, HAdV 3 was also associated with diarrhea (OR = 17.301, adjusted OR = 9.205, p < 0.001). Conclusions Our results demonstrate a high diversity of HAdV present among diarrhea and healthy children and implicate that non-enteric HAdV3 may lead to diarrhea.

Abstract
BACKGROUND This is a prospective, multicentered study conducted in 9 large urban areas in Russia, in order to determine the burden of rotavirus gastroenteritis in children <5 years of age and the genotypes circulating during 1 rotavirus season. METHODS From November 2012 to May 2013, surveillance was conducted in Moscow, Saint-Petersburg, Vologda, Krasnodar, Krasnoyarsk, Novosibirsk, Yaroslavl, Khanty-Mansiysk and Vladivostok. Children <5 years of age presenting at outpatient clinics with acute gastroenteritis (AGE) of less than 72 hours duration were enrolled in the study. Stool samples were tested for rotavirus and positive samples were P- and G-typed. Clinical symptoms were captured by physicians and parents on Day 1. Symptom severity was analyzed by Vesikari scoring system. The direct expenses of parents caused by AGE were obtained from questionnaires provided to parents by phone. RESULTS A total of 501 were children enrolled. Stool samples were analyzed for 487 (97%) children, and 151 (31%) of those were rotavirus positive. Rotavirus gastroenteritis was associated with more severe clinical course (Vesikari score 11.4 ± 2.2) versus non-rotavirus gastroenteritis (Vesikari score 9 ± 3). The identified serotypes were G4P[8] 38.9%, G1P[8] 34.2%, G3P[8] 6%, G9P[8] 6%, G2P[4] 2% and G4P[4] 0.7%. The mean overall expenses of parents caused by rotavirus and non-rotavirus gastroenteritis were 143.7 USD and 128.8 USD, respectively. CONCLUSIONS Rotavirus accounted for 31% of all AGE-related outpatient visits. The major rotavirus genotypes were G1P[8] and G4P[8]. Rotavirus gastroenteritis was associated with significantly more severe clinical symptoms than non-rotavirus gastroenteritis. The average costs of rotavirus cases for parents of children were elevated against the same indications for non-rotavirus. These findings underscore the need for a safe and effective rotavirus vaccine in Russia.

Abstract
This study investigated whether the rotavirus infection rate in children is associated with temperature and air pollutants in Hangzhou, China. This study applied a distributed lag non-linear model (DLNM) to assess the effects of daily meteorological data and air pollutants on the rotavirus positive rate among outpatient children. There was a negative correlation between temperature and the rotavirus infection rate. The impact of temperature on the detection rate of rotavirus presented an evident lag effect, the temperature change shows the greatest impact on the detection rate of rotavirus approximate at lag one day, and the maximum relative risk (RR) was approximately 1.3. In 2015, the maximum cumulative RR due to the cumulative effect caused by the temperature drop was 2.5. Particulate matter (PM) 2.5 and PM10 were the primary air pollutants in Hangzhou. The highest RR of rotavirus infection occurred at lag 1-1.5 days after the increase in the concentration of these pollutants, and the RR increased gradually with the increase in concentration. Based on the average concentrations of PM2.5 of 53.9 μg/m(3) and PM10 of 80.6 μg/m(3) in Hangzhou in 2015, the cumulative RR caused by the cumulative effect was 2.5 and 2.2, respectively. The current study suggests that temperature is an important factor impacting the rotavirus infection rate of children in Hangzhou. Air pollutants significantly increased the risk of rotavirus infection, and dosage, lag and cumulative effects were observed.

Abstract
Diarrheal diseases are responsible for a significant proportion of mortality and morbidity all around the globe. The contribution of viruses to gastroenteritis incidences in humans is well established. In the present study, we have studied the prevalence of rotavirus, norovirus and enterovirus in Himachal Pradesh, a north Indian state. A total of 287 (111 children and 176 adults) stool samples of gastroenteritis patients were screened for the viruses using RT-PCR method. 34.5 % samples were positive for the viral pathogens of gastroenteritis. Rotavirus was the predominant virus detected in the study with 49.5 and 14.8 % positivity in children and adults, respectively. Enterovirus was present in 5.6 % cases whereas norovirus had least prevalence (1.4 %). Co infection (rotavirus and enterovirus) was witnessed at the prevalence rate of 0.6 %. Among different age groups, the prevalence of studied viruses was highest in the children belonging to the age groups of <5 years. Rotavirus infections were found to be significantly associated with vomiting and trend of higher rates of fever and dehydration was seen in children along with diarrhea. Seasonal distribution shows circulation of diarrheagenic viruses throughout the year. This is the first report of prevalence of various diarrheagenic viruses circulating in this region. The outcome of the study from this cohort provides a baseline data which can be used to design the preventive strategies in the otherwise unexplored state of Himachal Pradesh.
