Evaluating climate-dependent distribution of orthohantaviruses with monitoring wild rodents: One Health Perspective †. Braz J Microbiol 2024:10.1007/s42770-024-01447-2. [PMID: 39012426 DOI: 10.1007/s42770-024-01447-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Accepted: 06/29/2024] [Indexed: 07/17/2024] Open
Abstract
Orthohantaviruses, cause hemorrhagic fever with renal syndrome, nephropathia epidemica, and hantavirus pulmonary syndrome, are major public health problems all over the world. Wild rodent surveillance for orthohantaviruses is of great importance for the preparedness against these human infections and the prediction of possible outbreak regions. Thus, we aimed to screen orthohantaviruses in wild rodents in Southern Anatolia, where the area has some of the glacial period refugia in the Mediterranean Basin, and interpret their current epidemiology with climatic biovariables in comparison with previously positive regions.We trapped muroid rodents between 2015 and 2017, and screened for orthohantaviruses. Then, we evaluated the relationship between orthohantavirus infections and bioclimatic variables. In spite of the long-term and seasonal sampling, we found no evidence for Orthohantavirus infections. The probable absence of orthohantaviruses in the sampling area was further evaluated from the climatic perspective, and results led us suggest that Orthohantavirus epidemiology might be relatively dependent on precipitation levels in driest and warmest quarters, and temperature fluctuations.These initial data might provide necessary perspective on wild rodent surveillance for orthohantaviruses in other regions, and help to collect lacking data for a such habitat suitability study in a bigger scale in the future.

Abstract
Rodents are one of the most abundant mammal species in the world. They form more than two-fifth of all mammal species and there are approximately 4600 existing rodent species. Rodents are capable of transmitting deadly diseases, especially those that are caused by viruses. Viruses and their consequences have plagued the world for the last two centuries, three pandemics occurred during the last century only. The Middle East is situated at the crossroads of Africa and Asia, along with the Mediterranean Sea and the Indian Ocean, its geographic importance is gained through the diversity of topographies, biosphere, as well as climate aspects that make the region vulnerable to host emerging diseases. Refugee crises also play a major role in expected epidemic outbreaks in the region. Public health has always been the most important priority, and our aim in this review is to raise awareness among public health organisations across the Middle East about the dangers of rodent borne diseases that have been reported or are suspected to be found in the region.

Abstract
Background/aim Hantavirus is a rodent borne zoonosis caused by the members of the virus family Bunyaviridae, genus
Hantavirus
. In this study, we aimed to determine the role of peripheral blood leukocyte ratio in differential diagnosis of Hantavirus disease. Materials and methods The medical records of patients at the Düzce University Medical Faculty were examined retrospectively. A total of 20 patients diagnosed with hantavirus infection confirmed by serologic tests were included in the study (Group 1). The other group consisted of 30 patients suspected of hantavirus infection but found negative (Group 2). Demographic, clinical and laboratory characteristics, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte (LMR) ratios of both groups were compared. Results As a result of the istatistics analysis, no difference was found between the groups’ age, sex, and clinical complaints except lethargy-weakness (P = 0.004) and diarrhea (P < 0.001). Hemogram analysis showed a significant difference between the groups in terms of leukocyte, hemoglobin, hematocrit, platelet, mean platelet volume (P < 0.05) and PLR (P = 0.001) and LMR (P = 0.003) values from peripheral blood leukocyte ratios. Conclusion In conclusion, NLR, PLR, and LMR ratios may be useful for clinicians in differential diagnosis of Hantavirus in patients presenting with similar symptoms of Hantavirus disease.

Abstract
Orthohantaviruses infect humans via inhalation of the viral particles in the excreta of infected rodents or direct contact with infected rodents. The infections caused by Puumala orthohantavirus (PUUV) and Dobrava-Belgrade orthohantavirus (DOBV) have been reported in Turkey. Serum samples of 346 healthy volunteers who are in the high-risk group of Orthohantavirus infections among the residents of Çal, Baklan, Çivril, and Bekilli counties, located in the northeast part of Denizli province, were used in this study. The samples were screened and confirmed using commercial ELISA and immunoblot tests, which detect IgG antibodies against DOBV, PUUV, and Hantaan orthohantavirus. IgG antibodies against PUUV were detected in the samples of 2 volunteers (2/346, 0.6%). One was a veterinarian and the other a farmer and they live in the Baklan and Çal counties, respectively. Both of them have a high probability of exposure to the virus, based on their occupation and living conditions. However, no symptoms were found in the clinical findings of both cases. This study is the first publication of reported PUUV seropositivities from the southwestern part of Turkey.

Abstract
This review focuses on reports of hepatitis E virus, hantavirus, rotavirus,
coronavirus, and arenavirus in synanthropic rodents (Rattus
rattus, Rattus norvegicus, and Mus
musculus) within urban environments. Despite their potential impact
on human health, relatively few studies have addressed the monitoring of these
viruses in rodents. Comprehensive control and preventive activities should
include actions such as the elimination or reduction of rat and mouse
populations, sanitary education, reduction of shelters for the animals, and
restriction of the access of rodents to residences, water, and food
supplies.

Abstract
BACKGROUND Some of the hantavirus species in Euro-Asia cause haemorrhagic fever with renal syndrome (HFRS) in humans. The first documented human hantavirus infection in Turkey was diagnosed in 2009. This report describes the dynamics of the first hantavirus outbreak that emerged in humans in the Western Black Sea Region of Turkey. METHODS All the suspected cases of hantavirus infection were admitted to the Infectious Diseases and Clinical Microbiology Department at the Zonguldak Bülent Ecevit University Hospital in Zonguldak, Turkey. The patients were carefully interviewed, examined and evaluated using routine laboratory tests and hantavirus diagnostic tools. Hantavirus-reactive antibodies (IgM and IgG) in serum samples were detected via enzyme immune assay (EIA) and immunofluorescence assay (IFA) in the acute and convalescence stages of the disease. The presence of hantavirus ribonucleic acid (RNA) was analysed via reverse transcription polymerase chain reaction (RT-PCR) in serum and urine samples. A focus reduction neutralization test (FRNT) was performed to confirm specific hantavirus serotypes. In addition, a case-control study was conducted to identify possible risk factors for hantavirus transmission in the outbreak area. A control group was composed of asymptomatic individuals who were seronegative for hantavirus IgM and IgG and living in the outbreak area. RESULTS A total of 55 suspected cases of hantavirus infection were admitted to the inpatient clinic between February and June of 2009. Twenty-four patients were diagnosed with acute HFRS via EIA or IFA. In 22 of the 24 infected patients, Puumala virus (PUUV) was identified as the causative hantavirus type by detecting IgM in the acute stage and an increase in the IgG level in follow-up serum samples. PUUV was also verified as the infecting agent by FRNT in two of the 24 cases. Among the 24 laboratory-confirmed HFRS cases, 21 (87.5%) were males and 3 (12.5%) were females, and the mean age was 45.92 years (standard deviation ± 16.90 years). Almost all these individuals were living in villages or rural areas. The 24 HFRS cases were matched with 26 healthy controls for statistical analyses and according to binary logistic regression analysis, and dealing with rodent control activities in gardens or in annexes of their homes (p = 0.021 and Odds ratio [OR] = 17.11) and being male (p = 0.019 and OR = 22.37) were detected as statistically significant risk factors for hantavirus infection. The most commonly observed clinical complaints were fatigue (95.8%), shivering (91.7%), fever (87.1%), headache (70.8%) and nausea (70.8%). Haemodialysis was required for four patients (16.7%). Except for the first case diagnosed with acute hantavirus infection, no patient died. The mean delay time to hospital admission from initiation of symptoms was 5.3 days, the mean duration of febrile days was 2.6 days, and the mean duration of hospital stay was 8.5 days. CONCLUSION Hantaviruses are circulating in Turkey and causing sporadic or epidemic infection in humans. Additional investigations are needed to better understand the dynamics of hantaviruses in this country.

Abstract
Background/aim Hantavirus and Borrelia burgdorferi are two zoonotic agents that pose a great risk especially for people living in forest
areas. This study aimed to investigate the seroprevalence of hantavirus and B. burgdorferi in forest villages of Düzce and its relationship
with sociodemographic features. Materials and methods The presence of immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies against hantavirus and
B. burgdorferi in serum samples was investigated via enzyme-linked immunosorbent assay (ELISA). Hantavirus IgG and B. burgdorferi
IgM and IgG positivity was then validated by western blot (WB) method. Results During the analyses, 193 serum samples were tested. Eleven (6%) cases of hantavirus IgM was found positive by ELISA. Six
(3%) cases of hantavirus IgG, 3 (2%) cases of B. burgdorferi IgM, and 12 (6%) cases of B. burgdorferi IgG were found positive by WB.
Borrelia burgdorferi IgG positivity was found to be higher in the 46–70 age group and it was seen that the positivity was the highest
among those who lived in mud-brick houses. Conclusion This study was the first to determine the frequency of hantavirus in the study region and it includes current data for B.
burgdorferi. Consequently, it is recommended that similar studies be carried out on rodents in all the regions at risk.

Abstract
Orthohantaviruses (family Hantaviridae order Bunyavirales) are emerging pathogens with a significant impact on human health. They are transmitted via aerosolized excreta of rodents which also act as reservoir hosts, constituting a unique route for dispersion. Dobrava-Belgrade and Puumala orthohantaviruses have been previously reported from Anatolia, in rodents, case reports and occasional outbreaks. We have collected rodents at several locations during a surveillance study in eastern Anatolia. The specimens were morphologically-identified and various tissues were screened via a generic orthohantavirus reverse transcription polymerase chain reaction assay. DNA barcoding via mitochondrial cytochrome b sequencing was performed in rodents with detectable orthohantavirus sequences. High throughput sequencing was performed for viral genome characterization. Fifty rodents were collected and identified morphologically as Microtus spp. (96%) and Apodemus spp. (4%). Orthohantavirus sequences were detected in lung and spleen or liver tissues of 4 voles (8%), barcoded as Microtus obscurus. The virus sequences were identified as Tula orthohantavirus (TULV) and near-complete genomic segments of the prototype viral genome, tentatively named as the Tula orthohantavirus-Turkey (TULV-T), could be characterized. Putative open reading frames for viral nucleocapsid and a nonstructural protein on the S segment, glycoproteins G1 and G2 on the M segment and viral replicase on the L segment were identified on the TULV-T. Several minor sequence variants were further characterized. No evidence of recombination could be detected and pairwise comparisons displayed over 95% amino acid sequence identities to various Eurasian TULV strains. Phylogenetic analyses revealed distinct clustering of all genome segments from previously-characterized TULV strains via various approaches and models. Here, TULV-T constituted a novel lineage, forming an intermediate among Asian and European TULV lineages. This report describes the initial documentation of TULV circulation and its potential reservoir in Anatolia. The extent of virus dispersion, alternate hosts or outcomes of human exposure require elucidation.

Abstract
Despite development of preventive and controlling strategies regarding infectious diseases, they are still considered as one of the most significant leading causes of morbidity and mortality, worldwide. Changes in humans' demographics and behaviors, microbial and ecological alterations, agricultural development, international travels and susceptibility to infectious diseases have resulted in increased reports of emerging infectious diseases (EIDs) and reemerging infectious diseases (RIDs) in various geographical areas. Because of the various types of geographic properties in Iran, substantial climatic variability, as well as unstable political situations and poor public health conditions in some of neighboring countries, EIDs and RIDs are serious public health problems; among them, zoonotic and drug resistant diseases are the most significant. Hence, this review provides an overview of the significant bacterial, viral and fungal EIDs and RIDs in Iran regarding their epidemiological aspects.

Abstract
Viruses are the most abundant obligate intracellular entities in our body. Until recently, they were only considered to be pathogens that caused a broad array of pathologies, ranging from mild disease to deaths in the most severe cases. However, recent advances in unbiased mass sequencing techniques as well as increasing epidemiological evidence have indicated that the human body is home to diverse viral species under non-pathological conditions. Despite these studies, the description of the presumably healthy viral flora, i.e. the normal human virome, is still in its infancy regarding viral composition and dynamics. This review summarizes our current knowledge of the human virome under non-pathological conditions.
