Epidemiological study on the incidence of haemorrhagic fever with renal syndrome in five Western Balkan countries for a 10-year period: 2006-2015. Zoonoses Public Health 2022; 69:195-206. [PMID: 34989483 DOI: 10.1111/zph.12908] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 12/20/2021] [Accepted: 12/24/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Large-scale epidemics of haemorrhagic fever with renal syndrome (HFRS) have been reported mostly in Asia and Europe, with around 100,000 people affected each year. In the Southeast Europe, Balkan region, HFRS is endemic disease with approximately 100 cases per year. Our aim was to describe epidemiological characteristics of HFRS in five Western Balkan (WB) countries and to describe correlation between HFRS incidence and major meteorological event that hit the area in May 2014. METHODS National surveillance data of HFRS from Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia and Serbia obtained from 1 January 2006 to 31 December 2015 were collected and analysed. RESULTS In a 10-year period, a total of 1,065 HFRS patients were reported in five WB countries. Cumulative incidence rate ranged from 0.05 to 15.80 per 100.000 inhabitants (in North Macedonia and Montenegro respectively). Increasing number of HFRS cases was reported with a peak incidence in three specific years (2008, 2012, and 2014). Average incidence for the entire area was higher in males than females (5.63 and 1.90 per 100.000 inhabitants respectively). Summer was the season with the highest number of cases and an average incidence rate of 1.74/100.000 inhabitants across 10-year period. Haemorrhagic fever with renal syndrome incidence was significantly increased (7.91/100.000 inhabitants) in 2014, when a few months earlier, severe floods affected several WB countries. A strong significant negative correlation (r = -.84, p < .01) between the monthly incidence of HFRS and the number of months after May's floods was demonstrated for the total area of WB. CONCLUSION Our findings demonstrate that the HFRS incidence had similar distribution (general, age, sex and seasonality) across majority of the included countries. Summer was the season with the highest recorded incidence. Common epidemic years were detected in all observed countries as well as a negative correlation between the monthly incidence of HFRS and the number of months after May's cyclone.

Abstract
BACKGROUND Hantaviruses are etiological agents of emerging zoonotic diseases worldwide, including hemorrhagic fever with renal syndrome (HFRS). A number of hantavirus species is known to be present in Europe. In Serbia, existing data on hantavirus presence and prevalence rely in serological findings. In this study, molecular analysis was performed in order to characterize HFRS causing hantaviruses in Serbia. METHODS Sixty four serum samples of HFRS cases, previously found seropositive to anti-hantaviral antibodies, were included in the study. Partial hantaviral L and S segments were PCR amplified producing 390nt and 598nt amplicons, respectively, in parallel with human beta-actin mRNA as external reverse transcription positive control. Hantavirus specific PCR products were DNA sequenced in both direction and the obtained sequences phylogenetically confirmed and analyzed. RESULTS PCR detection of hantavirus L and S genome segments was positive in 18/64 and 11/64 tested samples, respectively. Positive PCR results involved samples obtained from different locations, mostly from central and southern parts of Serbia. All the obtained sequences were identified as Dobrava-Belgrade virus (DOBV). In the phylogenetic analysis sequences from Serbia tended to cluster in distinctive, geographically related clusters. CONCLUSIONS Our findings indicate DOBV as the main HFRS causing hantavirus in Serbia, the site of its initial isolation.

Abstract
In order to gain an insight into the genetic relatedness of the Dobrava-Belgrade virus (DOBV) in Greece, a phylogenetic analysis was performed based on all currently available DOBV sequences obtained from hospitalized cases with hemorrhagic fever with renal syndrome (HFRS). Most cases occurred in northwestern and north central part of the country. Two sequence datasets consisted of 41 S and 12 M partial DOBV RNA segment sequences were analyzed. All DOBV strains belong to Dobrava genotype which is associated with the rodent Apodemus flavicollis. In both phylogenetic trees (S and M segments), two main clusters of Greek strains could be distinguished. Phylogenetic analysis showed a spatial rather than temporal relation of the strains, since their genetic clustering was highly associated with the geographic distribution of the cases. Besides previous characterized endemic foci, novel ones have been identified, expanding our knowledge on the epidemiology of HFRS in Greece.

Abstract
INTRODUCTION Recently, hantaviruses have been discovered in insectivores in Europe, Asia, Africa, and North America. Imjin virus (MJNV) was first isolated from the lung tissues of Ussuri white-toothed shrew (Crocidura lasiura) from South Korea in 2009. We aim to detect the species and prevalence of insectivore- and rodent-borne hantaviruses in shrews and rodents. MATERIALS AND METHODS Shrews and rodents were captured in Jiaonan County of Shandong Province, China, in 2014. RT-PCR was used to amplify viral RNA of Hantavirus species, including insectivore-borne Imjin virus (MJNV), rodent-borne Hantaan virus (HTNV), and Seoul virus (SEOV) from shrews and rodents. RESULTS AND DISCUSSION We found that MJNV infected 10.7% (19/178) of Crocidura shrews, but it infected none of rodents (0/475); we also found that 2 of 178 (1.1%) Crocidura shrews were PCR positive to SEOV. This study indicated that the major animal hosts of Imjin virus are shrews, and rodent-borne SEOV can infect shrews.
