BackgroundHemorrhagic fever with renal syndrome (HFRS) and leptospirosis are seasonal rodent-borne infections in the Republic of Korea (Korea). The occurrences of HFRS and leptospirosis are influenced by climatic variability. However, few studies have examined the effects of local climatic variables on the development of these infections. The purpose of this study was to estimate the effect of climatic factors on the occurrence of HFRS and leptospirosis in Korea.MethodsDaily records on human cases of HFRS and leptospirosis between January 2001 to December 2009 were analyzed. The associations of climatic factors with these cases in high incidence provinces were estimated using the time-series method and multivariate generalized linear Poisson models with a maximal lag of 12 weeks.ResultsFrom 2001 to 2009, a total of 2912 HFRS and 889 leptospirosis cases were reported, with overall incidences of 0.67 and 0.21 cases per 100,000, respectively, in the study areas. The increase in minimum temperature (1 °C) at a lag of 11 weeks was associated with 17.8% [95% confidence interval (CI): 15.1, 20.6%] and 22.7% (95% CI: 16.5, 29.3%) increases in HFRS and leptospirosis cases, respectively. A 1-h increase in the daily sunshine was related to a 27.5% (95% CI: 18.2, 37.6%) increase in HFRS at a lag of 0 week. A 1% increase in daily minimum relative humidity and a 1 mm increase in daily rainfall were associated with 4.0% (95% CI:1.8, 6.1) and 2.0% (95% CI: 1.2, 2.8%) increases in weekly leptospirosis cases at 11 and 6 weeks later, respectively. A 1 mJ/m2 increase in daily solar radiation was associated with a 13.7% (95% CI: 4.9, 23.2%) increase in leptospirosis cases, maximized at a 2-week lag.ConclusionsDuring the peak season in Korea, climatic factors play a significant role in the development of HFRS and leptospirosis. The findings of this study may be applicable to the forecasting and prediction of disease outbreaks.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-017-2506-6) contains supplementary material, which is available to authorized users.

“…In the previous report, an almost identical pattern of HFRS incidence was identified in soldiers in endemic areas (7). Higher incidence of HFRS in the autumn, versus other seasons, could be attributed to the high numbers of hantavirus-infected rodents in Korea during this time (10, 11). Seroprevalence of hantaviruses in wild rodents in Korea confidently demonstrated that most wild rodent hantavirus infections occur in the autumn.…”

This study describes the epidemiology of hemorrhagic fever with renal syndrome (HFRS) in the past 10 yr (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) in Korea. During this period, a total of 3,953 HFRS patients and an average prevalence rate of 0.81 per 100,000 population were recorded, with a total of 40 fatal cases, corresponding to a case fatality rate of 1.01%. More HFRS cases were found in men than in women (57% vs 43%), and a higher prevalence rate of HFRS was observed in patients older than 40 yr (82.1%). The highest numbers of HFRS cases were found amongst farmers (35.6%). The majority of HFRS cases (71.3%) occurred in the last quarter of the calendar year (October to December). More HFRS cases occurred in the western part than in the eastern part of Korea (68.9% vs 31.1%). The incidence of HFRS was significantly higher (P < 0.001) in rural areas than in urban areas (80.3% vs 19.7%). HFRS still occurs commonly among men, in autumn, and in western rural area of Korea. http://dx.doi.org/10. 3346/jkms.2013.28.10.1552 • J Korean Med Sci 2013 28: 1552-1554 BRIEF COMMUNICATION Infectious Diseases, Microbiology & ParasitologyHantavirus infection induces 2 different diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS), mainly in Korea, far east Russia, and China and in the United States, respectively (1, 2). The viruses are transmitted to humans by the inhalation of excreta of rodents infected with hantaviruses (3). HFRS was first recognized during the Korean War in the early 1950s, and although a hantavirus vaccine has been developed, the disease remains a serious problem in Asia and Europe (1, 4), and especially among soldiers in Korea (5, 6). A 2006 report describes HFRS epidemiology in endemic regions in Korea during a relatively short period, 1995-1998 (7); however, an updated epidemiological study is necessary to better understand the current status of HFRS in Korea. This study provides a comprehensive epidemiological overview of HFRS during the past decade in Korea.Raw data were utilized from the National Notifiable Disease Surveillance System (NNDSS) website of the Korean Center for (Table 1). The prevalence rate (PR) of HFRS per 100,000 population and case fatality rate (CFR) were estimated by the criteria established by the World Health Organization (WHO), and the upper and lower limits of the 95% confidence interval (CI) were calculated. Statistically significant differences between the epidemiological aspects were determined at P < 0.05 and P < 0.01 using the chi-square test or the paired t-test. The data analyses were carried out using the statistical system software included in Microsoft Excel 2007.As shown in Table 1, the HFRS cases were analyzed according to the PR, CFR, gender, age, and occupation of the infected individuals. There were a total of 3,953 HFRS patients with an average PR of 0.81 (95% CI, 0.79-0.85) per 100,000 population and a total of 40 fatal cases with a CFR of 1.01% (95% CI, 0.7-1.3). A significantly higher number (P <...

“…However, the seroprevalence and infection of hantavirus in rodent and human populations of East Malaysia are still largely unknown. There were also several reported cases of rodents infected with hantavirus in neighbouring countries [i.e., China (Lin et al 2012;Wang et al 2000), South Korea (Lim et al 2012), Singapore (Wong et al 1985(Wong et al ,1988Johannson et al 2010), Indonesia (Plyusnina et al 2009;Ibrahim et al 2013), Thailand, Cambodia and Lao PDR (Nitatpattana et al 2000;Reynes et al 2003;Blasdell et al 2011Blasdell et al , 2016], which suggested that there was a possibility for the circulation of hantavirus in the rodent populations in East Malaysia.…”

Abstrak: Rodent tergolong dalam kumpulan Rodentia yang terdiri daripada tiga Famili di Borneo (Contoh: Muridae, Sciuridae dan Hystricidae). Ini termasuk tikus, tupai dan juga landak. Golongan ini tersebar di serata dunia dan dianggap sebagai haiwan perosak yang mengancam manusia dan haiwan ternakan. Sebahagian spesies rodent adalah sumber pembawa jangkitan Hantavirus (Famili: Bunyaviridae) yang menyebabkan penyakit zoonotik kepada manusia. Walaupun serum manusia pernah dilaporkan seropositif pada Hantavirus di Semenanjung Malaysia pada awal tahun 1980, informasi tentang jangkitan pada spesies rodent di Malaysia masih kekurangan. Populasi rodent di kawasan perumahan dan kawasan hutan di Sarawak telah disampel. Sejumlah 108 individu daripada 15 spesies telah ditangkap di kawasan perumahan (n = 44) dan kawasan hutan (n = 64). Kepelbagaian rodent di kawasan hutan secara signifikan lebih tinggi (H = 2.2342) berbanding rodent di kawasan perumahan (H = 0.64715) (p < 0.001 ujian Zar-t berdasarkan indeks Shannon). Rattus rattus dan Sundamys muelleri amat kerap dijumpai di kedua dua lokaliti. Ujian imunosorben taut-enzim (ELISA) menunjukkan antibodi kursus kepada Hantavirus tidak dapat dikesan daripada 53 sampel serum yang telah diuji. Ini adalah laporan pertama tentang seroprevalensi hantavirus di Sarawak, Malaysia Timur. Hasil kajian menunjukkan bahawa penyebaran Hantavirus tidak berada dalam populasi tikus yang ditangkap di Sarawak, melainkan jika pengesanan di bawah prevalensi rendah iaitu di bawah tahap ambang. Kajian lebih lanjut seperti pengesanan molekul pada komponen viral genetik diperlukan untuk menilai sepenuhnya risiko jangkitan Hantavirus pada rodent dan juga manusia dalam kawasan kajian ini, di Malaysia.Kata kunci: ELISA, Hantavirus, Mamalia Kecil Bukan Terbang, Rodents, Seroprevalensi Abstract: Rodents belong to the order Rodentia, which consists of three families in Borneo (i.e., Muridae, Sciuridae and Hystricidae).
