Abstract
Background: Hemorrhagic fever with renal syndrome (HFRS) is an illness caused by hantaviruses. Numerous factors modify the risk of hantavirus transmission. This study explored the epidemiological characteristics, differences, and trends in terms of gender, age, season, and living areas of those diagnosed with domestically acquired HFRS in Taiwan from 2001 to 2019. Methods: We examined publicly available annual summary data on the domestic cases with HFRS from 2001 to 2019; these data were obtained from the web database of Taiwan’s Centers for Disease Control (CDC). Results: This study analyzed 21 domestic cases with HFRS from Taiwan’s CDC databases. In this study of the cases of HFRS in Taiwan, a gradual increase in the cases of those aged ≥40 years acquiring the disease was noted, and a distinct pattern of seasonal variation (spring) was observed. Furthermore, more men had domestically acquired HFRS, and living in Taipei metropolitan area (6 cases [28.6%]) and the rural areas (Gao-Ping region, 9 cases [42.9%]) was identified as a potential risk factor. This study represents the first report of confirmed cases of domestically acquired HFRS from surveillance data from Taiwan’s CDC, 2001–2019. Conclusion: This study highlights the importance of longitudinal studies covering a wide geographical area, particularly for highly fluctuating pathogens, to understanding the implications of the transmission of zoonotic diseases in human populations. Important data were identified to inform future surveillance and research efforts in Taiwan.
Highlights
Due to factors such as frequent international exchanges as well as a global climate and living environment changes, different emerging and re-emerging diseases are spreading rapidly
Related institutions conduct monitoring related to disease types or symptoms and lead to further follow-up studies. This is the first report in Taiwan concerning the epidemiological characteristics and trends of Hemorrhagic fever with renal syndrome (HFRS) cases from 2001 to 2019
In this study on the incidence of HFRS in Taiwan, a gradual increase in incidence was noted with patient age and a distinct pattern of seasonal variation was determined
