Abstract:
Objective:To analyze the epidemic characteristics and periodicity of hemorrhagic fever with renal syndrome (HFRS) in Jingzhou City, Hubei Province, and provide a basis for scientific prevention and control of HFRS in Jingzhou City.Methods:Retrospective analysis was used to collect HFRS case data and population data of Jingzhou City and 8 counties (cities, districts) within its jurisdiction, including Shashi District, Jingzhou District, Gongan County, Jianli City, Jiangling County, Shishou City, Honghu City, and Songzi City from 1962 to 2020, from the Archives of the Jingzhou Center for Disease Control and Prevention and the Infectious Disease Report Information Management System of the China Disease Control and Prevention Information System; and the epidemic characteristics of HFRS was analyzed in Jingzhou City and 8 counties (cities, districts) within its jurisdiction. The periodicity of HFRS onset was determined using wavelet analysis.Results:From 1962 to 2020, 18 936 HFRS cases were reported in Jingzhou City, with an average incidence rate of 5.95/100 000. There were a total of three epidemic peaks, namely from 1972 to 1973 (24.82/100 000, 24.84/100 000), 1983 (60.08/100 000), and 1995 (14.57/100 000). According to different regions, the high incidence areas of HFRS showed a phased transfer trend: from the 1960s to the 1970s, the Jiangbei area (Honghu City, Jianli City) was the highest incidence area; in the 1980s and 1990s, the high incidence areas were transferred to Jiangnan area (Songzi City, Shishou City, and Gongan County); after 2005, high incidence areas were relocated to Jiangbei area (Honghu City, Jianli City, Jiangling County). The wavelet analysis results showed that there were 12.30 and 21.77 years of HFRS epidemic cycles in Jingzhou City before 2000 ( P < 0.05); among them, the periodicity of Shashi District, Gongan County, Jiangling County, Shishou City, and Honghu City was relatively consistent with that of Jingzhou City, with epidemic cycles of about 12 or 22 years ( P < 0.05). Conclusions:Jingzhou City is currently at the peak of a 22-year epidemic cycle of HFRS, with Jiangbei area as the high incidence areas. The 12-year epidemic cycle in Jingzhou City has ended after 2000.
