目的了解华亭县肾综合征出血热流行情况及鼠类种群密度和带病毒情况。方法采用夹夜法捕鼠,用描述流行病学现况分析方法,对1990-2007年华亭县肾综合征出血热报告病例进行分析。结果鼠总带毒率为1.47%,室内以褐家鼠为主,为1.20%。野外以社鼠最高,为7.14%,黑线姬鼠为5.71%。室内鼠种以褐家鼠、小家鼠为优势种群,分别占65.93%、31.85%,平均鼠密度为3.93%;野外以黑线姬鼠、灰仓鼠、大仓鼠、褐家鼠为优势种群,分别占24.14%、23.79%、17.24%、16.90%,平均鼠密度为6.48%。华亭县1990年首次发生肾综合征出血热,1991和1994年发病率分别达35.18/10万和98.86/10万,流行强度为高发水平。1995年发病率陡然下降为5.32/10万,之后连年处于低发水平。结论华亭县肾综合征出血热流行因素仍广泛存在,需进一步加强相关媒介的监测和防控工作。
Objective To understand the prevalence of haemorrhagic fever with renal syndrome and the population density and virus in Huating County. Methods Using the method of catching the night with the trap method, the descriptive epidemiological analysis method was used to analyze the reported cases of hemorrhagic fever with renal syndrome in Huating County from 1990 to 2007. Results The overall incidence of rat poisoning rate was 1.47%, indoor mainly Rattus norvegicus, 1.20%. In the wild, the highest rate of social rodents was 7.14% and that of Apodemus agrarius was 5.71%. The dominant species were Rattus norvegicus and Mus musculus, accounting for 65.93% and 31.85% of the total, respectively. The average rat density was 3.93%. In the wild, Apodemus agrarius, Accounting for 24.14%, 23.79%, 17.24% and 16.90% respectively, and the average rat density was 6.48%. Huating County first occurred in 1990, hemorrhagic fever with renal syndrome, the incidence in 1991 and 1994 were 35.18 / 100,000 and 98.86 / 100,000, the prevalence of high-intensity level. The incidence dropped sharply in 1995 to 5.32 / 100 000, after a year at a low level. Conclusion The prevalence of hemorrhagic fever with Renal Syndrome in Huating County is still widespread, so it is necessary to further strengthen the monitoring and prevention and control of related media.
