摘要: 目的:调查分析20年来肾综合征出血热(HFRS)疫情和监测结果。方法:间接免疫荧光试验等。结果:疫情呈单峰型特征,即1985年前呈阶梯式上升,1986年达高峰,1988年起又逐年下降;历年累计报告病人1568例,1986年发病率最高达49.50/10万;各乡镇均有发病,多数病例呈点状分布,相互间无明显联系,但有相对集中现象,大部分病例集中在永安溪中、下游平原丘陵地区;季节分布表现为双峰型;男女之比为1.89∶1,20~40岁青壮年占43.43%,农民占发病总数的88.01%。黑线姬鼠是主要传染源。疫区人群隐性感染率为2.42%。流行季节存在轻型、不典型病例漏诊的可能。结论:本县存在HFRS家鼠型和野鼠型疫源地;在检测鼠肺抗原的同时检测鼠血抗体,具有重要的流行病学意义。

Abstract: Aim Epidemic situation of HFRS have been investigated by author in Xianju County for 20 years.Method indirect immune fluorescent testing.Results Epidemic situation of sole peak appeared (epidemic situation increasing in stair-fashion before 1985,a peak in 1986,and decreasing year by year after 1988).Total cases of HFRS were 1 568 hitherto.The incidence of HFRS was 49.50 / 100 000 in 1986,which was the highest in the investigated years. The case of HFRS most of which were distributed in the shape of spot,was existing in all villages and towns.There was no evident relation among case of HFRS ,but there was a concentration relatively.Most of case were concentrated in the plain and hilly land of middle, lower reaches of YongAn brook. The type of both peak appeared in the distribution of season. The proportion of male to female was 1.89 ∶1. Young and robust people (at the age of 20-40) were 43.43 %, and the peasants were 88.01 % among all cases. In our county ,Apodemus agrarius Pallas and Rattus norvegicus Berkenhout were the main infectious sources of HFRS which appeared in focus of both family and wild types. It was demonstrated that the rate of recessive infection was 2.42 %, existing in the crowds of epidemic district. It was possible that leaked diagnosis of typical and atypical cases appeared in the season of HFRS. Conclusion It is suggested that examination of antigen of rats' lungs simultaneous with antibody of rats' sera were significant on epidemiology.
