石家庄地区自1984年发生流行性出血热(以下称EHF)以来,发病率经过了1986至19883年高峰时期,褐家鼠已被证实为我区EHF主要传染源宿主动物。为了摸清褐家鼠疫情动态与人间流行规律,我们于1986年始进行了5年动态观察,结果报告如下。 材料与方法 一、对我区不同流行强度的9个县、市,于1986年至1990年逐年分阶段进行连续监测。 二、定点调查,选择我区疫区流行强度不同的3县8个自然村为调查样地,自1986年11月至1987年10月,逐月进行定点连续监测。
Since the epidemic hemorrhagic fever (hereinafter referred to as EHF) occurred in 1984 in Shijiazhuang area, the incidence rate has gone through the peak period from 1986 to 19883. Rattus norvegicus has been confirmed as the main source of host EHF infection in our district. In order to find out the dynamics of the epidemic of Rattus chinensis and the epidemic pattern of human beings, we conducted a dynamic observation of five years since 1986 and the results are reported as follows. Materials and Methods 1. Nine counties and cities with different prevailing intensities in our district were continuously monitored in phases from 1986 to 1990 year by year. Second, sentinel surveys, select the epidemic areas of different epidemic intensity of 3 counties 8 villages for the sample area, from November 1986 to October 1987, month by month for continuous monitoring.
