摘要
本文报告1989年6～8月对山东省莒南县进行的流行性出血热(EHF)病家对照家调查。经配比分析、分层分析和多元条件Logistic回归分析的结果表明,住室鼠患、使用捕鼠器、吃未防鼠食物和边缘住户均为本病危险因素,在统计学上有显著意义。病家成员隐性感染率(9.03%)高于对照家成员隐性感染率(1.74%),但隐性感染在年龄、性别间均无显著差异。鼠类的带毒率以褐家鼠最高(16.67%)。我们认为,该地春夏间EHF流行主要是家庭内感染所致,可能以消化道传播和接触宿主动物传播较为重要。
A case family-control family study of EHF (1:1, 78 pairs) was carried
out in Junan county in Shandong province from June to August, 1989. The
data were treated with X^2 test, stratified analysis and conditional Logistic
regression analysis. According to the statistical results, the risk factors
associated with EHF were rodent infestation in dwellings, using mousetrap,
eating the food without protecting to rats and marginal residence of a village.
Inapparent infection rate in case family members was much higher(9.03%)
than that in control family members(1.74%). No significant differece was
found in age and sex in inapparent infection individuals. The rate of virus
carriers of R. norvegicus (16.67%) was highest in that of all rat species
investigated. We think that the fol1owing facts should be paid attention to:
(1)Cases attacked with EHF were generally related to the house environm-
ent in Junan county from Spring to Summer. (2)Transmission routes may
be by way of digestive tract and contacting the host animals.
