目的通过对一起病毒性脑膜炎暴发的流行病学调查,为病毒性脑膜炎防控提供依据。方法采用描述性流行病学方法,疫情资料运用EpiData软件录入,采用SPSS 17.0软件进行整理分析。结果病例标本核酸检测证实是埃可30型肠道病毒所致病毒性脑膜炎,疫情持续达28 d,罹患率为10.44%,76.32%的病例发生在中(2)和中(3)班,这2个班的罹患率分别是45.24%和23.81%。结论本起暴发可能与早期病例没有及时隔离,通过日常接触传播引起有关。对托幼机构等儿童聚集单位,应加强因病学生及时追踪和隔离,是防止传染病蔓延、减少暴发的关键。
Objective To provide a basis for prevention and control of viral meningitis through epidemiological investigation of an outbreak of viral meningitis. Methods Using descriptive epidemiological methods, epidemic data were recorded by EpiData software and analyzed by SPSS 17.0 software. Results The nucleic acid of the specimens was confirmed to be viral meningitis caused by Enterovirus type 30 enterovirus, the epidemic lasted for 28 days and the attack rate was 10.44%. The cases of 76.32% occurred in the middle class (2) and the middle class (3) The attack rates of the two classes were 45.24% and 23.81% respectively. Conclusions This outbreak may not be isolated in time from early cases and caused by daily exposure. For children and child care units such as nurseries and kindergartens, the timely tracking and isolation of sick children should be strengthened to prevent the spread of infectious diseases and reduce the outbreak.
