黔东南州过去是贵州省的白喉高发地区,最高发病年份(1969年)达23.61/10万;开展计划免疫以后,全州十六县市绝大多数县已连续多年无病例,仅于凯里与台江两县(市)先后发生点状暴发流行。全州的白喉发病率连年下降,1988年为0.17/10万,1989和1990年连续两年无病例。为掌握人群的白喉免疫状况,预测白喉流行程度,评价免疫接种质量,我们于1990年11月抽样调查了人群血清白喉抗毒素水平,参阅黔东南州历史资料,现总结如下:材料与方法1.对象:于东部的天柱县与西部的丹寨
In the past, Qiandongnan Prefecture was the highest incidence of diphtheria in Guizhou Province (1969), reaching 23.61 / 100,000. After the planned immunization, the vast majority of counties in the state’s 16 counties had been without cases for many years, And two counties (cities) in Taiwan have occurred dot-like outbreak. The incidence of diphtheria throughout the state declined year by year, from 0.17 per 100 000 in 1988 to two consecutive years of no cases in 1989 and 1990. In order to grasp the diphtheria immune status of the population, predict the prevalence of diphtheria, and evaluate the immunization quality, we investigated the level of serum diphtheria anti-toxin in the population in November 1990. Refer to the historical data of Qiandongnan Prefecture, and are summarized as follows: Materials and Methods 1. Object : Tianzhu County in the east and Danzhai in the west
