摘要
本文通过对上海市徐汇区1956～1985年接种活疫苗前后麻疹流行病学的比较分析发现80年中(1956～1985年)麻疹的发病率曲线可分为四段:(1)1956～1965年为高流行年份:(2)1966～1967年为较低流行年份;(3)1968～1974年流行回升;(4)1975～1985年持续低水平。自1965年广泛接种嘛苗后,严格的周期性,季节性规律被打破,大流行被控制,出现季节推迟现象。小年龄发病大幅度下降,从而使大年龄病人相对增多。人群免疫水平普遍提高,病例呈高度散发。麻疹的发病率、死亡率和病死率显著下降。
This paper deals with the comparative epidemiological analysis of measles before and after the active vaccination from 1956 to 1985 in Xu Hui District, Shanghai. The results of the analysis showed that the measles morbidity curve could be divided into 4 sections during that period. The first section from 1956 to 1965 showed high attack rate. The second one from 1966 to 1967 indicated that the attack rate was comparatively low. The third section, 1968 to 1974, the attack rate was found raised again. The last one, 1975 to 1985, presented constant low attack rate.Since the active vaccination was carried out, no apparent epidemic cycle and seasonal outbreak occurred. The incidence among young children obviously decreased, while the incidence among adults relatively increased. Immunity level was generally elevated in population and only sporadic cases appeared. The morbidity, mortality and death rate were remarkably reduced.
