自1981年中美专家对上海县的计划免疫进行综合评价后,近几年上海县在巩固和发展计划免疫成果方面,作出了积极的努力,取得了较好成果。白喉已连续11年、脊髓灰质炎已连续8年没有病例,麻疹已连续8年控制在10/10万以下,1986年发病率为0.25/10万,为历史最低水平。 Since China and the United States comprehensively evaluated planned immunization in Shanghai in 1981, Shanghai has made positive efforts in consolidating and developing the planned immunization in recent years and achieved good results. Diphtheria has been 11 consecutive years, polio has been for 8 consecutive years without cases, measles has been controlled for 10 years in a row for 10 years below 10 million in 1986, the incidence was 0.25 / 100,000, the lowest level in history.
