本地区一度几乎无病例报告的脊髓灰质炎在1989年出现了一起较大的爆发流行。1989年3～12月,共6个县相继出现爆发流行,病例数达88例为前9年报告病例总和的1倍多。主要发病年龄为0～4岁,农村地区儿童患病为主。脊髓灰质炎疫苗未接种者占总病例的67.0％,流行高峰主要集中于5～7月。所采取的糖丸疫苗快速应急接种和对病家周围环境的综合防治措施,取得了显著的控制效果。说明要消灭脊髓灰质炎,首要是完善计划免疫工作,提高糖丸疫苗接种率,才能有效地控制脊髓灰质炎的发病和流行。
Polio, an almost case-free report in the region, showed a larger outbreak in 1989. From March to December 1989, outbreaks occurred in 6 counties in succession, with 88 cases being more than double the sum of the reported cases in the preceding 9 years. The main age of onset is 0 ~ 4 years old, prevalence of children in rural areas. Poliomyelitis unvaccinated persons accounted for 67.0% of the total cases, the peak of the epidemic mainly concentrated in May to July. The rapid vaccination adopted by the pill vaccine and the comprehensive prevention and control measures for the surrounding environment of patients have achieved remarkable control effects. This shows that to eradicate poliomyelitis, we must first improve the planned immunization work and improve the vaccination coverage of sugar pills in order to effectively control the incidence and prevalence of poliomyelitis.
