| 摘 要： | 本文收集了福建省1980年流行性脑脊髓膜炎(流脑)发病资料共3337例,划分为山区、平原及沿海三类地区,应用圆形分布计算其发病高峰时点,并对不同地区流脑发病高峰时间作了比较,提示不同地区发病高峰时间不同(P<0.01)。这对于不同地区流脑疫苗接种时间的合理安排提供了科学依据,为有效预防流脑发生和流行具有一定的现实意义。

| Abstract: | This paper collects the data which describe 3337 cases of epidemic cerebrospinal meningitis Fujian in 1980. The dataset is divided three categories, mountain area, plain and coastal. The peak time of epidemic cerebrospinal meningitis incidence is estimated by applying circular distribution. We have tested the difference of peak time of the disease incidence between categories. It imply that the peak time of the disease incidence are different in different categories (P<0.1). This provides scientific basis for arranging equitably time of inoculating vaccine in different categories. There is practical value for preventing epidemic cerebrospinal meningitis. |
