福建省近年来疟疾发病率逐年下降,1984年全省发生间日疟4429例,年发病率仅1.66%∞,然而小范围内的暴发点仍频频出现,且多发生于闽西北雷氏按蚊嗜人亚种分布区,为探讨其发生规律,1984年进行了以下调查。 方法 在全省疟区对“四热”(疟疾,疑似疟疾、原因不明及感冒发热)病人进行血检,在疟原虫阳性病例较前一年有明显增加的地点,对病例周围人群访问当年疟史或血检疟原虫,以自然村或工地为单位统计发病率。凡发病率比上一年成倍增加且发病人数在10例以上者列为疟疾暴发点。同时调查外来人口籍贯,人数、移入时间及疟疾发病率等情况。
In recent years, the incidence of malaria in Fujian Province has been declining year by year. In 1984, 4,429 cases of Plasmodium falciparum occurred in the province, with an annual incidence of only 1.66% ∞. However, outbreaks in small areas were still frequent and occurred frequently in An. Mosquito Anthropophagus distribution of sub-species, in order to explore the law of its occurrence, carried out in 1984 the following survey. Methods Blood samples were collected from the four hot areas (malaria, suspected malaria, unexplained and cold and fever) in the malaria area in the province. In the cases where the positive cases of malaria were significantly increased compared with the previous year, History or blood tests Plasmodium, in villages or sites as a unit of statistical incidence. Where the incidence doubled over the previous year and the incidence of more than 10 cases were listed as malaria outbreaks. At the same time, we will investigate the origin, population, immigration time and the incidence of malaria among migrant workers.
