为了解传播程度不同疟区的人群行为方式有无差异,特在泰国南部春蓬府的Lamae区进行此项调查。该地平均气温和相对湿度分别波动在18.1℃～37.5℃和31.0%～99.0%,年均降雨量796.8mm,微小按蚊是主要的传疟媒介,间日疟为主,一年对房屋进行两次DDT滞留喷洒。调查在Lamae区的第11村和第13村进行。1989年第11村疟疾年患病率为4.7%,间日疟与恶性疟之比为2:1,第13村则分别为19.3%和3:1。两村疟疾感染的方式相似,低传播期和高传播期分别是在2月份和6月份,这两个月份
To investigate whether there is any difference in the patterns of behavior of people in different endemic areas of malaria, this survey was conducted in Lamae district, Chumphon Province, in southern Thailand. The average temperature and relative humidity fluctuated between 18.1 ℃ ~ 37.5 ℃ and 31.0% ~ 99.0%, respectively, with an average annual rainfall of 796.8mm. Anopheles minimus was the major malaria vector, Twice DDT stranded spray. The investigation was conducted in villages 11 and 13 in Lamae district. The annual prevalence of malaria in the 11th village in 1989 was 4.7%. The ratio of Plasmodium vivax to Plasmodium falciparum was 2: 1, while that of the 13th village was 19.3% and 3: 1, respectively. The two villages have similar malaria infection patterns, with low and high transmission periods in February and June, respectively, during the two months
