1986年疏附县疟疾流行病学调查分析表明,长潜伏期间日疟占疟疾总病例数的一半。为了进一步证实该县长潜伏期间日疟虫株的存在,笔者于1986～1990年分别采用新生儿自然感染疟疾观察、伯氨喹预防性根治的现场实验和人工感染间日疟的实验方法,在天山南麓的帕合太克里乡(北纬37°27′,东经75°58′,以下简称帕乡)进行了初步观察。结果如下。1 实验方法 1.1婴儿新感染调查选择1986年4月至1987年2月本地出生的婴儿,在疟疾发病季节,每周进行主动侦查2次;在传播休止期作被动侦查,连续观察1年,并记录有无外出史。凡有发热症状者作血检,发现疟原虫阳性的本地感染的婴儿,计算其潜伏期。
Epidemiological survey of malaria in Shufu County in 1986 showed that malaria accounted for half of the total number of malaria cases in the long incubation period. In order to further confirm the presence of P. falciparum strain during the latent period of the magistrate, the author used malaria observation of natural infection in newborns, on-site experiment of primaquine prophylaxis, and experimental method of artificial infection of P. vivax between 1986 and 1990 respectively. Piedam Kailiang at the southern foot of the Tianshan Mountains (latitude 37 ° 27 ’, longitude 75 ° 58’, hereinafter referred to as the Pan Township) were initially observed. The result is as follows. 1 Experimental Methods 1.1 New Infant Infection Survey The infants born locally from April 1986 to February 1987 were screened twice a week during the season of malaria onset. They were screened for passive surveillance during the suspended period of dissemination and observed continuously for one year. Record whether the history of going out. Where there are symptoms of fever for blood tests, found that Plasmodium positive local infants infected, calculate the incubation period.
