东台市属非恒定性疟区,1987年核准中华按蚊为唯一传疟媒介。60年代初和70年代初曾发生两次间日疟暴发流行。1991年6月经历了较长的梅雨期,7月初遭受了特大洪涝灾害,6～9月期间降水量达1482.8mm,平均气湿为84.17%,4～11月气温在10℃以上5～10月在18.2～26.8℃之间,如此气象条件造成了该市媒介按蚊的高密度,并呈现3个特点:1.消长曲线双高峰:受6月份梅雨影响,7月2日中华按蚊出现第一高峰,受7月11日前暴雨影响,雨期及雨后短期内密度下降,7月下旬起上升,8月份出现第二高峰;2.密度高:第一、二高峰猪舍密度为503只和553只/人工小时,是上年同期的4.26倍和
Dongtai City is a non-persistent malaria area, in 1987 approved Anopheles sinensis as the only transmission malaria vector. Two malaria outbreaks occurred in the early 1960s and early 1970s. June 1991 experienced a long period of plum rain, which suffered a catastrophic flood disaster in early July. During June to September, the precipitation reached 1482.8 mm with an average air humidity of 84.17%. From April to November, the temperature was above 10 ° C Month between 18.2 ~ 26.8 ℃, so the meteorological conditions caused by the city’s high density Anopheles media, and presents three characteristics: 1. Growth and decline of the peak double peaks: affected by the June rainy season, July 2 Anopheles sinensis appear The first peak was affected by the heavy rain before July 11, the density decreased in the short term after the rainy season and the rain, rose in late July and the second peak appeared in August; 2. The density was high: the first and second peak pigsty density was 503 And 553 / artificial hour, 4.26 times of the same period of last year
