摘要
目的:了解象山半岛中华按蚊传播疟疾潜势。方法:采用媒介能量调查方法计算中华按蚊叮人率、人血指数、叮人习性和预期传染期寿命等参数,再按照Carrett-Jones公式求取中华按蚊媒介能量和基本繁殖率。结果:中华按蚊基本繁殖率平均为1.22,其中7月份最高,为4.16。结论:虽然当地中华按蚊媒介能量和基本繁殖率全年接近1,但在特定时间段内,中华按蚊具有一定的疟疾传播能力,存在疟疾流行的可能。
Objective To understand the potential capacity of malaria transmission of anopheles sinensis in Xiangshan Peninsula.Methods An investigation method for capacity of local vector transmission was used for quantitative calculation of anopheles sinensis biting rate,human blood index,man-biting habit and expected life of infectivity,etc,and then the vector capacity and basic reproduction rate of anopheles sinensis was obtained according to the formula of CarrettJones.ResultsThe basic reproduction rate of local anopheles sinensis were 1.22 on average,with the highest of 4.16 in July.Conclusions Both vectorial capacity and basic reproduction rate of local anopheles sinensis were relative high,and the basic reproduction rate from July to September were higher than critical level,which indicated a relative strong malarial transmission capacity and outbreak of malarial disease.
