Surveillance for schistosomiasis haematobium in the Republic of Malawi -Mass treatment and the effective prospect

在对马拉维高流行地区的居民进行大规模治疗后，我们确认了血血吸虫病的流行。2010年同地区总患病率为34.9%，男性为42.6%，女性为28.5%。我们对居住在这些地区的受试者进行了吡喹酮管理的大规模治疗。结果表明，大量使用吡喹酮后血吸虫病患病率明显下降，提示吡喹酮是控制血血吸虫病的重要对策。重要的是，感染的主要根源是接触被污染的水。村民们在日常生活中与淡水密切接触，洗澡、洗衣服、如厕、游泳和钓鱼。因此，接触淡水对村民的日常生活至关重要。

We confirmed the prevalence of schistosomiasis haematobium after mass treatment for the residents that lived in the high-prevalence regions in Malawi. Total prevalence was 34.9%, the prevalence of male was 42.6% and that of female was 28.5%, respectively at the same regions in 2010. We conducted mass treatment of praziquantel administration for the subjects that lived in these regions. It showed that the prevalence was significantly decreased after mass treatment of praziquantel and indicated that praziquantel administration was very important countermeasure for controlling schistosomiasis haematobium. It is still very important that the main root of infection is contacting contaminated water. And then the villagers have close contact with fresh water at their daily life for bathing, washing clothes, toileting, swimming and fishing. Therefore, contacting fresh water is essential for the villagers at their daily living.
