Abstract:

The habitats of Biomphalaria straminea，the intermediate host of Schistosoma mansoni，have been found in Hong Kong Special Administrative Region and Shenzhen City of People’ s Republic of China. Currently，there is a sharp increase in the number of Africa?aid projects and workers moving to Africa，and more and more cases infected with S. mansoni or S. haematobium returning from African countries have been detected in China. The possibility of transmission of African schistosomiasis in Chinese mainland，in the context of global climate warming，has received much attention. This paper illustrates the risk of transmission of African schistosomiasis in China based on biological and epidemiological features， and proposes interventions to tackle the risk.

摘要：

中国香港和深圳地区相继出现曼氏血吸虫中间宿主—藁杆双脐螺孳生地； 在我国援非项目和赴非务工人员数量剧增的同时， 赴非洲回国人员中感染曼氏或埃及血吸虫的报道亦逐渐增多； 在全球气候持续变暖的大环境下， 非洲血吸虫病会否在中国境内传播或流行， 再度引起了广泛关注。本文从生物学和流行病学角度， 就其传播风险作一剖析， 并提出相关应对措施。
