Biological invasion is a matter of great concern from both public health and biodiversity perspectives. Some invasive snail species may trigger disease emergence by acting as intermediate hosts. The geographic distribution of depends on the presence of susceptible species of freshwater snails that support the parasite's transformation into infective stages. spp. have shown strong local and global dispersal capacities that may increase due to the global warming phenomenon and increases in the development of agricultural and water projects. Should intermediate hosts become established in new areas then this will create potential transmission foci. Examples of snail invasions that have had an impact on schistosomiasis transmission include the introduction of to Congo and to Egypt. The current spread of in China is causing concern and needs to be monitored closely. An understanding of the mode of invasion and distribution of these snails as well as their experimental susceptibility to will predict the potential spread of schistosomiasis. Here we review the invasion patterns of snails and factors that control their distribution and the impact that invasion may have on intestinal schistosomiasis transmission. In addition, we propose some possible surveillance responses for optimum control strategies and interventions. Whenever possible, swift action should be taken to contain any new occurrence of these intermediate snail hosts.
从公共卫生和生物多样性的角度来看，生物入侵是一个备受关注的问题。一些入侵性蜗牛物种可能作为中间宿主引发疾病出现。其地理分布取决于支持寄生虫转变为感染阶段的淡水蜗牛易感物种的存在。[蜗牛物种名称]已表现出强大的本地和全球扩散能力，由于全球变暖现象以及农业和水利项目发展的增加，这种能力可能会增强。如果中间宿主在新地区定殖，那么这将形成潜在的传播疫源地。对血吸虫病传播产生影响的蜗牛入侵实例包括[蜗牛物种名称]被引入刚果以及[蜗牛物种名称]被引入埃及。[蜗牛物种名称]目前在中国的传播令人担忧，需要密切监测。了解这些蜗牛的入侵模式、分布以及它们对[血吸虫物种名称]的实验易感性，将预测血吸虫病的潜在传播。在此，我们综述了[蜗牛物种名称]的入侵模式、控制其分布的因素以及入侵可能对肠道血吸虫病传播产生的影响。此外，我们提出了一些可能的监测应对措施，以制定最佳控制策略和干预措施。只要有可能，就应迅速采取行动遏制这些中间蜗牛宿主的任何新出现情况。
