摘要: Schistosomiasis vector snails are subjected to extreme seasonal changes, particularly in ephemeral rivers and lentic waterbodies. In the tropics, aestivation is one of adaptive strategies for survival used by times extremely high temperatures desiccation. Aestivation therefore plays an important role maintaining transmission schistosomiasis. This review assesses possible impacts climate change on temporal spatial distribution schistosomiasis-transmitting with special emphasis aestivation, discusses effect schistosome infection ability. The parasite development snails, as well physiological discussed reference schistosomiasis transmission. shows that schistosome-infected have lower rates during those survive manage get rid infection. general, snail ability poor chances diminish t...
