Projected climate changes in the coming decades are expected to affect the prevalence and incidence of some human helminth infections.Nearly one-fifth of the way through the 21st century, humanity is confronted by the realities of a quickly changing climate: warmer temperatures, alterations in rainfall patterns and distributions, floods and droughts, and other extreme weather events.All of these changes are expected to intensify in the coming decades.In concert with other global trends relevant to populations affected by neglected tropical diseases (NTDs), including social determinants such as urbanization, conflict, human migrations, and economic shifts [1,2], climate change will play a significant role in determining the future viability of helminth species and the emergence or decline of human helminthiases.Still another factor will be ongoing global efforts to control or eliminate human helminthiases through mass drug administration (MDA), vector control, and the delivery of new-generation biotechnologies.Because worms exist in dynamic relationships with their environments and, for some, with snail intermediate hosts or insect vectors, the effects of climate change will vary by species and could be multidimensional in nature.In addition, climate change may act synergistically or competitively with the major social determinants highlighted above, as well as MDA.Schistosomiasis in Africa is an example of the complexities of climate change interacting with urbanization and M...
