A sustainable solution for infectious-disease control

If these eggs reach areas of fresh water, hatch and find a snail, and then infect a human host, their complex life cycle is completed. Because of the parasite's requirement for snails as part of its life cycle, there is a long history of public-health interventions aimed at reducing the snail population. Furthermore, assessing Schistosoma infection is challenging because diagnostics are at present imperfect, and because seasonal variation and other complexities affect measurement. [...]the conditions that produced the results here might not be present elsewhere, underscoring the need to carry out further research in other settings before the approach can be scaled up. [...]will this intervention achieve high and sustained large-scale uptake in the real world?
