Holy shit, if this pans out that would be *amazing*.
The tldw is that when mosquitos take a blood meal from someone on ivermectin, ~50% of the mosquitoes just... die within 2 days, and none of the mosquitos laid eggs. There's also some (conflicting) indications that it inhibits plasmodium reproduction. (y'know, the parasite that causes malaria) Plus ivermectin's cheap and generally safe.
Current modeling says 3 doses over 3 months could reduce new malaria cases by 71%.
