Since then, it has had “limited circulation” in regions of South America, particularly in forested areas, according to the CDC.The disease is typically spread through bites from mosquitoes and midges (small flies, particularly the Culicoides paraensis species). Three-toed sloths and birds have been identified as “natural reservoirs” for the Oropouche virus, which means they act as hosts of the disease.
