The natural reservoir of Mayaro virus includes which of the following?

The key idea is identifying who actually maintains the virus in nature. Mayaro virus is kept in a sylvatic cycle primarily between non-human primates and forest-dwelling mosquitoes. Humans typically become infected only as spillover hosts when they enter or near forested areas; they are not the natural reservoir. Domestic pigs and rodents are not recognized as the main reservoirs for Mayaro, and while other vertebrates can be exposed, the primates are the primary reservoir species. That’s why the option naming non-human primates as the reservoir best fits, even if birds and reptiles may occasionally be involved in broader transmission scenarios.
