Mayaro virus is transmitted by mosquitoes, making vector-borne transmission the key mechanism. The virus cycles between non-human primates and mosquito vectors in forested areas, and humans become infected when bitten by an infected mosquito. This is why the spread relies on a biting insect as the carrier, not by direct contact, airborne droplets, or through water. Direct contact with animals would require an other mode of spread, airborne transmission is not the route for Mayaro in natural settings, and there is no waterborne transmission pathway for this virus.
