High Frequency of Mayaro Virus IgM among Febrile Patients, Central Brazil

Abstract

Mayaro virus (MAYV), an Aedes mosquito–borne alphavirus, is endemic to Brazil and other South America countries. We investigated dengue- and chikungunya-negative febrile patients visiting rural areas near Goiânia, Goiás, and found a high proportion (55%) of MAYV IgM. Our findings suggest the presence of highly endemic foci of MAYV in central Brazil.
