Mayaro virus (MAYV; family Togaviridae, genus Alphavirus) is an emerging global threat that can cause severe clinical manifestations similar to Zika, dengue, and chikungunya viruses. Currently, there is a lack of molecular tools to enable a better understanding of the transmission and pathogenesis of MAYV. Here, we detail the development and characterization of infectious clones of two strains of MAYV that produce infectious virus and replicate in mammalian and mosquito cells similarly to wild-type virus. Additionally, clone-derived viruses produced identical infection rates and phenotypes in CD-1 mice compared to the parental strains. This infectious clone system will provide a resource to the research community to analyze MAYV genetic determinants of virulence, determine vector competence, and develop vaccines.
