Mayaro-feaver

Mayoaro virus (MAYV), an alphavirus of the Togaviridae family, was isolated from infected humans in 1954 in the province of the same name on the island of Trinidad.

The disease is endemic in the Caribbean, Bolivia, northern Brazil (Amazon region), Suriname and Colombia. Recent outbreaks suggest that MAYV has spread to both tropical and temperate regions(Diagne CT et al. (2020).

Carriers are Haemogogus mosquitoes and the yellow fever mosquito Aedes aegypti. The animal reservoir is probably monkeys, birds, marsupials (Lang W et al. 2000).

Fever, headache, chills, joint pain with swelling of the joints, nausea and exanthema. The infectious disease heals without complications after 3-5 days.

In the absence of a licensed vaccine and clinically proven therapeutics against Mayaro fever, prevention focuses mainly on mosquito control in the home (Diagne CT et al. 2020).
