A novel, synthetic DNA vaccine developed at the Wistar Institute induces protective immunity against Mayaro virus (MAYV), a mosquito-borne infection endemic to South America, that has the potential to become a global emerging viral threat.
Mosquitoes of the genus Anopheles are well known as primary vectors of malaria. But a new study suggests that Anopheles species, including some found in the US, are capable of carrying and transmitting an emerging pathogen, Mayaro virus, which has caused outbreaks of disease in South America and the Caribbean.
Research findings suggest the presence of highly endemic foci of Mayaro virus in central Brazil.
There are a number of emerging diseases on which experts are keeping a close eye.
