Effect of prolonged dehydration stress on the vector competence of <i>Aedes aegypti</i> for Mayaro virus.

ABSTRACT: Aedes aegypti is a competent vector for a variety of mosquito-borne viruses including Zika, chikungunya, Mayaro, yellow fever, and dengue, which cause debilitating diseases in animals and humans. It is highly invasive and is widely distributed across Asia, Europe, Oceania, and the Americas. Climatic factors such as relative humidity (RH) can have substantial effects on mosquito biological characteristics and the dynamics of pathogen spread. Low RH leads to dehydration in mosquitoes causing modifications in behavioral and physiological responses pertaining to pathogen spread, such as host-seeking behavior and blood-feeding patterns. Here, we evaluated the effects of prolonged dehydration stress on Mayaro virus infection and vector competence in Ae. aegypti mosquitoes. Our find
