Arboviruses: variations on an ancient theme

Genetics of War and Truce between Mosquitos and Emerging Viruses

Arboviruses have made unexpected reappearances in recent years. Unlike viruses that undergo direct transmission, arboviruses utilize an arthropod vector (e.g., mosquitos, sandflies, and ticks) to spread throughout human populations. Here, we provide a snapshot of mosquito susceptibility to viral infection using flaviviruses, alphaviruses, and bunyaviruses as examples of emerging pathogens of global health relevance.
