Arboviruses and Their Vectors

Authors: Zachary J. Madewell, PhD, MPH


Arthropod-transmitted viruses (arboviruses) pose important public health challenges worldwide, and continue to do so even while the world is contending with the 2019 coronavirus disease (COVID-19) pandemic. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spread by contact with respiratory droplets from infected individuals. Arboviruses pose a different threat to humanity because of their efficient transmission by our formidable health adversary, the mosquito. There is no evidence that mosquitoes are vectors for SARS-CoV-2 or the two structurally related viruses causing SARS or Middle East respiratory syndrome. There are >500 recognized arboviruses worldwide, 150 of which are known to cause human disease.1
