Life cycle of flavivirus
Web1 day ago · Flaviviruses within the family Flaviviridae are a diverse genus of more than 70 viruses that can cause severe infections in humans and other mammals and have an increasingly broad geographic distribution. Most flaviviruses require a blood-sucking (hematophagous) arthropod to complete their life cycle and we, therefore, refer to them … WebThe entry of flaviviruses into the cells is a multi-step process which involves several host factors that trigger the uptake of the virus. The initial step in the virus life cycle is the ...
