  1. PFU Plaque-forming units
  2. Groups of mosquitoes were maintained at 20 °C for the indicated time periods (7 and 14 days post-infection, at which time points the infection rate (number of positive mosquitoes/number of blood-fed mosquitoes), the dissemination rate (number of mosquitoes with virus detected in legs/total number of infected mosquitoes and transmission rate (number of mosquitoes with virus detected in saliva/total number of mosquitoes with disseminated infection) were determined
