The inoculation of viruses into mosquito bite sites is an important and common stage of arbovirus infections. Dr. McKimmie and his colleagues show that inflammation at bite sites aids viral replication and dissemination in vivo, resulting in more severe infection. These findings define additional targets for post-exposure prophylactic intervention. Image credit: Marieke Pingen et al.
