The arboviral encephalitides comprise several different families of arthropod-borne viruses (arboviruses) that cause encephalitis, which is an inflammation of the brain tissue in humans and vertebrate animals. The arboviruses are transmitted from one vertebrate host to another by insects, ticks, or other arthropods. The biology and behavior of the arthropods and vertebrate hosts greatly influence the ecology and epidemiology of these viruses. Monitoring for arboviral encephalitis involves the organized tracking of levels of virus activity, vector (pathogen-transferring agent) populations, and infections in vertebrate hosts, along with human cases, weather conditions, and other factors, to detect or predict changes in the transmission dynamics of the infection.
