Viral Encephalitis is a symptom caused by arthropod-borne viruses also known as arboviruses. These viruses, belonging to the Togaviridae, Flaviviridae, and Bunyaviridae families, are zoonoses - animal infections that can spread to humans - that are transmitted by mosquitoes, ticks, moth flies, and sand flies who feed on mammals and birds Although bacterial, fungal, and autoimmune disorders can produce encephalitis, most cases are viral in origin.
