Nonarboviral Encephalitis

Nonarboviral encephalitis is a condition that causes swelling of the brain. It has many causes, but most cases are due to a virus. The illness can spread in different ways. Some ways include from person to person, contaminated food or surfaces, or from certain animals to humans. Symptoms occur when an organism or agent invades and multiplies in a person's central nervous system (brain or spinal cord).

The illness can be caused by various infectious agents. Some include bacteria, viruses, fungi, protozoans, and other parasites. Common viruses include the herpes virus, enterovirus, mumps, measles, and varicella. It is very rare for the condition to happen after a person receives a vaccine. In those cases, symptoms may be from an allergic reaction rather than from active infection.
