Overview

Encephalitis is an acute inflammation of the brain, commonly caused by a viral infection. Sometimes, encephalitis can result from a bacterial infection, such as bacterial meningitis, or it may be a complication of other infectious diseases like rabies (viral) or syphilis (bacterial). Certain parasitic or protozoal infestations, such as toxoplasmosis, malaria, or primary amoebic meningoencephalitis, can also cause encephalitis in people with compromised immune systems. Brain damage occurs as the inflamed brain pushes against the skull, and can lead to death.

Primary Prevention

• Post-infectious encephalomyelitis complicating small pox vaccination is totally avoidable now as small pox is now eradicated. Contraindication to Pertussis immunisation should be observed in patients with encephalitis. An immunodeficient patient who have had contact with chicken pox virus should be given prophylaxis with hyperimmune zoster immunoglobulin.
• Practice good hygiene
• Avoid sharing utensils
• Get vaccinations
• Protection against mosquitoes and tick bites (dress to protect yourself, apply mosquito repellent, use insecticides, prevent stagnation of water)
