Encephalitis is acute inflammation (swelling up) of the brain resulting either from a viral infection or when the body's own immune system mistakenly attacks brain tissue. The most common cause is a viral infection. Encephalitis occurs in 1 in every 1,000 cases of measles. Encephalitis generally begins with fever and headache. The symptoms rapidly worsen and there may be seizures (fits), confusion, drowsiness and loss of consciousness and even coma. It is transmitted to humans through the bite of infected Culex species mosquitoes, particularly Culex tritaeniorhynchus.
