After being bitten by a mosquito carrying the Japanese encephalitis virus, most people only develop asymptomatic latent infection, and the vast majority of adults can gain immunity as a result.

A small number of people develop the disease after an incubation period of about 10-15 days after being bitten by a mosquito. Symptoms vary in severity, with an acute onset, usually with sudden fever, nausea, vomiting, drowsiness, and headache . The condition worsens after two or three days, with symptoms such as coma, restlessness, convulsions, delirium, irregular breathing, and a stiff neck often occurring.

In extremely severe cases, death may occur due to cerebral edema, respiratory or circulatory failure.

In most cases, the symptoms gradually disappear within 7-10 days, but in a few severe cases, sequelae such as mental abnormality, intellectual impairment, aphasia, and limited limb movement may remain after recovery for varying lengths of time.
