What is Japanese encephalitis?

Japanese encephalitis is the full name of epidemic encephalitis B, also known as Japanese encephalitis, which is an acute infectious disease of the central nervous system caused by the Japanese encephalitis virus. Mosquitoes are the vectors of this disease, among which Culex tritaeniorhynchus is the main vector of Japanese encephalitis in China .

The epidemic of Japanese encephalitis has obvious seasonality, mainly concentrated in July to September . The general population is susceptible to Japanese encephalitis. With the widespread vaccination of Japanese encephalitis vaccine, the incidence of Japanese encephalitis in our province has dropped to a low level .

What are the symptoms of infection with Japanese encephalitis virus?

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.
