Japanese encephalitis is a mosquito-borne infection that leads to swelling of the brain. It can affect the central nervous system and cause severe complications, even death.
Japanese encephalitis is caused by a bite from a mosquito infected with the virus.
Factors that may increase your chances of Japanese encephalitis:
Living or traveling in certain rural parts of Asia—Outbreaks have occurred in China, Korea, Japan, Taiwan, and Thailand. These countries have controlled the disease through
vaccinations. Other countries that still have periodic epidemics include Vietnam, Cambodia, Myanmar, India, Nepal, and Malaysia.
Employment as a lab worker, which may result in exposure to the virus.
Symptoms of Japanese encephalitis usually appear 5-15 days after the bite from an infected mosquito.
