What is Japanese Encephalitis?

Japanese Encephalitis is a potentially severe disease. It is caused by a virus spread by infected mosquitoes in Asia and the western Pacific. JE virus is one of a group of mosquito-transmitted viruses that can cause inflammation of the brain. Surviving JE sufferers may be left permanently disabled both physically and mentally. JE is caused by bites from Culex mosquitoes which carry the JE virus.

Vaccination and preventing mosquito bites are the only methods of protection. Wear Proper Clothing to Reduce Mosquito Bites. When weather permits, wear long sleeves, long pants, and socks when outdoors. Reduce Exposure to Mosquitoes During Peak Biting Hours. Japanese encephalitis virus cannot transmit from one person to another. JEV is related to the viruses that cause St. Louis encephalitis and Murray Valley encephalitis, West Nile virus, dengue fever, and yellow fever.

When mosquitoes infect an animal, the animal might become a carrier of the virus. When other mosquitos feed on these animals that have newly acquired the virus, they take it on board and infect other animals. People are at the highest risk in rural areas where the virus is common. Japanese encephalitis is common around towns and cities. It is more likely to affect children because adults in areas where the virus is endemic generally become immune as they get older.

It is the most common trusted Source throughout Southeast Asia. China, Korea, Japan, Taiwan, and Thailand have had outbreaks in the past, but they have mainly controlled the disease through vaccination. Vietnam, Cambodia, Myanmar, India, Nepal, and Malaysia still experience occasional epidemics Trusted Source.
