Vaccination Prevents Japanese Encephalitis
Medical authorities are advising travelers to Asia–and Southeast Asia in particular–to consider being vaccinated against Japanese encephalitis, a mosquito-borne viral infection. The vaccine isn’t suitable for everyone, but should be considered by travelers who plan an extended stay or will spend time in rural areas. Approximately 30,000 to 50,000 cases of Japanese encephalitis are reported annually. Only about one in 250 cases of infection develops into encephalitis, and fatalities are most often among young children, the elderly and those with compromised immune systems.
