Japanese B Encephalitis is spread by mosquitoes in parts of Asia. It is a serious infection of the brain and vaccination is advised for those travelling to risk areas who are unable to avoid mosquito bites, staying for long periods (e.g. more than 4 weeks) or those visiting rural areas. Vaccination can also be considered for those spending a shorter period of time in rice fields (where the mosquito vector breeds) or close to pig farming (a reservoir host for the virus) Japanese Encephalitis vaccine is over 90% effective. Japanese Encephalitis is spread by night-time biting mosquitoes and for added protection you should sleep under a mosquito net and wear a DEET based insect repellent on your skin if you are visiting rural areas.
Japanese B Encephalitis is present throughout the Indian subcontinent, South East and East Asia and the Pacific.
