Advice For Travellers

Because it is unclear how many of these cases of encephalitis are actually due to infections with the Japanese encephalitis virus, it is difficult to judge the risk of exposure for travellers in these regions. However, all travellers can reduce their risk of exposure to Japanese encephalitis virus by taking all necessary precautions to avoid mosquito bites. Vaccination against this virus is recommended for persons visiting the areas noted in this alert where this virus may be active.
