Advice For Travellers

While the total number of reported cases is not large, they do indicate that this virus is circulating in the affected areas. The risk for general travellers can vary depending on their activities in the affected area. Travellers to areas where this virus is circulating can reduce their risk of exposure to Japanese encephalitis virus by taking all necessary precautions to avoid mosquito bites. Vaccination against Japanese encephalitis is recommended, especially if visiting rural rice growing areas.
