Advice For Travellers

Sitata is posting this report as a reminder to all travellers that now is the season for transmission of Japanese encephalitis virus in many countries in southeast Asia.

Short-term travellers and those who restrict their visits to urban areas are generally at very low risk. However, the risk varies according to season, destination, duration of travel, and activities. Vaccination is recommended for travellers with extensive outdoor exposure (camping, hiking, working, etc.) during the transmission season, particularly in endemic countries or areas where flooding irrigation is practised. Long-term travellers and expatriates are also at higher risk. All travellers can reduce their risk of exposure to Japanese encephalitis virus by taking all necessary precautions to avoid mosquito bites.
