Japanese encephalitis kills 10 children in Son La Province, Vietnam

A Japanese B encephalitis outbreak, involving 84 cases and 10 deaths (all children), has been reported in Son La province. Short-term travellers and those who restrict their visits to urban areas are generally at very low risk. Those at higher risk are travellers who visit or work in rural agricultural areas such as rice fields and marshland. Long-term travellers and expatriates are also at higher risk. Travellers 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 for people who may be at risk.
