Advice for travellers
Japanese encephalitis (JE) is the most important cause of viral encephalitis in Asia. It usually occurs in rural or agricultural areas, often associated with rice growing and pig farming. JE virus is transmitted to humans through the bite of infected Culex mosquitoes, particularly Culex tritaeniorhynchus. Most JE virus infections are mild (fever and headache) or symptomless, but around 1 in 250 infections results in severe and potentially fatal disease characterised by rapid onset of high fever, headache, neck stiffness, disorientation, coma, seizures, spastic paralysis and death. The risk to short-stay travellers and those who confine their travel to urban centres and use insect bite avoidance measures is low. Expatriates, repeat travellers and travellers living for prolonged periods in agricultural areas where Japanese encephalitis is endemic or where seasonal epidemics occur should consult their travel health provider about recommendations for vaccination.
