Advice for Travellers

Scrub typhus is an infection caused by a rickettsia-like bacteria. The infection is transmitted by mites and rats or mice may act as reservoirs. Humans may become infected in areas where the mites and rodents are present, most often areas of low-lying scrub brush or transitional vegetation.

Travellers should be aware of the risk of scrub typhus in these popular tourist destinations, particularly those visiting rural areas who should avoid close contact with this type of vegetation. The skin should be protected with clothing (ideally permethrin treated) and DEET insect repellent on exposed skin.
