New edition of International Travel and Health book from WHO

International travel is undertaken by large, and ever increasing, numbers of people. More people travel longer distances and at greater speed than ever before; an upward trend that looks set to continue. Travellers are thus exposed to a variety of health risks in unfamiliar environments. Most of these risks, however, can be minimised by suitable precautions taken before, during, and after travel. Virtually any place in the world can be reached within 36 hours, less than the incubation period for most infectious diseases.
