Global travel exposes many people to a range of health risks. Many of these risks can be minimized by precautions taken before, during and after travel. International Travel and Health (ITH) is a guide for medical and public health professionals who provide advice to travelers.

Mass gatherings are events attended by a sufficient number of people to potentially strain the public health resources of a community, state or nation. The mass gatherings program provides guidance to countries hosting events that will draw unusually high numbers of people.
