Abstract
A few decades ago, travel medicine, or travel health as labelled by WHO, had to be developed from scratch as an interdisciplinary field to protect travelers from illness and accidents, and ultimately death. A variety of surveys have shed some light on travel health risks. However, much remains to be done to improve the reliability of the evidence on which advisors to travelers base their recommendations. Ongoing assessment and analysis with multicentre collaboration and modern tools to generate data are needed.
