Reflections on travel-associated infections in Europe

Abstract

In The Lancet Infectious Diseases, Patricia Schlagenhauf and colleagues1 analyse travel-associated morbidity in 32 136 travellers presenting to European sites of the GeoSentinel Network with a post-travel illness over the period 2008–12. Knowledge about illness in travellers contributes to the understanding of disease epidemiology in our interconnected world. In addition to their own ill health, travellers serve as sentinels of infectious diseases; moreover, they can also transmit and disseminate infections.
