Global TravEpiNet (GTEN) (GTEN) is a national network of clinics across the United States that aims to improve the health of those who travel internationally, including travelers with higher risk for illness or injury while abroad. High-risk travelers can include those visiting friends and relatives (VFRs), students studying abroad, the very young, the very old, and travelers with immunosuppressive conditions.



GeoSentinel is a worldwide data collection and communication network for the surveillance of travel-related morbidity. It was initiated in 1995 by the International Society of Travel Medicine (ISTM) and CDC and is composed of ISTM-member travel and tropical medicine clinics.
