GeoSentinel is a worldwide communication and data collection network for the surveillance of travel related morbidity.   It was initiated in 1995 by the International Society of Travel Medicine (ISTM) and the Centers for Disease Control (CDC) as a network of ISTM member travel/tropical medicine clinics.  GeoSentinel is based on the concept that these clinics are ideally situated to effectively detect geographic and temporal trends in morbidity among travelers, immigrants and refugees.

Current activities include:

GeoSentinel Surveillance Sites GeoSentinel Network Members

GeoSentinel Sites participate in surveillance and monitoring of all travel related illnesses seen in their clinics.  Aggregation of this data across the network of 57 globally dispersed medicine clinics on all continents allows linking of final diagnoses in migrating populations with similar geographic exposures.  In addition to formal surveillance, GeoSentinel sites also participate in enhanced surveillance and networking with public health partners.

GeoSentinel Network Members are ISTM provider clinics that informally provide leads and contacts when they encounter any patient having a pre-defined alarming diagnosis or unusual event.  Network Members also participate in brief e-mail queries for enhanced surveillance and response in potential outbreak situations.  This program allows large numbers of individual members in many countries to be rapidly linked together to share clinical observations and facilitates direct interaction with health authorities.
