Appendix D: Essential Electronic Resources for the Travel Medicine Practitioner (online only)

Megan Crawley O’Sullivan


A variety of electronic resources is available for practitioners who provide pre- and post-travel medical care for international travelers. Checking >1 authoritative website on a specific issue is always recommended. Authoritative recommendations may contain some element of opinion, and some sites are updated more frequently than others. Please note that the list below provides a representative but by no means exclusive sampling of resources that may be useful to the travel medicine practitioner. Brief descriptions of selected websites have been included to highlight resources that may be of particular interest.


Electronic distribution lists use e-mail with or without a browser-based interface. Some lists are set up to provide information only. Others promote active discussion among members, whereby anyone who has joined a particular group can e-mail a posting to a central server, which is then disseminated to all members who have subscribed to the same list. On a moderated list, each posting is reviewed and accepted by a moderator or editor, while unmoderated lists disseminate each posting instantly to all other subscribers. TravelMed is an example of an unmoderated list, which focuses on issues related to the practice of travel medicine. CDC provides email updates on a variety of health topics, including travelers’ health.
