Travel medicine resources for the primary care physician.

Emporiatrics, or travel medicine, is not a part of everyday medical practice for most physicians, but with the growth in both domestic and international travel it makes sense to be prepared when the need arises. A number of useful resources are available to help in providing travel medicine services for both occasional and frequent travelers in need of accurate information about travel and health. A most useful aspect of the resources reviewed here is that they can be ordered or used according to the travel medicine needs of particular patients.
