Commonly known as the “CDC Yellow Book,” Health Information for International Travel is a guidebook published every two years for healthcare professionals who care for international travelers.

The 2020 version, released in June 2019, includes updates related to the following:

  • Information about providing travel healthcare using telemedicine
  • Legal issues relevant for clinicians caring for travelers
  • Updates regarding diagnostic testing for infectious diseases and updates related to antimalarial drugs
  • Information related to road traffic safety
  • Treatment in light of antimicrobial resistance

Although people are currently not doing much traveling, these travel-related guidelines are important to consider as people return to normal activities.

Materials in this section are updated as new information and vaccines become available. The Vaccine Education Center staff regularly reviews materials for accuracy.
