The Centers for Disease Control and Prevention (CDC) Yellow Book is the recommended resource for information specific to illnesses associated with a returned traveler. Visit the Yellow Book for general information on how to approach travel-related health problems.
As many as 43%–79% of travelers to low- and middle-income countries become ill with a travel-associated health problem. Although most of these illnesses are mild, some travelers become sick enough to seek care from a health care provider. Most post travel infections become apparent soon after returning from abroad, but incubation periods vary, and some syndromes can present months to years after initial infection or after travel. Additional resources for evaluating a returned traveler can be found here.
lllnesses associated with fever appearing in the first two weeks after travel
| Syndrome | Possible Cause |
|---|---|

The Yellow Book covers common travel-related health problems, including fever in returned travelers, persistent travelers’ diarrhea, skin/soft tissue infections , and advice on screening asymptomatic returned travelers.
