Severe Infections in Returning Travelers.

In an increasingly globalized world, it is of paramount importance to be aware of infections that can be contracted during travel-related activities as 43% to 79% of travelers specifically to low-middle income countries return with severe illness. Using a standardized approach to the evaluation of a returning traveler is of utmost importance in developing an appropriately broad differential diagnosis. This includes a thorough travel history paired with an accurate timeline of symptoms all in context of geographically specific risks of infection. Malaria, dengue, and enteric fever are among the most commonly diagnosed travel-related infections.
