fever in travelers
- related: Infectious Disease
The differential diagnosis for fever in a returning traveler depends on geographic epidemiology and is often divided into 3 categories (with some overlap):
- Early incubation period (<10 days) infections include typhoid fever, dengue fever, chikungunya, influenza, and legionellosis
- Medium incubation period (1-3 weeks) infections include malaria, typhoid fever, leptospirosis, schistosomiasis, and rickettsial disease
- Longer incubation period (>3 weeks) infections include tuberculosis, leishmaniasis, and enteric parasitic infections.
