Case report describes rhodesiense sleeping sickness in U.S. traveler returning from Zimbabwe

This is a descriptive case report of a single patient: a U.S. traveler returning from Zimbabwe diagnosed with rhodesiense human African trypanosomiasis (sleeping sickness). The report describes 1 case. No details are provided regarding the specific intervention or exposure, comparator, treatment course, or clinical outcomes. Safety and tolerability information is not reported. The follow-up duration is also not reported.

Key limitations are inherent to the study design. This is a single case report without a control group, comparative data, or statistical analysis. No causal inferences, effect sizes, or measures of efficacy or safety can be drawn. The findings cannot be generalized to other populations.

Regarding practice relevance, this report solely documents the occurrence of a rare, imported parasitic infection. It does not provide evidence to guide diagnosis, treatment, or prevention. Clinicians should be aware that rhodesiense sleeping sickness can occur in travelers from endemic regions like parts of Zimbabwe, but this report offers no comparative or outcome data to inform management.
