Area of Science:
- Tropical medicine
- Infectious diseases
- Clinical diagnostics
Background:
- Eosinophilia is a common finding in travelers returning from developing countries.
- Identifying the cause is crucial for appropriate management.
Purpose of the Study:

- To suggest appropriate drug treatments for these conditions.
Main Methods:
- Review of literature on eosinophilia in returned travelers.
- Analysis of diagnostic criteria for common etiologies.
- Summary of evidence-based treatment recommendations.
Main Results:
- Helminth parasite infections are the most frequent cause of eosinophilia.
- Protozoal, bacterial, and fungal infections are uncommon causes.
