Occupational risk of Histoplasma capsulatum exposure among field biologists in Ecuador: Evidence from skin testing and serology.

Forty-five percent of Ecuadorian field biologists show prior exposure to Histoplasma capsulatum, revealing significant occupational risk in endemic environments.

• Why it matters: Histoplasmosis is underreported in Ecuador despite its endemic status, and understanding occupational exposure is crucial for improving diagnosis, prevention, and health outcomes among at-risk groups.
• What they did: The study tested 46 workers using skin tests and serology, finding 21 with prior exposure indicated by skin reactivity and 3 with recent infections, despite no symptoms.
• The result: These findings underscore the need for enhanced surveillance, diagnostic capacity, and awareness to protect field biologists and address occupational health risks in resource-limited endemic settings.
