Coccidioidomycosis in Latin America

Area of Science:

• Mycology
• Infectious Diseases
• Epidemiology

Background:

• Coccidioidomycosis is a prevalent systemic fungal infection in Latin America, with reported cases across multiple countries.
• Its incidence is underestimated due to limited clinical awareness and diagnostic capabilities.
• The infection is as common in Mexico as in endemic US regions, with increasing reports in Brazil and Argentina.

Purpose of the Study:

• To summarize the epidemiology and diagnostic challenges of coccidioidomycosis in Latin America.
• To identify the prevalent etiological species and discuss co-infections.
• To highlight diagnostic methods and the underdiagnosis of primary disease.

Main Methods:

• Literature review of coccidioidomycosis in Latin America.
• Analysis of genetic studies identifying Coccidioides species.
• Review of diagnostic approaches and co-infection patterns.

Main Results:

• Coccidioides posadasii is the predominant species in Latin America; Coccidioides immitis is rare.
• Co-infection with tuberculosis is noted due to shared risk factors like immunosuppression.
• Diagnosis often relies on sputum examination and histopathology, leading to underdiagnosis of primary coccidioidomycosis.

Conclusions:

• Coccidioidomycosis is a significant public health issue in Latin America requiring improved diagnostics.
• Understanding species prevalence and co-infection risks is crucial for effective management.
• Further research is needed to accurately determine incidence and improve early detection strategies.
