The changing pattern of Tinea capitis in Jamaica

Area of Science:

• Medical Mycology
• Dermatology
• Infectious Diseases

Background:

• Tinea capitis, a fungal infection of the scalp, is caused by dermatophytes.
• The etiological agents of tinea capitis exhibit geographical and temporal variations.
• Understanding local fungal prevalence is crucial for effective treatment strategies.

Purpose of the Study:

• To identify the predominant dermatophyte species responsible for tinea capitis in Jamaica.
• To track changes in fungal epidemiology over a five-year period.

Main Methods:

• Retrospective analysis of fungal culture requests from January 1, 1998, to December 31, 2002.
• Data collected from the Microbiology Department at the University Hospital of the West Indies.
• Identification of dermatophyte species from positive fungal cultures.

Main Results:

• A significant epidemiological shift was observed in tinea capitis causative agents.
• Microsporum audouinii was dominant in 1998 (61.5%).
• Trichophyton tonsurans became dominant by 2002 (85%).
• The mean age of affected individuals was 8.6 years.
• Females represented 55.7% of positive cases, and males 44.3%.

Conclusions:

• The study highlights a dynamic change in the predominant dermatophytes causing tinea capitis in Jamaica.
• Trichophyton tonsurans has emerged as the primary pathogen.
• These findings underscore the need for ongoing surveillance of fungal infections.
