Dermatophytoses, particularly tinea capitis and tinea unguium, were common in Cusco, Peru, affecting young individuals. Microsporum canis was the most frequent pathogen, with environmental factors like altitude not hindering infection spread.

Area of Science:

  • Mycology
  • Dermatology
  • Infectious Diseases

Background:

  • Dermatophytoses are superficial fungal infections affecting skin, hair, and nails.
  • Understanding the epidemiology of these infections is crucial for public health interventions.
  • High-altitude environments may influence the prevalence and types of dermatophyte infections.

Purpose of the Study:

  • To investigate the prevalence and etiological agents of suspected dermatophytoses in Cusco, Peru.
  • To identify the most common clinical types and causative fungal species.
  • To assess the influence of environmental factors on dermatophyte infections in this region.

Main Methods:

  • A prospective study observed 90 cases of suspected dermatophytoses over nine months.
  • Clinical diagnoses included tinea capitis and tinea unguium.

  • Fungal isolates were identified to the species level.

    • Main Results:

    • The most affected age groups were 1-10 and 11-20 years old.
    • Tinea capitis (13.3%) and tinea unguium (11.1%) were the most diagnosed conditions.
    • Microsporum canis (52.4%) was the predominant dermatophyte, followed by Trichophyton mentagrophytes (35.7%).

    Conclusions:

    • Dermatophytoses are prevalent in Cusco, with a predilection for younger populations.
    • Microsporum canis is the primary etiological agent in this Peruvian setting.
    • Environmental factors such as dry weather, low temperature, and high altitude did not appear to impede dermatophyte proliferation or infection.
