Tinea Infections Flashcards

Tinea: Concepts of Infection

General Definition of Tinea

  • Tinea is a general term referring to fungal infections of the skin.
  • Different types of Tinea are classified based on the area of the body affected.

Types of Tinea

  • Tinea Capitus (Scalp Ringworm):
    • Characterized by scaly, erythematous, and itchy patches on the scalp.
    • Can lead to hair loss and the development of bald spots.
  • Tinea Corporis (Body Ringworm):
    • Presents as a circular, itchy, erythematous, scaly rash.
    • Features inflamed, raised borders.
  • Tinea Cruris (Jock Itch):
    • Manifests as an itchy, erythematous rash in the groin and inner thigh area.
  • Tinea Pedis (Athlete’s Foot):
    • Causes itching, burning, and cracked skin, typically between the toes.
  • Tinea Unguium (Onychomycosis):
    • Results in thickened, discolored, and deformed nails.

Causes and Transmission of Tinea Infections

  • Direct Skin-to-Skin Contact:
    • Transmission occurs through physical contact with an infected individual.
  • Sharing Contaminated Items:
    • Examples include towels, combs, and brushes that harbor the fungus.
  • Contact with Contaminated Surfaces:
    • The fungus can survive on surfaces, leading to infection upon contact.
  • Contact with Infected Soil:
    • Rare route of transmission, but possible through direct contact with contaminated soil.

Prevention Strategies

  • Avoid Sharing Personal Items:
    • Do not share items like towels, clothing, and grooming tools.
  • Keep Skin Dry:
    • Especially in moist areas such as skin folds, groin, and feet, to prevent fungal growth.
  • Maintain Good Hygiene:
    • Regular washing and cleaning of the body.
  • Wear Loose-Fitting Clothes:
    • Allows for better ventilation and reduces moisture buildup.
  • Opt for Cotton Clothes:
    • Cotton is more breathable and helps to keep the skin dry.
  • Avoid Contact:
    • Minimize contact with infected people or animals to prevent transmission.

Treatments for Tinea Infections

  • Antifungal Medications:
    • Topical Creams and Lotions:
      • Applied directly to the affected area to kill the fungus.
    • Oral Treatments (Pills/Tablets):
      • Taken orally for more severe or widespread infections.
    • Shampoos:
      • Used for scalp infections (Tinea Capitus).
    • Nail Lacquers:
      • Applied to the nails for treating Tinea Unguium (Onychomycosis).
