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).
