Best Practices for Preventing the Spread of Ringworm (Tinea Infection)

Thorough hand washing is the most important prevention step for reducing transmission of ringworm infections. 1

Key Prevention Strategies

Hand Hygiene

• Proper hand washing technique:

  • Wet hands with clean running water (warm or cold)
  • Apply soap and lather well
  • Scrub all surfaces including backs of hands, between fingers, and under nails
  • Continue scrubbing for at least 20 seconds
  • Rinse well under running water
  • Dry using clean disposable paper towel or air dry
  • Do not dry hands on clothing 1

• When to wash hands:

  • Immediately after contact with infected individuals or animals
  • After handling contaminated items (clothing, towels, bedding)
  • Before eating or drinking
  • After removing soiled clothing or shoes 1

• Hand sanitizers:

  • Use only if soap and water are unavailable
  • Must contain at least 60% alcohol
  • Not effective when hands are visibly dirty
  • Apply to palm, rub hands together covering all surfaces until dry 1

Environmental Controls

• Laundry practices:

  • Wash potentially contaminated items in hot water
  • Use boiling water for laundry when possible
  • Iron clothing before wearing 2
  • Avoid sharing:
    • Bed linens
    • Towels
    • Clothing
    • Shoes 2

• For animal-related ringworm:

  • Designate specific areas for animal contact
  • Do not allow food in animal contact areas
  • Clean and disinfect animal areas regularly
  • Supervise human-animal contact, especially with children 1

Special Considerations

• High-risk populations requiring extra precautions:

  • Young children
  • Older adults
  • Pregnant women
  • Immunocompromised individuals 1

• School and public settings:

  • Display educational signs about hand washing
  • Provide accessible hand-washing facilities
  • Supervise children's hand washing
  • Keep infected animals in enclosed areas or under restraint 1

Common Pitfalls to Avoid

1. Inadequate hand washing - The most common mistake is not washing hands thoroughly enough or skipping hand washing after contact with potentially infected sources 1

2. Sharing personal items - Continuing to share towels, clothing, or bedding with infected individuals 2

3. Improper use of hand sanitizers - Relying solely on hand sanitizers when hands are visibly soiled 1

4. Delayed treatment - Failing to recognize and treat ringworm promptly, allowing for further spread 3

5. Misdiagnosis - Ringworm can mimic other skin conditions like eczema, leading to inappropriate treatment and continued spread 3

By implementing these preventive measures consistently, the risk of ringworm transmission can be significantly reduced in both household and public settings.
