How to prevent recurrence of Tinea pedis?
- Regular use of talcum powders to reduce humidity and maceration.
- Eradication of the organisms is essential to prevent reinfection, disinfection of shoes with 1 % 8-hydroxycholine sulfate, formaldehyde and/or the environment may be helpful.
- Frequent hosing of the floors of shower rooms and the sides of swimming baths does reduce the prevalence of dermatophytes on these surfaces.
