Fungal Infections and Studies

There is currently an epidemic of tinea capitis in urban areas of developed countries caused by Trichophyton tonsurans. Recurrence or re-infection with dermatophyte is not uncommon after adequate oral treatment. Asymptomatic carriers who are household contacts may partly explain this observation by forming a reservoir for infection.Two-hundred and nine household contacts of patients with tinea capitis were examined and screened for asymptomatic carriage of dermatophyte.Only 7.2% had clinically evident disease yet 44.5% had silent fungal carriage on the scalp. Children under 16 years were much more likely to be carriers than adults (P < 0.001) and males were less likely than females to be affected (P < 0.01).This evidence poses questions about factors relevant in transmission of dermatophytes. The authors propose that all household contacts of patients with tinea capitis should be offered screening to eradicate a potential reservoir of infection.
