“…The data indicate that viable fungal conidia are present in the environment surrounding patients with tinea capitis and on a wide variety of inanimate objects. Fomites may be in part responsible for treatment failures and relapses that are observed following therapy [215,219].

“…When a child is found to have tinea corporis it may be prudent to examine for tinea capitis [215,219]. In North America, where T. tonsurans tinea capitis predominates, a Wood's lamp is not helpful in the diagnosis unlike those countries where M. canis or T. schoenleinii are seen more frequently.…”

Tinea capitis is a common dermatophyte infection of the scalp in children. Dermatophytes are classified into three genera; tinea capitis is caused predominantly by Trichophyton or Microsporum species. On the basis of host preference and natural habitat, dermatophytes are also classified as anthropophilic, geophilic and zoophilic. The etiological agents of tinea capitis usually fall in the first and last categories. In North America, tinea capitis is now predominantly due to Trichophyton tonsurans. During the past 100 years the most common North American organism for tinea capitis was initially Microsporum canis followed later by M. audouinii. In other parts of the world the epidemiology varies. Tinea capitis is generally observed in children over the age of 6 years and before puberty, with African Americans being the most affected group. Clinical presentations are seborrheic-like scale, 'black dot' pattern, inflammatory tinea capitis with kerion and tiny pustules in the scalp. The clinical diagnosis should be confirmed by mycological examination. Wood's light examination was of value in diagnosing tinea capitis due to M. canis and M. audouinii; however, it is not helpful in T. tonsurans tinea capitis. Asymptomatic carriers may be a significant reservoir of infection and spread of spores may also involve inanimate objects. Carriers may benefit from shampooing their hair. Treatment of tinea capitis requires an oral antifungal agent. The data from the use of terbinafine, itraconazole and fluconazole are promising and suggest that these agents have an efficacy similar to griseofulvin while shortening the duration of therapy. Both griseofulvin and the newer antimycotics have a favorable adverse-effect profile and are associated with high compliance.

“…Although direct transmission of infection through person to person contact is often difficult to show (14), intrafamilial outbreaks of T. tonsurans have occasionally been reported (4,6,13,18,26). Institutional outbreaks are rare and reports in the literature refer only to cases concern-Corresponding author.…”

A nosocomial outbreak of dermatophytosis caused by Trichophyton tonsurans var. sulfureum subvar. perforans is reported in a nursing home for the elderly. The outbreak affected six residents and persisted for nine months despite remedial medical and sanitary measures. In a survey designed to determine the potential role of fomites in disease transmission, 129 environmental sites were sampled. A high proportion (22.3%) of the samples yielded T. tonsurans, including samples from beds, floors, and washroom facilities. Methods for the control of dermatophyte outbreaks in chronic care institutions are discussed.
