Epidemiology of tinea capitis among school-age children in Meiganga, Cameroon

摘要

Tinea capitis (TC) commonly called scalp ringworm is a worldwide concern and a public health problem in Africa. This study aimed at determining the epidemiologic profile of TC among school-aged children in the savanna zone of Cameroon. All children present at school during this study period, August 2011-July 2012, were examined for signs suggestive of TC. Children not registered at school were excluded from the study. Pathologic specimens were taken from suspected head lesions and cultured. Amongst the 4601 children, average age 10.7 ±0.16 years, 377 presented with suggestive TC lesions giving a prevalence of 8.1%. The proportion of boys with TC was (63.7%) higher than in girls (36.3%) (P < 0.05). TC manifestations varied; small plaques of alopecia 59.26% were the most frequent. Communal living was the most incriminated risk factor. Three hundred and thirty six isolates were obtained in culture. The prevalence was significantly higher (P < 0.05) in age range between 8 and 12 years, followed by that between 13 and 15. The most prevalent isolate was T. soudannense 56.8%, followed by T. rubrum 29.2%. Only 6.0% of the isolates belonged to the genus Microsporum.
