Predominance of as Agent of Dermatophytoses in Cape Verdean School-Age Children.

Dermatophytoses are infectious skin diseases of public health importance because of their transmissibility and high prevalence, especially among children. This is the first study aiming to estimate and report the burden of dermatophytoses on school-age children on the island of Santiago in Cape Verde, an African country that is an archipelago. A total of 249 students attending the afternoon shift of three elementary schools in the city of Achada Igreja were examined. Of these, 60 had suspected lesions of dermatophyte infection. However, from the samples collected from these 60 students, including hair, nails, and skin scrapings, only 18 dermatophyte isolates were obtained, corresponding to a point prevalence of 7.2%. Morphological species identification demonstrated three different species: , , and ; re-identification by sequencing the internal transcribed spacer (ITS) 1 and 2 regions of ribosomal DNA, and the 5.8S rDNA encoding gene (ITS-5.8S region), revealed as the most prevalent species, with only one case of . This is the first epidemiological data describing dermatophytoses and dermatophytes in Cape Verde among school-age children on one of the archipelago islands. It reinforces the need of using culture and accurate identification methodologies when gathering epidemiological data on dermatophytoses.
