Abstract

A survey of Tinea capitis (TC) and Pityriasis versicolor (PV) was conducted among school children in Abakaliki, south eastern Nigeria using standard mycological techniques. Of the 500 children studied (290 males, 210 females; aged 7-17years), 312 were clinically diagnosed but mycological examination showed dermatophytes in 259 specimens, a TC prevalence of 51.8% (95% CI., 47.4-56.2%), and Malassezia species in 23 specimens, a PV prevalence of 4.6% (95% CI., 2.8-6.4%). Boys were significantly more infected with TC than girls (61.0%, 95% CI., 55.4-66.6% vs 39.0%, 95% CI., 32.4-45.6%) (χ=23.62, df=1, P<0.05) and children 9 years old and less, were significantly more infected (60.0%, 95% CI., 50.4-69.6%) (χ=12.98, df=2, P<0.05). Girls were significantly more infected with PV (8.1%, 95% CI., 4.4-11.8%) than boys (2.1%, 95% CI., 0.4-3.8%) (χ=9.96, df=1, P<0.05) and highest prevalence was among children 14-17years old (9.3%, 95% CI., 5.0-13.4). The rates of TC and PV increased with increase in the number of occupants per bedroom.
