[Clinical-epidemiological aspects of pityriasis versicolor (PV) in a fishing community of the semiarid region in Falcon State, Venezuela].
Between August 2001 and May 2002, the prevalence and several epidemiological and clinical characteristics of pityriasis versicolor (PV) were studied in 902 individuals aged two months- 60 years, 426 females and 476 males, from a fishery community of Río Seco, a semiarid region in the state of Falcon, north-western Venezuela. The overall prevalence of the disease was 15.52% (140/902). The frequency of infection was higher in females (65.7% vs. 34.3%), children under one year of age and adolescents (27.9% y 32.1%, respectively), and dark skin (67.9%). The most commonly affected anatomical areas were the face (57.9%) and thorax (27.1%). The most important clinical features of the disease were: hypochromic (91.4%), multicentric (73.6%), pruritic (92.9%), fine scaled (80.7%) and irregularly shaped borders (91.4%). On the basis of these results, the possible risk factors on transmission dynamic and maintenance of the disease endemically is discussed.
