The natural history of psoriasis was studied through a questionnaire survey of 5,600 patients throughout the United States. The mean age of onset of psoriasis was 27.8 years. 36% of the respondents reported familial occurrence of the disease. At the time of study, the lower extremities were indicated as being the most often affected; trunk, elbow, and scalp were next, knee and face were cited less frequently. Fingernails were involved in half of the patients at some time during the period of their disease. In the majority of patients, hot weather and sunlight had a beneficial effect. One third of the females also indicated improvement during the course of pregnancy. Remissions were reported in 39% of the patients.

“…In Africa, variations in the prevalence of psoriasis have been observed between West African countries such as Nigeria (0.8%) and East African countries such as Kenya (2.6%). 8,9 It is unclear if these observed variations are caused by genetic or environmental differences or because of bias in the study designs. Our findings confirm previous investigations that have suggested that psoriasis is less common in African Americans than in Caucasians.…”

“…Locations of reported skin disease surveys in sub-Saharan Africa. Data on the incidence of skin diseases are reported from clinics at z locations in Saharan or Mediterranean Africa (i, 2) and from 16 locations in sub-Saharan Africa (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) comparable conditions of access to medical treatment occur, may reveal differences in prevalence between populations (whenever possible, an adjusted psoriasis incidence rate is calculated to reflect the proportion of new skin patients with non-infectious skin disorders). Thus, the comparatively low incidence rates at clinics in Nigeria, Senegal, and Mali (see below) in western Africa may reflect the lower prevalence of psoriasis in these countries.…”
