Skin disease in rural Tanzania

Skin disease is a common problem, accounting for significant morbidity in developing countries. Knowledge about the prevalence of different skin conditions allows appropriate planning for provision for these health needs. There are currently few data about the needs in rural areas; therefore, this study was set up to investigate skin abnormalities found in a village population in Tanzania.

A village with a population of 2,876 was chosen and one-third of the population was examined for cutaneous abnormalities.

During the survey, 97.7% of the target population was examined. Signs of nutritional deficiency were common with koilonychia affecting 18.1% of the population examined and signs of hypoproteinemia being present in 3.4% of them. Infections and infestations were also frequently seen. Scabies was observed in 6.0% and pediculosis capitis in 5.3%. Dermatophyte infection was present in 5.1%. These were all most common in prepubertal children. Leg sores were seen in 5.1% and leg ulcers in 3.0% of the population.

The survey reveals that easily treatable skin infections and infestations are common in a rural Tanzian population. Signs of nutritional deficiency are also frequently seen.
