Endemic pyoderma in Ghana: a survey in rural villages

Abstract

The prevalence and characteristics of pyoderma in a randomly sampled rural population in Ghana has been studied. Findings are compared with studies reported in recent literature which describe pyoderma in other countries. In the present study, conducted in 1975 as part of the Danfa Project's Village Health Survey, pyoderma was diagnosed in 19.4% of villagers examined. Peak rates occurred in the five to nine-year-old age group, and pyoderma was more prevalent among males and unskilled labourers and farmers than among those engaged in more sedentary occupations. Non-bullous impetigo was most common (72% of lesions) and, in contrast to other studies, non-group A-streptococci predominated in these lesions (82% of streptococcal lesions were Group G, 18% Group C). Current knowledge of transmission and control of pyoderma is discussed.
