      AFRICAN LITERATURE REVIEW: Looking at about 120 papers from MEDLINE on asthma in Africa, the present authors found that asthma research is currently dominated by authors from South Africa, followed by authors from Nigeria, Tanzania, Ethiopia, Kenya, and The Gambia. Most are case studies, closely followed by cross-sectional studies, and then case-control studies. There have been very few cohort studies. Only a few studies use objective measures.
      PREVALENCE (AFRICA): Intercountry prevalence data are limited to the International Study of Asthma and Allergies in Childhood, in which seven African countries participated, including English-speaking regions (Ethiopia, 9.1%; Kenya, 15.8%; Nigeria, 13.0%; South Africa, 20.3%) and French-speaking regions (Algeria, 8.7%; Morocco, 10.4%; Tunisia, 11.9%). Symptom rates are lower than in industrialized countries, while only South Africa approaches rates found in the UK. The interpretation of these figures, however, is difficult; there might be an increase with gross domestic product and industrialization factors. Rural African regions always showed much lower asthma prevalence rates than urban areas. People living in rural grasslands rarely, if ever, suffer from allergic diseases and some do not even have a term to describe this condition.
