Rheumatoid arthritis in Lesotho : a clinical and epidemiological survey

Hospital- based surveys and the few population studies (one in West Africa and two in South Africa) on the pattern of rheumatoid arthritis in black African population groups have created the impression that the disease is rare here and generally runs a milder course.
