Endemic syphilis in the Bakwena Reserve of the Bechuanaland protectorate: a report on mass examination and treatment.

Abstract

A form of endemic syphilis exists in the Bakwena Reserve of the Bechuanaland Protectorate known by the local name of "dichuchwa". It is similar to bejel, njovera and the endemic syphilis reported elsewhere in the world. The Government of the Protectorate, with the assistance of WHO and UNICEF, began in November 1953 a mass campaign in the Reserve to control this disease and, at the same time, to study its epidemiological, clinical, social and therapeutic aspects. The seropositivity rate in the Reserve was found to be 37%.Dichuchwa is a childhood and family disease, usually spread non-venereally. The early lesions are similar to secondary lesions of sporadic venereal syphilis, and are often followed by tertiary lesions affecting mainly the skin, nasopharynx and long bones. Primary lesions are rare but may occur under certain epidemiological conditions if the inoculum is sufficiently large; thus a mother may develop primary sores on the nipples through suckling an infected infant. Lesions of the cardiovascular and central nervous systems and congenital syphilis are also rare. Superinfection of an already infected and allergic host is probably the chief reason for the frequency of the tertiary lesions.Treatment of the disease with penicillin is very effective, and the authors believe that mass treatment of cases and contacts combined with an improvement in the standards of hygiene could eradicate the disease.
