Yaws and syphilis in the Garkida area of Nigeria.

Sixty-four (4.2%) cases of yaws and forty-one (2.7%) cases of syphilis were encountered during an epidemiological survey for filariasis in the mid-Hawal river valley. This finding is despite the official position that yaws has been eradicated in Nigeria. The focus of the disease was localised in four of the six villages that were surveyed in the Garkida area of the valley. The disease was more common among farmers than among occupational groups. Aspart from yaws, syphilis (2.7%) which is another treponematoid infection was also encountered during the filariasis survey. The present findings imply that there still exists a benign transmission of the disease in the area and unless an immediate and effective control programme is initiated, yaws may still become a very important disease in Nigeria. The epidemiological aspects and public health implication of treponematosis especially of yaws, in this area are discussed.
