Pattern of reactive serological tests for syphilis in different population groups attending the University College Hospital Ibadan (1976-1985).

A review of the reactive serological tests for syphilis was carried out. An overall seroreactivity of 5.1% was obtained over the 10-year period reviewed. A subtle but steady rise in the incidence of syphilitic infections was noted, from 7 to 10 new cases per 1000 population between 1970 and 1975. The predictive characteristics obtained from the screening tests show that the tests are reliable diagnostic tests when the results are carefully interpreted, and the medical personnel can be alerted of the prevalence of syphilitic infections.
