In Montgomery County (1990 population: 209,085), Alabama, an epidemic of early syphilis (ES) (i.e., primary, secondary, and early latent) involving 1010 cases occurred from August 1990 through November 1991 (Figure 1). From June 17 through November 7, 1991, the Alabama Department of Public Health (ADPH) and CDC initiated an intervention campaign to reduce the incidence of ES; the intervention increased case-finding primarily through partner notification (PN) and cluster investigations.* This report assesses the intervention campaign by describing 1) the results of PN/cluster investigation interviews during the intervention, 2) the relation between reported crack cocaine use and PN/cluster investigation results, 3) a comparison of interview results for the first 6 weeks of the campaign (i.e., early campaign period) with the 6-week period immediately before the campaign (i.e., precampaign period), and 4) the syphilis morbidity trends for 1990 and 1991.
