Reported gonorrhea cases have declined since 2002. From 2002 to 2006, reported chlamydia fluctuated, impacted by the closing of certain screening programs.
To characterize STD clients who have repeat gonococcal or chlamydial (GC/CT) infections over a five-year period.
Medical records from 2002 –2006 from municipal STD clinics were analyzed to identify GC/CT cases. “Repeaters” were defined as persons with two or more infections within 31 days, and “non-repeaters” were persons with one GC/CT episode within the study period.
Among the six municipal STD clinics, 96,698 clients made 171,894 visits from 2002 to 2006. Among these clients, 3% (2,960/96,698) were repeaters with GC/CT infections and 23% (22,598/96,698) were non-repeaters. The median time between infections was 254 days (range 31-1672) for GC repeaters and 314 days (range 31-1719) for CT repeaters. Among GC repeaters 87% were male, 96% were non-Hispanic black (NHB) and the median age was 23 years. Of GC non-repeaters 72% were male, 92% were NHB and the median age was 24 years. Comparing CT repeaters, 69% were male, 92% were NHB and the median age was 21 years. Of CT non-repeaters 63% were male, 84% were NHB and the median age was 23 years. Among GC infections, males were 2.7 times more likely to be repeaters than non-repeaters (OR=2.7, CI=2.3 to 3.1). Of CT infections, males were 1.3 times more likely to be repeaters than non-repeaters (OR=1.3, CI=1.1 to 1.4).
Young minority males were more likely to have repeat GC/CT infections. The interval between repeat gonococcal infections was shorter than for repeat chlamydial infections.
Identifying the populations with repeat GC/CT infections to target prevention interventions to reach core transmitter networks.
