An outbreak of syphilis in Alabama prisons: correctional health policy and communicable disease control.

OBJECTIVES: After syphilis outbreaks were reported at 3 Alabama State men's prisons in early 1999, we conducted an investigation to evaluate risk factors for syphilis infection and describe patterns of syphilis transmission. METHODS: We reviewed medical, patient interview, and prison transfer records and documented sexual networks. Presumptive source cases were identified. Odds of exposure to unscreened jail populations and transfer from other prisons were calculated for case patients at 1 prison. RESULTS: Thirty-nine case patients with early syphilis were identified from 3 prisons. Recent jail exposure (odds ratio [OR] = 8.0, 95% confidence interval [CI] = 0.3, 158.7, P = .14) and prison transfer (OR = 32.0, 95% CI = 1.6, 1668.1, P < .01) were associated with being a source case patient. CONCLUSIONS: Probable sources of syphilis introduction into and transmission within prisons included mixing of prisoners with unscreened jail populations, transfer of infected inmates between prisons, and multiple concurrent sexual partnerships. Reducing sexual transmission of disease in correctional settings is a public health priority and will require innovative prevention strategies.

Urine-based screening of adolescents in detention to guide treatment for gonococcal and chlamydial infections. Translating research into intervention.

OBJECTIVES: To determine the utility of urine-based ligase chain reaction assays for Neisseria gonorrhoeae and Chlamydia trachomatis in (1) the acceptability of such testing to adolescent detainees, (2) the potential use of these tests for identifying asymptomatic infections, and (3) the effectiveness of this approach for ensuring treatment of infected adolescents. DESIGN: Cross-sectional screening and verification of treatment for infected cases. SUBJECTS: Adolescents admitted to a short-term juvenile detention center. MAIN OUTCOME MEASURES: Neisseria gonorrhoeae and C trachomatis infection rates, and timing and location of treatment for infected patients. RESULTS: Refusal rate was 1.5%. Of 263 participants, 46 (17.5%) were female subjects. Chlamydia trachomatis infections were identified in 28.3% of the female and 8.8% of the male subjects. Neisseria gonorrhoeae infections were present in 13.1% of the female and 2.8% of the male subjects. Overall, 37 participants (14%) were positive for N gonorrhoeae, C trachomatis, or both, only one of whom had symptoms. Almost 70% (25/36) of asymptomatic infected subjects were treated within 28 days of screening. A treatment was documented in 36 of the 37 infected youth, including 20 who were followed up and treated after release from the detention center, by 6 months after testing. CONCLUSION: Urine ligase chain reaction tests were effective for identifying and guiding treatment of unsuspected N gonorrhoeae and C trachomatis infections in teenagers admitted to a short-term detention center where traditional swab specimens may be difficult to obtain.

Control of epidemic early syphilis: the results of an intervention campaign using social networks.

BACKGROUND: During an epidemic of early syphilis, social networks were used for an intervention campaign. GOAL OF THIS STUDY: To characterize the epidemic and describe the yield of new cases from index-case interviews. METHODS: Analyses of morbidity data collected by the Montgomery County, Alabama, sexually transmitted disease program determined the course of the epidemic and characterized the new case yields from social networks identified via index-case interviews (partner notification investigations) and interviews with sex partners and their associates (cluster investigations). Results and costs were compared to a noncampaign period. RESULTS: The number of reported syphilis cases nearly doubled from 1990 to 1991 (201 to 348 per 100,000 residents). During the 21-week campaign, 373 case-patients had partner notification/cluster investigations; 113 (11%) of 984 sex partners and 41 (3%) of 1,146 high-risk associates (persons identified during cluster investigations) had syphilis. No subgroup of case-patients for which the partner notification/cluster investigation yielded more infected persons than other subgroups was identified. The cost per case detected was more than twice that during a noncampaign period ($1,627 vs. $771). CONCLUSION: Partner notification investigations yielded more infected persons than cluster investigations. Further evaluation is needed to determine the role of intense partner notification/cluster investigators' efforts in the control of epidemic syphilis.
