HIV Outbreak Control With Effective Access to Care and Harm Reduction in North Carolina, 2017-2018.

Objectives. To assess and control a potential outbreak of HIV among people who inject drugs in Western North Carolina.Methods. Disease intervention specialists offered testing for hepatitis B and hepatitis C, harm reduction materials, and linkage to care to 7 linked people recently diagnosed with HIV who also injected drugs. Contacts were offered the same services and HIV testing. HIV genotype analysis was used to characterize HIV spread. We assessed testing and care outcomes by using state surveillance information.Results. Disease intervention specialists contacted 6 of 7 linked group members and received information on 177 contacts; among 96 prioritized contacts, 42 of 96 (44%) were exposed to or diagnosed with hepatitis C, 4 of 96 (4%) had hepatitis B, and 14 of 96 (15%) had HIV (2 newly diagnosed during the investigation). HIV genotype analysis suggested recent transmission to linked group members and 1 contact. Eleven of 14 with HIV were virally suppressed following the outbreak response.Conclusions. North Carolina identified and rapidly responded to an HIV outbreak among people reporting injecting drugs. Effective HIV care, the availability of syringe exchange services, and the rapid response likely contributed to controlling this outbreak.

A Comparison of Syphilis Partner Notification Outcomes by Reported Use of Internet-based Apps to Meet Sex Partners in North Carolina, 2013-2016.

BACKGROUND: Partner notification services (PNS) remain the backbone of syphilis control. The popularity of Internet-based apps to meet sex partners among early syphilis (ES) patients may hinder the success of PNS if partners cannot be located. METHODS: We compared demographic and clinical characteristics between male ES patients indicating sex with men (MSM) and reported in North Carolina between 2013 and 2016 by reported use of an Internet-based app to meet sex partners (app user). We used multivariable log-binomial regression to assess the association between app usage and ES exposure notification of 1 or more sex partner. RESULTS: Among 3414 MSM ES patients, 58.6% were app users. App users were more frequently white (33.2% vs 27.3%; P = 0.003), younger (median, 28 years vs 30 years; P = 0.0002) and less frequently human immunodeficiency virus coinfected (54.1% vs 58.2%; P = 0.02) compared to non-app users. Overall, 94.9% of app users and 89.6% of non-app users reported 1 or more sex partner. App users reported 2.5 times more locatable and 2.7 times more unlocatable sex partners than non-app users. Similar proportions of app (23.6%) and non-app users (25.0%) reported only unlocatable partners (P = 0.4). App usage was not associated with ES exposure notification of 1 or more sex partner (adjusted risk ratio, 0.99; 95% confidence interval, 0.87-1.13). CONCLUSIONS: We observed no difference in the proportion of locatable partners or likelihood of notifying 1 or more sex partner of exposure among MSM ES patients, by reported use of Internet-based apps to meet sex partners. Partner notification services continues to be an important mechanism to locate and assure treatment for sex partners in this population.

Screening Yield of HIV Antigen/Antibody Combination and Pooled HIV RNA Testing for Acute HIV Infection in a High-Prevalence Population.

IMPORTANCE: Although acute HIV infection contributes disproportionately to onward HIV transmission, HIV testing has not routinely included screening for acute HIV infection. OBJECTIVE: To evaluate the performance of an HIV antigen/antibody (Ag/Ab) combination assay to detect acute HIV infection compared with pooled HIV RNA testing. DESIGN, SETTING, AND PARTICIPANTS: Multisite, prospective, within-individual comparison study conducted between September 2011 and October 2013 in 7 sexually transmitted infection clinics and 5 community-based programs in New York, California, and North Carolina. Participants were 12 years or older and seeking HIV testing, without known HIV infection. EXPOSURES: All participants with a negative rapid HIV test result were screened for acute HIV infection with an HIV Ag/Ab combination assay (index test) and pooled human immunodeficiency virus 1 (HIV-1) RNA testing. HIV RNA testing was the reference standard, with positive reference standard result defined as detectable HIV-1 RNA on an individual RNA test. MAIN OUTCOMES AND MEASURES: Number and proportion with acute HIV infections detected. RESULTS: Among 86,836 participants with complete test results (median age, 29 years; 75.0% men; 51.8% men who have sex with men), established HIV infection was diagnosed in 1158 participants (1.33%) and acute HIV infection was diagnosed in 168 participants (0.19%). Acute HIV infection was detected in 134 participants with HIV Ag/Ab combination testing (0.15% [95% CI, 0.13%-0.18%]; sensitivity, 79.8% [95% CI, 72.9%-85.6%]; specificity, 99.9% [95% CI, 99.9%-99.9%]; positive predictive value, 59.0% [95% CI, 52.3%-65.5%]) and in 164 participants with pooled HIV RNA testing (0.19% [95% CI, 0.16%-0.22%]; sensitivity, 97.6% [95% CI, 94.0%-99.4%]; specificity, 100% [95% CI, 100%-100%]; positive predictive value, 96.5% [95% CI, 92.5%-98.7%]; sensitivity comparison, P < .001). Overall HIV Ag/Ab combination testing detected 82% of acute HIV infections detectable by pooled HIV RNA testing. Compared with rapid HIV testing alone, HIV Ag/Ab combination testing increased the relative HIV diagnostic yield (both established and acute HIV infections) by 10.4% (95% CI, 8.8%-12.2%) and pooled HIV RNA testing increased the relative HIV diagnostic yield by 12.4% (95% CI, 10.7%-14.3%). CONCLUSIONS AND RELEVANCE: In a high-prevalence population, HIV screening using an HIV Ag/Ab combination assay following a negative rapid test detected 82% of acute HIV infections detectable by pooled HIV RNA testing, with a positive predictive value of 59%. Further research is needed to evaluate this strategy in lower-prevalence populations and in persons using preexposure prophylaxis for HIV prevention.

"No one's at home and they won't pick up the phone": using the Internet and text messaging to enhance partner services in North Carolina.

BACKGROUND: The Internet and mobile devices are increasingly used by men who have sex with men to find potential partners. Lack of partner information, besides e-mail addresses or user profiles, limits the ability to adequately perform partner notification by traditional means and test those at high risk. To streamline North Carolina Internet Partner Notification (IPN) services, University of North Carolina at Chapel Hill collaborated with the North Carolina Division of Public Health beginning in July 2011 to formalize state IPN and text messaging for partner notification (txtPN) policies and centralize notification practices by designating a single IPN/txtPN field coordinator within the University of North Carolina at Chapel Hill. METHODS: We compared the number of IPN and txtPN contacts initiated and their outcomes in July 1, 2011, to June 30, 2012, and compared with outcomes in January 1, 2010, to December 31, 2010, the year before the collaboration. RESULTS: Overall, 362 IPN contacts were initiated compared with 133 initiated in 2010. More than half (59.1%) were black; mean age was 28.8 years. Almost all were men who have sex with men (83.7%). Approximately two-thirds (n = 230; 63.5%) of contacts were successfully notified using centralized IPN. Seven new cases of HIV infection, 11 new cases of syphilis, and 19 known previous HIV-positive persons were identified. Text messaging for partner notification was used for 29 contacts who did not initially respond to traditional notification or IPN; 14 (48%) responded to txtPN in a median time of 57.5 minutes (interquartile range, 9-2708). CONCLUSIONS: Centralization of IPN services augmented partner detection of new HIV and syphilis diagnoses. Text messaging for partner notification represents a potentially effective method for augmenting traditional partner services. In addition, IPN and txtPN allow identification of HIV-infected persons in need of linkage to care.

Estimating populations of men who have sex with men in the southern United States.

Population estimates of men who have sex with men (MSM) by state and race/ethnicity are lacking, hampering effective HIV epidemic monitoring and targeting of outreach and prevention efforts. We created three models to estimate the proportion and number of adult males who are MSM in 17 southern states. Model A used state-specific census data stratified by rural/suburban/urban area and national estimates of the percentage MSM in corresponding areas. Model B used a national estimate of the percentage MSM and state-specific household census data. Model C partitioned the statewide estimates by race/ethnicity. Statewide Models A and B estimates of the percentages MSM were strongly correlated (r = 0.74; r-squared = 0.55; p < 0.001) and had similar means (5.82% and 5.88%, respectively) and medians (5.5% and 5.2%, respectively). The estimated percentage MSM in the South was 6.0% (range 3.6-13.2%; median, 5.4%). The combined estimated number of MSM was 2.4 million, including 1,656,500 (69%) whites, 339,400 (14%) blacks, 368,800 (15%) Hispanics, 34,600 (1.4%) Asian/Pacific Islanders, 7,700 (0.3%) American Indians/Alaska Natives, and 11,000 (0.5%) others. The estimates showed considerable variability in state-specific racial/ethnic percentages MSM. MSM population estimates enable better assessment of community vulnerability, HIV/AIDS surveillance, and allocation of resources. Data availability and computational ease of our models suggest other states could similarly estimate their MSM populations.

Detection of acute infections during HIV testing in North Carolina.

BACKGROUND: North Carolina has added nucleic acid amplification testing for the human immunodeficiency virus (HIV) to standard HIV antibody tests to detect persons with acute HIV infection who are viremic but antibody-negative. METHODS: To determine the effect of nucleic acid amplification testing on the yield and accuracy of HIV detection in public health practice, we conducted a 12-month observational study of methods for state-funded HIV testing. We compared the diagnostic performance of standard HIV antibody tests (i.e., enzyme immunoassay and Western blot analysis) with an algorithm whereby serum samples that yielded negative results on standard antibody tests were tested again with the use of nucleic acid amplification. A surveillance algorithm with repeated sensitive-less-sensitive enzyme immunoassay tests was also evaluated. HIV infection was defined as a confirmed positive result on a nucleic acid amplification test or as HIV antibody seroconversion. RESULTS: Between November 1, 2002, and October 31, 2003, 109,250 persons at risk for HIV infection who had consented to HIV testing presented at state-funded sites. There were 606 HIV-positive results. Established infection, as identified by standard enzyme immunoassay or Western blot analysis, appeared in 583 participants; of these, 107 were identified, with the use of sensitive-less-sensitive enzyme immunoassay tests, as recent infections. A total of 23 acutely infected persons were identified only with the use of the nucleic acid amplification algorithm. With all detectable infections taken into account, the sensitivity of standard antibody testing was 0.962 (95 percent confidence interval, 0.944 to 0.976). There were two false positive results on nucleic acid amplification tests. The specificity and positive predictive value of the algorithm that included nucleic acid amplification testing were greater than 0.999 (95 percent confidence interval, 0.999 to >0.999) and 0.997 (95 percent confidence interval, 0.988 to >0.999), respectively. Of the 23 acute HIV infections, 16 were detected at sexually transmitted disease clinics. Emergency measures for HIV prevention protected 48 sex partners and one fetus from high-risk exposure to HIV. CONCLUSIONS: The addition of nucleic acid amplification testing to an HIV testing algorithm significantly increases the identification of cases of infection without impairing the performance of diagnostic testing. The detection of highly contagious, acutely infected persons creates new opportunities for HIV surveillance and prevention.

Evaluation of an HIV prevention intervention adapted for Black men who have sex with men.

OBJECTIVES: We assessed the efficacy of an HIV behavioral intervention adapted for Black men who have sex with men (MSM). METHODS: We conducted serial cross-sectional surveys, 1 baseline measurement followed by initiation of an intervention and 3 follow-up measurements, among Black MSM in 3 North Carolina cities over 1 year. RESULTS: We observed significant decreases in unprotected receptive anal intercourse at 4 months (by 23.8%, n=287) and 8 months (by 24.7%, n=299), and in unprotected insertive anal intercourse (by 35.2%), unprotected receptive anal intercourse (by 44.1%), and any unprotected anal intercourse (by 31.8%) at 12 months (n=268). Additionally, at 12 months, the mean number of partners for unprotected receptive anal intercourse decreased by 40.5%. The mean number of episodes decreased by 53.0% for unprotected insertive anal intercourse, and by 56.8% for unprotected receptive anal intercourse. The percentage of respondents reporting always using condoms for insertive and receptive anal intercourse increased by 23.0% and 30.3%, respectively. CONCLUSIONS: Adapting previously proven interventions designed for other MSM can significantly reduce HIV risk behaviors of Black MSM.

Frequent detection of acute HIV infection in pregnant women.

BACKGROUND: Universal prenatal HIV antibody testing, which does not detect acute HIV, is standard for pregnant women in the United States. Unrecognized HIV acquisition during pregnancy may result in higher rates of perinatal transmission. OBJECTIVE: To determine the prevalence of acute (antibody-negative) HIV infection in pregnant women and to assess the potential for prompt initiation of antiretroviral therapy to prevent perinatal transmission. METHODS: From 1 November 2002 to 30 April 2005, all publicly funded HIV testing sites participated in North Carolina's Screening and Tracing Active Transmission (STAT) Program, which retested all specimens that were HIV antibody negative for HIV RNA using specimen pooling. All patients with acute HIV infection were immediately traced for evaluation, confirmatory testing, counseling, and referral services. For this study, all pregnant women with acute HIV were immediately initiated onto antiretroviral therapy and followed prospectively for pregnancy outcomes. RESULTS: During the study period, 443 women were HIV positive by antibody testing; 15 were HIV antibody negative but positive by RNA assay and of these five were pregnant at the time of testing. The pregnant women received antiretroviral drugs and delivered HIV-uninfected infants. Maternal testing records of all six HIV-infected infants born in North Carolina showed three mothers with chronic HIV infection and three HIV antibody negative at private prenatal testing facilities. CONCLUSIONS: In resource-rich settings, a substantial proportion of residual perinatal transmission may be from HIV acquisition during pregnancy. Standard antibody tests miss acute HIV infection and so algorithms that include pooled HIV RNA testing may improve its detection and represent a further opportunity to prevent perinatal transmission.

Ten Years of Screening and Testing for Acute HIV Infection in North Carolina.

OBJECTIVE: To describe demographic and behavioral characteristics of persons with acute HIV infection (AHI) over time. METHODS: We conducted a retrospective assessment of AHI identified through the Screening and Tracing Active Transmission (STAT) program from 2003 to 2012 in North Carolina (NC). AHI was identified using pooled nucleic acid amplification for antibody negative samples and individual HIV-1 RNA for antibody indeterminate samples. The STAT program provides rapid notification and evaluation. We compared STAT-collected demographic and risk characteristics with all persons requesting tests and all non-AHI diagnoses from the NC State Laboratory of Public Health. RESULTS: The STAT Program identified 236 AHI cases representing 3.4% (95% confidence interval: 3.0% to 3.9%) of all HIV diagnoses. AHI cases were similar to those diagnosed during established HIV. On pretest risk-assessments, AHI cases were predominately black (69.1%), male (80.1%), young (46.8% < 25 years), and men who have sex with men (MSM) (51.7%). Per postdiagnosis interviews, the median age decreased from 35 (interquartile range 25-42) to 27 (interquartile range 22-37) years, and the proportion <25 years increased from 23.8% to 45.2% (trend P = 0.04) between 2003 and 2012. AHI men were more likely to report MSM risk post-diagnosis than on pretest risk-assessments (64%-82.9%; P < 0.0001). Post-diagnosis report of MSM risk in men with AHI increased from 71.4% to 96.2%. CONCLUSIONS: In NC, 3.4% of individuals diagnosed with HIV infection have AHI. AHI screening provides a real-time source of incidence trends, improves the diagnostic yield of HIV testing, and offers an opportunity to limit onward transmission.

Ongoing HIV Transmission and the HIV Care Continuum in North Carolina.

OBJECTIVE: HIV transmission is influenced by status awareness and receipt of care and treatment. We analyzed these attributes of named partners of persons with acute HIV infection (index AHI cases) to characterize the transmission landscape in North Carolina (NC). DESIGN: Secondary analysis of programmatic data. METHODS: We used data from the NC Screening and Tracing of Active Transmission Program (2002-2013) to determine HIV status (uninfected, AHI, or chronic HIV infection [CHI]), diagnosis status (new or previously-diagnosed), and care and treatment status (not in care, in care and not on treatment, in care and on treatment) of index AHI cases' named partners. We developed an algorithm identifying the most likely transmission source among known HIV-infected partners to estimate the proportion of transmissions arising from contact with persons at different HIV continuum stages. We conducted a complementary analysis among a subset of index AHI cases and partners with phylogenetically-linked viruses. RESULTS: Overall, 358 index AHI cases named 932 partners, of which 218 were found to be HIV-infected (162 (74.3%) previously-diagnosed, 11 (5.0%) new AHI, 45 (20.6%) new CHI). Most transmission events appeared attributable to previously-diagnosed partners (77.4%, 95% confidence interval 69.4-85.3%). Among these previously-diagnosed partners, 23.2% (14.0-32.3%) were reported as in care and on treatment near the index AHI case diagnosis date. In the subset study of 33 phylogenetically-linked cases and partners, 60.6% of partners were previously diagnosed (43.9-77.3%). CONCLUSIONS: A substantial proportion of HIV transmission in this setting appears attributable to contact with previously-diagnosed partners, reinforcing the need for improved engagement in care after diagnosis.

Human immunodeficiency virus counseling and testing practices among North Carolina providers.

OBJECTIVE: To estimate the percentage of prenatal care providers who offer human immunodeficiency virus (HIV) testing to pregnant women, investigate how strongly testing is encouraged, and explore testing barriers. METHODS: Between January 2001 and March 2001, we sent surveys to 1381 prenatal care providers in North Carolina, comprised of obstetricians, family physicians who practice obstetrics, and nurse-midwives. A total of 653 questionnaires were returned. RESULTS: Overall, 95.5% of providers who responded reported recommending HIV testing to all pregnant patients. Only 69.2% strongly recommend testing, with obstetricians (73.4%) and family physicians (70.1%) doing so at higher rates than nurse-midwives (55.9%). Almost all respondents (96.9%) strongly recommend testing for women they perceive to be high risk, whereas 39.7% strongly recommend testing to women who have had an HIV test in the past 6 months. When women refuse testing, 48.1% of practitioners inquire about the reason, and 28.2% reoffer the test at a future prenatal appointment. The most significant testing barriers were treating an HIV-positive woman (18.4%) and informing a patient she is HIV positive (14.8%). Respondents report that low literacy and culturally appropriate patient education materials would be most helpful to them. CONCLUSION: Among respondents, most prenatal care providers report that they recommend HIV testing to all pregnant women. However, many respondents base their decision about how strongly to recommend HIV testing on an assessment of the woman's risk for HIV exposure. Significant barriers to offering HIV testing were associated with managing an HIV-positive patient. Providers were most in need of patient education materials.

Integrated screening for tuberculosis and HIV in tuberculosis contact investigations: lessons learned in North Carolina.

Combating the syndemics of tuberculosis (TB) and HIV in the United States will require increasing efficiency as the incidence of TB declines. Fortunately, new tools such as the interferon gamma release assays can be combined with existing strategies such as opt-out HIV testing to facilitate simultaneous, integrated testing for both infections. We describe the lessons learned from our experience with integrated testing for TB and HIV in the setting of TB contact investigations in North Carolina. Integrated testing represents a unique opportunity to leverage TB and HIV program resources to enhance case detection and improve linkages to care. However, joint training in field investigations and diagnostics is critical prior to conducting contact investigations. Furthermore, integrated testing must be tightly coupled to treatment and prevention programs to reduce disease transmission and morbidity from untreated disease in communities.

Investigating a sexual network of black men who have sex with men: implications for transmission and prevention of HIV infection in the United States.

BACKGROUND: HIV infections increased 48% among young Black men who have sex with men (MSM) in the United States between 2006 and 2009. Incomplete understanding of this trend undermines prevention strategy development. We investigated a sexual network to characterize the risk environment in which young Black MSM acquire HIV. METHODS: Persons reported to the state after diagnosis of HIV or syphilis were included, along with sexual partners. We used network mapping alongside descriptive and bivariate statistics to characterize network connections. Generalized linear models assessed predictors of having untraceable sex partners. RESULTS: The network included 398 individuals and 419 sexual relationships. Three-quarters were Black (n = 299); 92% were MSM. Median age at first network appearance was 26 years and decreased over time (P < 0.001). HIV prevalence was at least 29% (n = 117); serostatus was unknown for 47% of the network, either because they were untraceable (n = 150) or refused HIV testing (n = 39). One in 5 network members diagnosed with HIV had a subsequent incident sexually transmitted infection. In multivariable models, one-time encounters increased the risk of having an untraceable partner (risk ratio = 4.51, 95% CI: 2.27 to 8.97), whereas being acutely HIV infected at diagnosis reduced it (risk ratio = 0.27, 95% CI: 0.08 to 0.89). CONCLUSIONS: HIV prevalence in this sexual network of young Black MSM rivals that of sub-Saharan Africa, reflecting dramatically increased risk of acquiring HIV from the moment one entered the network. Prevention efforts for this population must consider the effect of sexual networks on HIV risk and find ways of leveraging network structure to reduce transmission.

Methamphetamine use among newly diagnosed HIV-positive young men in North Carolina, United States, from 2000 to 2005.

BACKGROUND: Methamphetamine (MA) is a new arrival to the Southeastern United States (US). Incidence of HIV is also increasing regionally, but data are limited regarding any association between this trend and MA use. We examined behavioral data from North Carolina (NC) residents newly diagnosed with HIV, collected by the Department of Health between 2000-2005. PRINCIPAL FINDINGS: Among 1,460 newly diagnosed HIV-positive young men, an increasing trend was seen from 2000-2005 in MA use (p = 0.01, total n = 20). In bivariate analyses, users of MA had significantly greater odds of reporting other substance use, including alcohol, powder or crack cocaine, marijuana, and methylenedioxymethamphetamine (MDMA, "ecstasy"). They were also more likely to have reported sexual activity while traveling outside NC; sex with anonymous partners; and previous HIV testing. In a predictive model, MA use had a negative association with nonwhite race, and strong positive associations with powder cocaine, "ecstasy," or intravenous drug use and being a university student. CONCLUSIONS: Similar to trends seen in more urban parts of the US, MA use among newly diagnosed, HIV-positive young men is increasing in NC. These data are among the first to demonstrate this relationship in a region with a burgeoning epidemic of MA use. Opportunities exist for MA-related HIV risk-reduction interventions whenever young men intersect the healthcare system.

Endemic early syphilis among young newly diagnosed HIV-positive men in a southeastern U.S. state.

An epidemic of HIV infections among college students who are primarily men who have sex with men (MSM) have been reported from North Carolina, a state with one of the highest syphilis rates in the southeastern United States. We assessed the proportion of early syphilis coinfections among young HIV-infected individuals statewide and associated risk factors. From January 2002 to July 2006, chart abstractions were performed from North Carolina surveillance records for newly diagnosed HIV-positive men 18-30 years of age reported between 2000-2005, and a subset of women in the same age group. Bivariable and multivariable analyses were conducted to assess early syphilis risk factors among HIV-infected persons. During the 6-year period, there were 1460 HIV-positive men aged 18-30 years reported in North Carolina; 90 (6.2%) were coinfected with early syphilis without a significant change over time. Data were available for 551 HIV-positive women diagnosed from 2002-2005; only 6 (1.1%) were coinfected. Fifty-five percent of coinfected men were diagnosed with both infections on the same date of evaluation. Young HIV-infected men who are black (adjusted odds ratio [aOR] 2.3; 95% confidence interval [CI], 1.3, 4.1), MSM (aOR 3.8; 95% CI, 1.8, 7.8), or reported sex with both genders (aOR 5.1; 95% CI, 2.2, 11.5), or anonymous sex (aOR 2.1; 95% CI, 1.3, 3.3) were more likely to have early syphilis. Although male coinfections have not increased over time, early syphilis has become endemic among young HIV-positive men statewide, emphasizing the need to provide screening for both infections among high-risk individuals.

Nonsupportive peer norms and incarceration as HIV risk correlates for young black men who have sex with men.

Black men who have sex with men (BMSM) are at considerable risk for HIV infection. A convenience sample of BMSM (n=252) attending nightclubs in three North Carolina cities was surveyed to investigate factors associated with unprotected anal intercourse (UAI). About 45% reported UAI in the past 2 months. BMSM who strongly agreed that their male friends used condoms for anal sex were significantly less likely to report any UAI. Recently incarcerated men were significantly more likely to report unprotected insertive anal sex. In secondary analyses, men who reported experiencing discrimination based on their race and nongay identified men reported more favorable peer norms for condom use. Men who reported that their family disapproved of their being gay were more likely to have been incarcerated in the past 2 months. HIV prevention for BMSM must promote supportive peer norms for condom use and address incarceration, racial discrimination, and family disapproval.

Factors and the sociosexual network associated with a syphilis outbreak in rural North Carolina.

OBJECTIVE: An investigation was conducted to determine factors associated with a syphilis outbreak in a rural North Carolina county. STUDY DESIGN: A retrospective chart review was performed on 61 primary (PS), secondary (SS), and early latent (ELS) syphilis case patients reported in Columbus County between January 2001 and February 2002. Sociosexual network analysis was conducted using electronic contact tracing information. RESULTS: We identified 20 PS, 25 SS, and 16 ELS case patients who were predominantly black. Seventy-two percent had reported >or=1 sexual partner with early syphilis, 51% used crack cocaine and/or had sex with a crack-using partner, and 31% exchanged sex for drugs or money. The sexual network exhibited predominantly linear connections between case patients and sexual partners. Adding social connections to the network further demonstrated dense cyclic interactions characteristic of core groups. CONCLUSIONS: The syphilis outbreak in this rural community was associated with crack cocaine and exchange of sex for drugs in a densely interconnected sociosexual network.

Parent opinion of sexuality education in a state with mandated abstinence education: does policy match parental preference?

PURPOSE: Despite public debate about the content of sexuality education in schools, state and federal policy has increasingly financed and legislated abstinence-only education over the past decade. Although public schools strive to meet the needs of parents who, as taxpayers, fund the educational system, little is known about parental desires regarding sexuality education in states with mandated abstinence education. The objective of this study was to assess parental opinion about sexuality education in public schools in North Carolina, a state with mandated abstinence education. METHODS: Computer-assisted, anonymous, cross-sectional telephone surveys were conducted among 1306 parents of North Carolina public school students in grades K-12. Parental support for sexuality education in public schools and 20 sexuality education topics was measured. We defined comprehensive sexuality education as education that includes a discussion of how to use and talk about contraception with partners. RESULTS: Parents in North Carolina overwhelmingly support sexuality education in public schools (91%). Of these respondents, the majority (89%) support comprehensive sexuality education. Less than a quarter of parents oppose teaching any specific topic, including those typically viewed as more controversial, such as discussions about sexual orientation, oral sex, and anal sex. Parents' level of education was inversely related to support for specific sexuality education topics and comprehensive education, although these differences were small in magnitude. More than 90% of respondents felt that parents and public health professionals should determine sexuality education content and opposed the involvement of politicians. CONCLUSIONS: Current state-mandated abstinence sexuality education does not match parental preference for comprehensive sexuality education in North Carolina public schools.
