RESUMEN
National trends in gonorrhea rates may obscure informative local variations in morbidity. We used group-based trajectory models to identify groups of counties with similar gonorrhea rate trajectories among non-Hispanic White (NHW) and non-Hispanic Black (NHB) females using county-level data on gonorrhea cases in US females from 2003 to 2018. We assessed models with 1-15 groups and selected final models based on fit statistics and identification of divergent trajectory groups with distinct intercepts and/or slopes. We mapped counties by assigned trajectory group and examined the association of county characteristics with group membership. We identified 7 distinct gonorrhea trajectory groups for NHW females and 9 distinct trajectory groups for NHB females. All identified groups for NHW female morbidity experienced increasing gonorrhea rates with a limited range (11.6-183.3/100,000 NHW females in 2018); trajectories of NHB female morbidity varied widely in rates (146.6-966.0/1000 NHB females in 2018) and included 3 groups of counties that experienced a net decline in gonorrhea rates. Counties with higher NHW female morbidity had lower adult sex ratios, lower health insurance coverage, and lower marital rates among NHW adults. Counties with higher NHB female morbidity were more urban, experienced higher rates of poverty, and had lower rates of marriage among NHB adults. Morbidity patterns did not always follow geographic proximity, which could be explained by variation in social determinants of health. Our results demonstrated a highly heterogenous gonorrhea epidemic among NHW and NHB US females, which should prompt further analysis into the differential drivers of gonorrhea morbidity.

In December 2019, a cluster of cases of pneumonia emerged in Wuhan City in central China's Hubei Province. Genetic sequencing of isolates obtained from patients with pneumonia identified a novel coronavirus (2019-nCoV) as the etiology (1). As of February 4, 2020, approximately 20,000 confirmed cases had been identified in China and an additional 159 confirmed cases in 23 other countries, including 11 in the United States (2,3). On January 17, CDC and the U.S. Department of Homeland Security's Customs and Border Protection began health screenings at U.S. airports to identify ill travelers returning from Wuhan City (4). CDC activated its Emergency Operations Center on January 21 and formalized a process for inquiries regarding persons suspected of having 2019-nCoV infection (2). As of January 31, 2020, CDC had responded to clinical inquiries from public health officials and health care providers to assist in evaluating approximately 650 persons thought to be at risk for 2019-nCoV infection. Guided by CDC criteria for the evaluation of persons under investigation (PUIs) (5), 210 symptomatic persons were tested for 2019-nCoV; among these persons, 148 (70%) had travel-related risk only, 42 (20%) had close contact with an ill laboratory-confirmed 2019-nCoV patient or PUI, and 18 (9%) had both travel- and contact-related risks. Eleven of these persons had laboratory-confirmed 2019-nCoV infection. Recognizing persons at risk for 2019-nCoV is critical to identifying cases and preventing further transmission. Health care providers should remain vigilant and adhere to recommended infection prevention and control practices when evaluating patients for possible 2019-nCoV infection (6). Providers should consult with their local and state health departments when assessing not only ill travelers from 2019-nCoV-affected countries but also ill persons who have been in close contact with patients with laboratory-confirmed 2019-nCoV infection in the United States.

Spatial analyses of gonorrhea morbidity among women often highlight the Southeastern United States but may not provide information on geographic variation in the magnitude of racial disparities; such maps also focus on geographic space, obscuring underlying population characteristics. We created a series of visualizations depicting both county-level racial disparities in female gonorrhea diagnoses and variations in population size. We calculated county- and region-level race-specific relative rates (RelR) and between-race rate differences (RDs) and rate ratios (RRs) comparing gonorrhea case rates in non-Hispanic Black (NHB) versus non-Hispanic White (NHW) women. We then created proportional symbol maps with color representing counties' RelR/RD/RR category and symbol size representing counties' female population. Gonorrhea rates among NHB women were highest in the Midwest (718.7/100,000) and West (504.8), rates among NHW women were highest in the West (74.1) and Southeast (72.1). The RDs were highest in the Midwest (654.6 excess cases/100,000) and West (430.7), whereas the RRs were highest in the Northeast (12.4) and Midwest (11.2). Nearly all US counties had NHB female rates ≥3× those in NHW women, with NHB women in most highly populated counties experiencing ≥9-fold difference in gonorrhea rates. Racial disparities in gonorrhea were not confined to the Southeast; both relative and absolute disparities were equivalent or larger in magnitude in areas of the Northeast, Midwest, and West. Our findings help counter damaging regional stereotypes, provide evidence to refocus prevention efforts to areas of highest disparities, and suggest a useful template for monitoring racial disparities as an actionable public health metric.

Gonorrhea, the sexually transmitted disease (STD) caused by Neisseria gonorrhoeae, is the second most common notifiable disease in the United States after chlamydia; 468,514 cases were reported to state and local health departments in 2016, an increase of 18.5% from 2015 (1). N. gonorrhoeae has progressively developed resistance to most antimicrobials used to treat the infection (2). As a result, CDC recommends two antimicrobials (250 mg of ceftriaxone [IM] plus 1 g of azithromycin [PO]) for treating uncomplicated gonorrhea to improve treatment efficacy and, potentially, to slow the emergence and spread of antimicrobial resistance. To monitor adherence to the current CDC-recommended regimen for uncomplicated gonorrhea, CDC reviewed enhanced data collected on a random sample of reported cases of gonorrhea in seven jurisdictions participating in the STD Surveillance Network (SSuN) and estimated the proportion of patients who received the CDC-recommended regimen for uncomplicated gonorrhea, by patient characteristics and diagnosing facility type. In 2016, the majority of reported patients with gonorrhea (81%) received the recommended regimen. There were no differences in the proportion of patients receiving the recommended regimen by age or race/ethnicity; however, patients diagnosed with gonorrhea in STD (91%) or family planning/reproductive health (94%) clinics were more likely to receive this regimen than were patients diagnosed in other provider settings (80%). These data document high provider adherence to CDC gonorrhea treatment recommendations in specialty STD clinics, indicating high quality of care provided in those settings. Local and state health departments should monitor adherence with recommendations in their jurisdictions and consider implementing interventions to improve provider and patient compliance with gonorrhea treatment recommendations where indicated.

BACKGROUND: Inequalities in Neisseria gonorrhoeae (gonorrhea) burden by sexual minority status in the United States are difficult to quantify. Sex of sex partner is not routinely collected for reported cases. Population estimates of men who have sex with men (MSM) necessary to calculate case rates have not been available until recently. For these reasons, trends in reported gonorrhea rates among MSM have not been described across multiple jurisdictions. METHODS: We estimated of the number of MSM cases reported in 6 jurisdictions continuously participating in the STD Surveillance Network 2010-2015 based on interviews with a random sample of cases. Data were obtained for Baltimore, Philadelphia, New York City, San Francisco, California (excluding San Francisco), and Washington State. Estimates of the MSM, heterosexual male (MSW) and female populations were obtained from recently published estimates and census data. Case rates and rate-ratios were calculated comparing trends in reported cases among MSM, heterosexual males and women. RESULTS: The proportion of male gonorrhea cases among MSM varied by jurisdiction (range: 20% to 98%). Estimated MSM rate increased from 1369 cases per 100,000 in 2010 to 3435 cases per 100,000 in 2015. Between 2010 and 2015, the MSM-to-Women gonorrhea rate ratio increased from 13:1 to 24:1, and the MSM-to-MSW gonorrhea rate ratio increased from 16:1 to 31:1. CONCLUSIONS: Estimated gonorrhea rate among MSM increased in a network of 6 geographically diverse US jurisdictions. Estimating the size of this population, determining MSM among reported cases and estimating rates are essential first steps for better understanding the changing epidemiology of gonorrhea.

BACKGROUND: We examined the infrastructure for US public sexually transmitted disease (STD) clinical services. METHODS: In 2013 to 2014, we surveyed 331 of 1225 local health departments (LHDs) who either reported providing STD testing/treatment in the 2010 National Profile of Local Health Departments survey or were the 50 local areas with the highest STD cases or rates. The sample was stratified by jurisdiction population size. We examined the primary referral clinics for STDs, the services offered and the impact of budget cuts (limited to government funding only). Data were analyzed using SAS, and analyses were weighted for nonresponse. RESULTS: Twenty-two percent of LHDs cited a specialty STD clinic as their primary referral for STD services; this increased to 53.5% of LHDs when combination STD-family planning clinics were included. The majority of LHDs (62.8%) referred to clinics providing same-day services. Sexually transmitted disease clinics more frequently offered extragenital testing for chlamydia and/or gonorrhea (74.7%) and gonorrhea culture (68.5%) than other clinics (52.9%, 46.2%, respectively; P < 0.05). The majority of LHDs (61.5%) reported recent budget cuts. Of those with decreased budgets, the most common impacts were fewer clinic hours (42.8%; 95% confidence interval [CI], 24.4-61.2), reduced routine screening (40.2%; 95% CI, 21.7-58.8) and reductions in partner services (42.1%; 95% CI, 23.6-60.7). One quarter of those with reduced STD budgets increased fees or copays for clients. CONCLUSIONS: Findings demonstrate gaps and reductions in US public STD services including clinical services that play an important role in reducing disease transmission. Furthermore, STD clinics tended to offer more specialized STD services than other public clinics.

BACKGROUND: Expedited partner therapy (EPT) has been shown to prevent reinfection in persons with gonorrhea and to plausibly reduce incidence. The Centers for Disease Control and Prevention recommends EPT as an option for treating sex partners of heterosexual patients. Few studies that examine how the reported use of this valuable intervention differs by patient and provider characteristics and by geography across multiple jurisdictions in the United States are currently available. METHODS: Case and patient interview data were obtained for a random sample of reported cases from 7 geographically disparate US jurisdictions participating in the Sexually Transmitted Disease (STD) Surveillance Network. These data were weighted to be representative of all reported gonorrhea cases in the 7 study sites. Patient receipt of EPT was estimated, and multivariate models were constructed separately to examine factors associated with receipt of EPT for heterosexuals and for men who have sex with men. RESULTS: Overall, 5.4% of patients diagnosed and reported as having gonorrhea reported receiving EPT to treat their sex partners. Heterosexual patients were more likely to have received EPT than men who have sex with men at 6.6% and 2.6% of patients, respectively. Receipt of EPT did not vary significantly by race, Hispanic ethnicity, or age for either group, although significant variation was observed in different provider settings, with patients from family planning/reproductive health and STD clinic settings more likely to report receiving EPT. Jurisdiction variations were also observed with heterosexual patients in Washington State most likely (35.5%), and those in New York City, Connecticut, and Philadelphia least likely to report receiving EPT (<2%). CONCLUSIONS: With the exception of one jurisdiction in the STD Surveillance Network actively promoting EPT use, patient-reported receipt of the intervention remains suboptimal across the network. Additional efforts to promote EPT, especially for patients diagnosed in private provider and hospital settings, are needed to realize the full potential of this valuable gonorrhea control intervention.

BACKGROUND: Replacing oral treatments with ceftriaxone is a central component of public health efforts to slow the emergence of cephalosporin-resistant Neisseria gonorrhoeae in the United States; US gonorrhea treatment guidelines were revised accordingly in 2010. However, current US gonorrhea treatment practices have not been well characterized. METHODS: Six city and state health departments in Cycle II of the STD Surveillance Network (SSuN) contributed data on all gonorrhea cases reported in 101 counties and independent cities. Treatment data were obtained through local public health surveillance and interviews with a random sample of patients. Cases were weighted to adjust for site-specific sample fractions and for differential nonresponse by age, sex, and provider type. RESULTS: From 2010 to 2012, 135,984 gonorrhea cases were reported in participating areas, 15,246 (11.2%) of which were randomly sampled. Of these, 7,851 (51.5%) patients were interviewed. Among patients with complete treatment data, 76.8% received ceftriaxone, 16.4% received an oral cephalosporin, and 6.9% did not receive a cephalosporin; 51.9% of persons were treated with a regimen containing ceftriaxone and either doxycycline or azithromycin. Ceftriaxone treatment increased significantly by year (64.1% of patients in 2010, 79.3% in 2011, 85.4% in 2012; P = 0.0001). Ceftriaxone use varied widely by STD Surveillance Network site (from 44.6% to 95.1% in 2012). CONCLUSIONS: Most persons diagnosed as having gonorrhea between 2010 and 2012 in the United States received ceftriaxone, and its use has increased since the release of the 2010 Centers for Disease Control and Prevention STD Treatment Guidelines.

BACKGROUND: The association between area-based social factors and sexually transmitted diseases has been demonstrated in numerous studies. Such associations have not previously been explored for their potential to quantify likelihood of higher transmission of gonorrhea in small geographic areas. METHODS: Aggregate census tract-level sociodemographic factors in 4 domains (demographics, educational attainment, household income, and housing characteristics) were merged with female gonorrhea incidence data from 113 counties in 10 US states. Multivariate models were constructed, and a tract-level composite gonorrhea risk index was calculated. This composite risk index was validated against gonorrhea incidence among women from 2 independent states. RESULTS: Seven tract-level factors were found to be most strongly correlated with female gonorrhea incidence: educational attainment, proportion of female headed households, annual household income below US $20,000, proportion of population non-Hispanic black, proportion of housing units currently vacant, proportion of population reporting moving in last year, and proportion of households that are nonfamily units. Composite index was highly correlated with female gonorrhea in the study area and validated with independent data. CONCLUSIONS: Social factors predict gonorrhea incidence at the census tract level and identify small areas at risk for higher morbidity. These data may be used by health departments and health care practices to develop geographically based disease prevention and control efforts. This is especially useful because gonorrhea incidence data are not routinely available below the county level in many states.

BACKGROUND: Expedited partner therapy (EPT) is a potential partner treatment strategy. Significant efforts have been devoted to policies intended to facilitate its practice. However, few studies have attempted to evaluate these policies. METHODS: We used data on interviewed gonorrhea cases from 12 sites in the STD Surveillance Network in 2010 (n = 3404). Patients reported whether they had received EPT. We coded state laws relevant to EPT for gonorrhea using Westlaw legal research database and the general legal status of EPT in STD Surveillance Network sites from Centers for Disease Control and Prevention's Web site in 2010. We also coded policy statements by medical and other boards. We used χ tests to compare receipt of EPT by legal/policy variables, patient characteristics, and provider type. Variables significant at P < 0.10 in bivariate analyses were included in a logistic regression model. RESULTS: Overall, 9.5% of 2564 interviewed patients with gonorrhea reported receiving EPT for their partners. Receipt of EPT was significantly higher where laws and policies authorizing EPT existed. Where EPT laws for gonorrhea existed and EPT was permissible, 13.3% of patients reported receiving EPT as compared with 5.4% where there were no EPT laws and EPT was permissible, and 1.0% where there were no EPT laws and EPT was potentially allowable (P < 0.01). Expedited partner therapy was higher where professional boards had policy statements supporting EPT (P < 0.01). Receipt of EPT did not differ by most patient characteristics or provider type. Policy-related findings were similar in adjusted analyses. CONCLUSIONS: Expedited partner therapy laws and policies were associated with higher reports of receipt of EPT among interviewed gonorrhea cases.

OBJECTIVES: We assessed population-level trends in human immunodeficiency virus (HIV) and Neisseria gonorrhoeae co-infection among adult males in Washington State between 1996 and 2007. METHODS: Population-based categorical disease surveillance registries for gonorrhea and for HIV were electronically matched and merged at the record level and incidence rates were calculated for reported HIV-positive and presumed HIV-negative men. RESULTS: The incidence of gonorrhea infection increased significantly among both HIV-positive and presumed HIV-negative men from 1996 to 2005, and this trend has recently reversed for both groups. The annual incidence rate of gonorrhea among HIV-positive men was found to be higher in all years than among men presumed to be HIV-negative. CONCLUSIONS: Inequality in the burden of gonorrhea by HIV-infection status suggests continuing sexual risk-taking among HIV-positive men as well as possible barriers to diagnosis, treatment, and partner services. This inequality may also reflect significant differences in gonorrhea burden among men who have sex with men as well as by HIV status. Monitoring emergent secular trends in population-level HIV/sexually transmitted infection comorbidity through registry matching is an achievable strategy for developing an evidence base to inform program collaboration and service integration efforts aimed at providing more comprehensive disease prevention services.
RESUMEN
Data to guide programmatic decisions in public health are needed, but frequently epidemiologists are limited to routine case report data for notifiable conditions such as sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). However, case report data are frequently incomplete or provide limited information on comorbidity or risk factors. Supplemental data often exist but are not easily accessible, due to a variety of real and perceived obstacles. Data matching, defined as the linkage of records across two or more data sources, can be a useful method to obtain better or additional data, using existing resources. This article reviews the practical considerations for matching STD and HIV surveillance data with other data sources, including examples of how STD and HIV programs have used data matching.
RESUMEN
In 2005, the Centers for Disease Control and Prevention established the STD Surveillance Network (SSuN), a sentinel surveillance system comprising local, enhanced sexually transmitted disease (STD) surveillance systems that follow common protocols. The purpose of SSuN is to improve the capacity of national, state, and local STD programs to detect, monitor, and respond rapidly to trends in STDs through enhanced collection, reporting, analysis, visualization, and interpretation of clinical, behavioral, and geographic information obtained from a geographically diverse sample of individuals diagnosed with STDs. To demonstrate the utility of a national sentinel surveillance network, this article reviews the lessons learned from the first three years of SSuN, which, through its enhanced gonorrhea and genital warts sentinel surveillance projects, has proved to be a useful adjunct to routine STD surveillance in the U.S. that can be expanded into other areas of STD public health interest.
