There is an unmet need for developing drugs for the treatment of gonorrhea, due to rapidly evolving resistance of Neisseria gonorrhoeae against antimicrobial drugs used for empiric therapy, an increase in globally reported multidrug resistant cases, and the limited available therapeutic options. Furthermore, few drugs are under development. Development of antimicrobials is hampered by challenges in clinical trial design, limitations of available diagnostics, changes in and varying standards of care, lack of robust animal models, and clinically relevant pharmacodynamic targets. On April 23, 2021, the U.S. Food and Drug Administration; Centers for Disease Control and Prevention; and National Institute of Allergy and Infectious Diseases, National Institutes of Health co-sponsored a workshop with stakeholders from academia, industry, and regulatory agencies to discuss the challenges and strategies, including potential collaborations and incentives, to facilitate the development of drugs for the treatment of gonorrhea. This article provides a summary of the workshop.

No vaccines and few chemoprophylaxis options exist for the prevention of bacterial sexually transmitted infections (STIs) (specifically syphilis, chlamydia, and gonorrhea). These infections have increased in the United States and disproportionately affect gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW). In three large randomized controlled trials, 200 mg of doxycycline taken within 72 hours after sex has been shown to reduce syphilis and chlamydia infections by >70% and gonococcal infections by approximately 50%. This report outlines CDC's recommendation for the use of doxycycline postexposure prophylaxis (doxy PEP), a novel, ongoing, patient-managed biomedical STI prevention strategy for a selected population. CDC recommends that MSM and TGW who have had a bacterial STI (specifically syphilis, chlamydia, or gonorrhea) diagnosed in the past 12 months should receive counseling that doxy PEP can be used as postexposure prophylaxis to prevent these infections. Following shared decision-making with their provider, CDC recommends that providers offer persons in this group a prescription for doxy PEP to be self-administered within 72 hours after having oral, vaginal, or anal sex. The recommended dose of doxy PEP is 200 mg and should not exceed a maximum dose of 200 mg every 24 hours.Doxy PEP, when offered, should be implemented in the context of a comprehensive sexual health approach, including risk reduction counseling, STI screening and treatment, recommended vaccination and linkage to HIV PrEP, HIV care, or other services as appropriate. Persons who are prescribed doxy PEP should undergo bacterial STI testing at anatomic sites of exposure at baseline and every 3-6 months thereafter. Ongoing need for doxy PEP should be assessed every 3-6 months as well. HIV screening should be performed for HIV-negative MSM and TGW according to current recommendations.

Congenital syphilis, first described by Gaspar Torella in 1497, results primarily from the transplacental passage of Treponema pallidum and continues to cause major negative consequences worldwide.1 After a steady decline in U.S. cases of primary and secondary syphilis after 1990, which led to hopes of its elimination, rates hit a nadir in 2001. Unfortunately, the rates have subsequently increased among men and women of reproductive age, as well as infants, and in 2021, the rate of congenital syphilis in the United States was the highest it has been in nearly 30 years.2

COVID-19 has brought unprecedented challenges to clinical and public health laboratories. While U.S. laboratories have continued striving to provide quality test results during the pandemic, the uncertainty and lack of supplies became a significant hurdle, hindering day-to-day laboratory operations and the ability to increase testing capacity for both SARS-CoV-2 and non-COVID-19 testing. In addition, long-standing laboratory workforce shortages became apparent, hindering the ability of clinical and public health laboratories to rapidly increase testing. The American Society for Microbiology, the College of American Pathologists, the National Coalition of STD Directors, and the Emerging Infections Network independently conducted surveys in 2020 and early 2021 to assess the capacity of the nation's clinical laboratories to respond to the increase in demand for testing during the COVID-19 pandemic. The results of these surveys highlighted the shortages of crucial supplies for SARS-CoV-2 testing and supplies for other routine laboratory diagnostics, as well as a shortage of trained personnel to perform testing. The conclusions are based on communications, observations, and the survey results of the clinical laboratory, public health, and professional organizations represented here. While the results of each survey considered separately may not be representative of the entire community, when considered together they provide remarkably similar results, further validating the findings and highlighting the importance of laboratory supply chains and the personnel capable of performing these tests for any response to a large-scale public health emergency.

INTRODUCTION: Rates of congenital syphilis cases are increasing, particularly among lower socioeconomic populations within the southern United States. Medicaid covers a significant portion of these births, which provides an opportunity to improve birth outcomes. This project sought to collect information from key stakeholders to assess facilitators of and barriers to Medicaid funding of prenatal syphilis screening and to provide insight into improving screening and lowering incidence through the Medicaid program. METHODS: Seven southern states (Alabama, Georgia, Kentucky, Louisiana, North Carolina, South Carolina, and Tennessee) were identified for this assessment. Researchers conducted a legal and policy analysis for each state to gather information on factors affecting congenital syphilis prevention, identifying knowledge gaps, and inform the development of interview guides. Seventeen structured interviews with 29 participants were conducted to gather information on facilitators and barriers to receiving timely prenatal syphilis screening through the Medicaid program. Interview transcripts were analyzed and compared to identify key themes. RESULTS: Barriers to timely prenatal syphilis screening include varied laws among the states on the timing of screening, Medicaid reimbursement policies that may not adequately incentivize testing, Medicaid enrollment issues that affect both enrollment and continuity of care, and lack of clear understanding among providers on recommended testing. CONCLUSION: This work provides insight into systemic issues that may be affecting rates of prenatal syphilis screening and incidence among Medicaid enrollees and others in the U.S. South. To address rising congenital syphilis cases, policymakers should consider requiring third trimester syphilis screening, adopting policies to enhance access to prenatal care, adapting Medicaid payment and incentive models, and promoting collaboration between Medicaid and public health agencies.

In a Policy Forum piece, Dr. Nicola Low and colleagues define the research agenda for Mpox virus and transmission through sexual contact.

Assisted partner services (APS) is a longstanding public health strategy to reduce transmission of STI and HIV in the U.S. However, with rapidly increasing rates of STI, innovations to APS are needed to allow health departments to conserve limited public health resources while improving the effectiveness of APS. Disease Intervention Specialists (DIS), public health staff who conduct APS, have a wealth of experience in identifying, locating, and interviewing index patients and their sexual partners, but are currently limited in the services that they are able to provide in the field. While several state and local health departments are working to expand the role of DIS to incorporate less traditional APS activities, such programs are uncommon. We discuss several services that DIS could conceivably provide in the field, such as STI testing, treatment, and vaccination, and identify critical issues to be addressed in order to implement these changes in DIS activities on a larger scale. Broadening the scope of DIS activities may result in multiple benefits to health departments, including more effectively delivering STI testing and treatment to hard to reach populations, imparting more responsibility to DIS, thereby potentially increasing job satisfaction, and building a workforce that is better prepared for public health crises. Effective approaches to address variable state level regulations governing DIS scope of practice are needed.

High prevalences of HIV and other sexually transmitted infections (STIs) have been reported in the current global monkeypox outbreak, which has affected primarily gay, bisexual, and other men who have sex with men (MSM) (1-5). In previous monkeypox outbreaks in Nigeria, concurrent HIV infection was associated with poor monkeypox clinical outcomes (6,7). Monkeypox, HIV, and STI surveillance data from eight U.S. jurisdictions* were matched and analyzed to examine HIV and STI diagnoses among persons with monkeypox and assess differences in monkeypox clinical features according to HIV infection status. Among 1,969 persons with monkeypox during May 17-July 22, 2022, HIV prevalence was 38%, and 41% had received a diagnosis of one or more other reportable STIs in the preceding year. Among persons with monkeypox and diagnosed HIV infection, 94% had received HIV care in the preceding year, and 82% had an HIV viral load of <200 copies/mL, indicating HIV viral suppression. Compared with persons without HIV infection, a higher proportion of persons with HIV infection were hospitalized (8% versus 3%). Persons with HIV infection or STIs are disproportionately represented among persons with monkeypox. It is important that public health officials leverage systems for delivering HIV and STI care and prevention to reduce monkeypox incidence in this population. Consideration should be given to prioritizing persons with HIV infection and STIs for vaccination against monkeypox. HIV and STI screening and other recommended preventive care should be routinely offered to persons evaluated for monkeypox, with linkage to HIV care or HIV preexposure prophylaxis (PrEP) as appropriate.

Sexually transmitted infections (STIs) constitute an epidemic of tremendous magnitude, with an estimated 27 million persons acquiring a new STI in 2018 at a cost of $16 billion [1, 2]. Reported disease rates underestimate the true burden of infection because the majority of STIs are asymptomatic and underreported [3]. STIs have far-reaching public health consequences on the sexual and reproductive health of individuals, as well as long-term healthcare costs to the community [2]. Due to the dramatic increase in reportable STI rates with resultant reproductive health consequences, an STI National Strategic Plan (https://www.hhs.gov/sites/default/files/STI-National-Strategic-Plan-2021-2025.pdf) was developed with actionable goals, objectives, and strategies for prevention that focus on 4 of the STIs with the highest morbidity rates (chlamydia, gonorrhea, syphilis, and human papillomavirus), though most of the components of the plan are applicable to other STIs (herpes simplex virus, trichomoniasis, Mycoplasma genitalium).

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Congenital syphilis (CS) is on the rise in the United States and is a growing public health concern. CS is an infection with Treponema pallidum in an infant or fetus, acquired via transplacental transmission when a pregnant woman has untreated or inadequately treated syphilis. Pregnant women with untreated syphilis are more likely to experience pregnancies complicated by stillbirth, prematurity, low birth weight, and early infant death, while their children can develop clinical manifestations of CS such as hepatosplenomegaly, bone abnormalities, developmental delays, and hearing loss. One of the ways CS can be prevented is by identifying and treating infected women during pregnancy with a benzathine penicillin G regimen that is both appropriate for the maternal stage of syphilis and initiated at least 30 days prior to delivery. In this article we discuss many of the challenges faced by both public health and healthcare systems with regards to this preventable infection, summarize missed opportunities for CS prevention, and provide practical solutions for future CS prevention strategies.

During the 2017-2018 National Health and Nutrition Examination Survey, urine samples from participants aged 14-59 years were tested for Mycoplasma genitalium infection. Overall prevalence was 1.7% (95% CI: 1.1%, 2.7%). Prevalence was similar between males (1.8%, 95% CI: 0.9%, 3.1%) and females (1.7%, 95% CI: 0.8%, 3.0%).

Sexually transmitted infections (STIs) caused by the bacteria Neisseria gonorrhoeae (gonococcal infections) have increased 63% since 2014 and are a cause of sequelae including pelvic inflammatory disease, ectopic pregnancy, and infertility and can facilitate transmission of human immunodeficiency virus (HIV) (1,2). Effective treatment can prevent complications and transmission, but N. gonorrhoeae's ability to acquire antimicrobial resistance influences treatment recommendations and complicates control (3). In 2010, CDC recommended a single 250 mg intramuscular (IM) dose of ceftriaxone and a single 1 g oral dose of azithromycin for treatment of uncomplicated gonococcal infections of the cervix, urethra, and rectum as a strategy for preventing ceftriaxone resistance and treating possible coinfection with Chlamydia trachomatis (4). Increasing concern for antimicrobial stewardship and the potential impact of dual therapy on commensal organisms and concurrent pathogens (3), in conjunction with the continued low incidence of ceftriaxone resistance and the increased incidence of azithromycin resistance, has led to reevaluation of this recommendation. This report, which updates previous guidelines (5), recommends a single 500 mg IM dose of ceftriaxone for treatment of uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. If chlamydial infection has not been excluded, concurrent treatment with doxycycline (100 mg orally twice a day for 7 days) is recommended. Continuing to monitor for emergence of ceftriaxone resistance through surveillance and health care providers' reporting of treatment failures is essential to ensuring continued efficacy of recommended regimens.

BACKGROUND: Antimicrobial resistance in Mycoplasma genitalium (MG), a cause of urethritis, is a growing concern. Yet little is known about the geographic distribution of MG resistance in the U.S. or associated clinical outcomes. We evaluated the frequency of MG among men with urethritis, resistance mutations, and post-treatment symptom persistence. METHODS: We enrolled men presenting with urethritis symptoms to 6 U.S. sexually transmitted disease (STD) clinics during June 2017-July 2018; men with urethritis were eligible for follow-up contact and (if persistent symptoms or MG) chart review. Urethral specimens were tested for MG and other bacterial STDs. Mutations in 23S rRNA loci (macrolide-associated mutations [MRMs]) and parC and gyrA (quinolone-associated mutations [QRMs]) were detected by targeted amplification/Sanger sequencing. RESULTS: Among 914 evaluable participants, 28.7% (95% CI 23.8-33.6) had MG. Men with MG were more often black (79.8% vs 66%), <30 years (72.9% vs 56.1%), and reported only female partners (83.7% vs 74.2%) than men without MG. Among MG-positive participants, 64.4% (95% CI 58.2%-70.3%) had MRM, 11.5% (95% CI 7.9-16.0%) had parC mutations, and 0% had gyrA mutations. Among participants treated with azithromycin-based therapy at enrollment and who completed the follow-up survey, persistent symptoms were reported by 25.8% of MG-positive/MRM-positive men, 13% of MG-positive/MRM-negative men, and 17.2% of MG-negative men. CONCLUSIONS: MG infection was common among men with urethritis; MRM prevalence was high among men with MG. Persistent symptoms following treatment were frequent among men with and without MG.

We estimated the availability of the injectable antimicrobial drugs recommended for point-of-care treatment of gonorrhea and syphilis among US physicians who evaluated patients with sexually transmitted infections in 2016. Most physicians did not have these drugs available on-site. Further research is needed to determine the reasons for the unavailability of these drugs.

Sexually transmitted infection (STI) rates have been rising in the era of biomedical human immune deficiency virus (HIV) prevention.1 Concerns regarding antibiotic resistance are increasing.2 The traditional response to such trends has been biomedical, emphasizing a series of individual encounters: first, between the pathogen and a susceptible person, and then between that infected person and the health care system. Efforts to concurrently incorporate behavioral epidemiology and behavioral surveillance have generally included measurement of numbers (and types of) partners, timing of partnerships, patterns of mixing among subpopulations, and sex of sex partners. Sexual practices, such as oral, anal, and vaginal sex, have not been consistently measured with sufficient granularity in national behavioral surveys and some research studies. Moreover, studies of sexual repertoires—the sequence of sexual practices/positions in specific sexual encounters—such as Foxman et al, 19983 have been rare. Predictably, the reaction to the current situation emphasizes an increased focus on (traditional) STI treatment optimization (better antibiotics, different regimens, enhanced systems for screening and treatment).

Trichomonas vaginalis (TV) infection is the most prevalent curable sexually transmitted infection in the United States and worldwide. Most TV infections are asymptomatic, and the accurate diagnosis of this infection has been limited by lack of sufficiently sensitive and specific diagnostic tests, particularly for men. To provide updates for the 2010 Centers for Disease Control and Prevention's Sexually Transmitted Diseases Treatment Guidelines, a PubMed search was conducted of all TV literature published from 9 January 2004 through 24 September 2008. Approximately 175 pertinent abstracts and articles were reviewed and discussed with national experts. This article describes advances in TV diagnostics which have led to an improved understanding of the epidemiology of this pathogen, as well as potential biologic and epidemiological interactions between TV and human immunodeficiency virus (HIV). New data on treatment outcomes, metronidazole-resistant TV, management of nitroimidazole-allergic patients, frequency of recurrent TV infection following treatment, and screening considerations for TV in certain populations are also presented.

BACKGROUND: Little is known about access to medicine among immigrant Latinos in the United States (US). This study explored access to, and use of, prescription drugs obtained from nonmedical sources among recently arrived, Spanish-speaking immigrant Latinos in rural North Carolina (NC). METHODS: Our community-based participatory research partnership collected, analyzed, and interpreted data from individual in-depth interviews with Latino community members and rural health service providers. A purposive sample of 30 community members, including traditional healers, religious leaders, transgender Latinos, heterosexual Latino men and women, and Latino gay men, were interviewed to gain emic ("insider") perspectives on use of nonmedical sources of prescription drugs. Six local Latino health service providers also were interviewed to gain etic ("outsider") perspectives on use. RESULTS: Participants described the roles of tiendas (grocers), family, and social networks in accessing treatment advice and prescription drugs. They described health care expectations among immigrants and contingencies for accessing prescription drugs in the US. Prescription medicines (eg, antibiotics, hormones, Viagra, analgesics), injection equipment (eg, syringes), and medical advice were identified as readily available from nonmedical sources. CONCLUSIONS: Increased access to formalized health care and effective health education initiatives are needed to meet the challenges facing immigrant Latinos.

Optimal methods for the diagnosis of rectal gonococcal and chlamydial infection are uncertain. This study evaluated performance of culture and nucleic acid amplification tests (NAATs) for rectal chlamydial and gonococcal diagnosis. From July 2003 until February 2007, 441 rectal test sets were collected from individuals attending a sexually transmitted disease clinic and 3 HIV clinics who gave a history of anal intercourse or were women at high risk for N. gonorrhoeae or C. trachomatis infections. Rectal swab specimens were tested using culture and commercial NAATs employing Transcription Mediated Amplification (TMA), Strand Displacement Amplification (SDA), and Polymerase Chain Reaction (PCR) Amplification. Test performance was evaluated using a rotating standard by which patients were classified infected if either two or three comparator tests were positive. Test sensitivities for the detection of N. gonorrhoeae ranged from 66.7% to 71.9% for culture to 100% for TMA. Specificities were 99.7% to 100% for culture and greater than 95.5% for all 3 NAATs. Test sensitivities for C. trachomatis ranged from 36.1% to 45.7% for culture and among NAATS from 91.4% to 95.8% for PCR to 100% for TMA. Specificities of the NAATs ranged from 95.6% to 98.5% (2 of 3 standard) and from 88.8% to 91.8% (3 of 3 standard). Over 60% and 80% of gonococcal and chlamydial infections among men who have sex with men and over 20% of chlamydial infections in women, respectively, would have been missed if the rectal site had not been tested. Currently available NAATs are more sensitive than culture for detection of chlamydial and gonococcal infection at the rectal site.
