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. Introduction These STI treatment guidelines complement Recommendations for Providing Quality Sexually Transmitted Diseases Clinical The term “sexually transmitted infection” (STI) refers to Services, 2020 (2) regarding quality clinical services for STIs a pathogen that causes infection through sexual contact, in primary care and STD specialty care settings. This guidance whereas the term “sexually transmitted disease” (STD) refers specifies operational determinants of quality services in various to a recognizable disease state that has developed from an clinical settings, describes on-site treatment and partner infection. Physicians and other health care providers have a services, and indicates when STI-related conditions should be crucial role in preventing and treating STIs. These guidelines managed through consultation with or referral to a specialist. are intended to assist with that effort. Although the guidelines emphasize treatment, prevention strategies and diagnostic recommendations also are discussed. This report updates Sexually Transmitted Diseases Treatment Methods Guidelines, 2015 (1) and should be regarded as a source of These guidelines were developed by CDC staff who worked clinical guidance rather than prescriptive standards. Health care with subject matter experts with expertise in STI clinical providers should always consider the clinical circumstances of management from other federal agencies, nongovernmental each person in the context of local disease prevalence. These academic and research institutions, and professional medical guidelines are applicable to any patient care setting that serves organizations. CDC staff identified governmental and persons at risk for STIs, including family planning clinics, nongovernmental subject matter experts on the basis of their HIV care clinics, correctional health care settings, private expertise and assisted them in developing questions to guide physicians’ offices, Federally Qualified Health Centers, clinics individual literature reviews. CDC staff informed the subject for adolescent care, and other primary care facilities. These matter experts that they were being consulted to exchange guidelines are focused on treatment and counseling and do information and observations and to obtain their individual not address other community services and interventions that input. All subject matter experts disclosed potential conflicts are essential to STI and HIV prevention efforts. of interest.

The “Five P’s” approach to obtaining a sexual history is one strategy for eliciting information about the key Primary prevention of STIs includes assessment of behavioral areas of interest (Box 1). In addition, health care professionals risk (i.e., assessing the sexual behaviors that can place persons can consider assessing sexual history by asking patients such at risk for infection) and biologic risk (i.e., testing for risk questions as, “Do you have any questions or concerns about markers for STI and HIV acquisition or transmission). As part your sexual health?” Additional information about gaining of the clinical encounter, health care providers should routinely cultural competency when working with certain populations obtain sexual histories from their patients and address risk (e.g., gay, bisexual, or other men who have sex with men reduction as indicated in this report.

Effective interviewing and counseling skills, comprehensive STI and HIV risk assessment should include characterized by respect, compassion, and a nonjudgmental STI screening as recommended in these guidelines because attitude toward all patients, are essential to obtaining a STIs are biologic markers of risk, particularly for HIV thorough sexual history and delivering effective prevention acquisition and transmission among certain MSM. In most messages. Effective techniques for facilitating rapport with clinical settings, STI screening is an essential and underused patients include using open-ended questions (e.g., “Tell me component of an STI and HIV risk assessment. Persons about any new sex partners you’ve had since your last visit” and seeking treatment or evaluation for a particular STI should be “What has your experience with using condoms been like?”); screened for HIV and other STIs as indicated by community understandable, nonjudgmental language (e.g., “What gender prevalence and individual risk factors (see Chlamydial are your sex partners?”and “Have you ever had a sore or scab Infections; Gonococcal Infections; Syphilis). Persons should on your penis?”); and normalizing language (e.g., “Some of my be informed about all the tests for STIs they are receiving and patients have difficulty using a condom with every sex act.

Efforts should counseling, videos and large group presentations can provide be made to ensure that all persons receive STI care regardless explicit information concerning STIs and reducing disease of personal circumstances (e.g., ability to pay, citizenship transmission (e.g., how to use condoms consistently and or immigration status, gender identity, language spoken, or correctly and the importance of routine screening). Group- specific sex practices). based strategies have been effective in reducing the occurrence of STIs among persons at risk, including those attending STI and HIV Infection STD clinics (9). Brief, online, electronic-learning modules for young MSM have been reported to be effective in reducing Prevention Counseling incident STIs and offer a convenient client platform for After obtaining a sexual history from their patients, all effective interventions (10). Because the incidence of certain providers should encourage risk reduction by offering STIs, most notably syphilis, is higher among persons with prevention counseling. Prevention counseling is most effective HIV infection, use of client-centered STI counseling for if provided in a nonjudgmental and empathetic manner persons with HIV continues to be encouraged by public health appropriate to the patient’s culture, language, sex and gender agencies and other health organizations (https://www.cdc.gov/ identity, sexual orientation, age, and developmental level. std/statistics/2019/default.htm). A 2014 guideline from CDC, Prevention counseling for STIs and HIV should be offered the Health Resources and Services Administration, and the to all sexually active adolescents and to all adults who have National Institutes of Health recommends that clinical and ✓ received an STI diagnosis, have had an STI during the nonclinical providers assess a person’s behavioral and biologic previous year, or ✓ have had multiple sex partners. USPSTF risks for acquiring or transmitting STIs and HIV, including recommends intensive behavioral counseling for all sexually having sex without condoms, having recent STIs, and having active adolescents and for adults at increased risk for STIs and partners recently treated for STIs (https://stacks.cdc.gov/ HIV (4). Such interactive counseling, which can be resource view/cdc/44064). That federal guideline is for clinical and intensive, is directed at a person’s risk, the situations in which nonclinical providers to offer or make referral for regular risk occurs, and the use of personalized goal-setting strategies. screening for multiple STIs, on-site STI treatment when One such approach, known as client-centered STI and HIV indicated, and risk-reduction interventions tailored to the prevention counseling, involves tailoring a discussion of risk person’s risks. Brief risk-reduction counseling delivered by reduction to the person’s situation. Although one large study in medical providers during HIV primary care visits, coupled STI clinics (Project RESPECT) demonstrated that this approach with routine STI screening, has been reported to reduce STI was associated with lower acquisition of curable STIs (e.g., incidence among persons with HIV infection (8). Other trichomoniasis, chlamydia, gonorrhea, and syphilis) (5), another specific methods have been designed for the HIV care setting study conducted 10 years later in the same settings but different (https://www.cdc.gov/hiv/effective-interventions/index.html). contexts (Project AWARE) did not replicate this result (6).

For protection from acquisition and transmission of STIs, although men and transgender women who have anal intercourse, data are limited. Internal condoms are more costly compared tenofovir gel appears safe when applied before and after anal with external condoms; however, they offer the advantage of sex (52). Spermicides containing nonoxynol-9 (N-9) might being controlled by the receptive partner as an STI and HIV disrupt genital or rectal epithelium and have been associated prevention method, and the newer versions might be acceptable with an increased risk for HIV infection. Condoms with N-9 to all persons. Although the internal condom also has been used are no more effective than condoms without N-9; therefore, during receptive anal intercourse, efficacy associated with this N-9 alone or in a condom is not recommended for STI and practice remains unknown (33).

However, a trial examining the effect Contraceptive methods that are not mechanical barriers of a diaphragm plus lubricant on HIV acquisition among offer no protection against HIV or other STIs. The ECHO women in Africa reported no additional protective effect when study observed no differences in HIV incidence rates among compared with the use of male condoms alone. Likewise, no women randomly assigned to DMPA, levonorgestrel implant, difference by study arm in the rate of acquisition of chlamydia, or copper-containing IUD contraceptive methods (38).

Whether hormonal contraception alters a woman’s risk Multipurpose Prevention Technologies for other STIs is uncertain (56,57). Methods that combine STI and HIV prevention Sexually active women who use contraceptive methods with pregnancy prevention are known as multipurpose other than condoms should be counseled about STI and HIV infection prevention measures. These include pre-exposure - prevention technologies (MPTs) (37) (https://www.who.int/ reproductivehealth/topics/linkages/mpts/en). Internal and prophylaxis (PrEP) and postexposure prophylaxis (PEP), external condoms are both examples of MPTs because they are limiting the number of sex partners, and correct and consistent effective prevention measures when used correctly for STI and use of condoms.

For persons who are being treated Clinicians should familiarize themselves with public health for an STI (or whose partners are undergoing treatment), practices in their area; however, in most instances, providers counseling that encourages abstinence from sexual intercourse should understand that responsibility for discussing the until completion of the entire course of medication is vital treatment of partners of persons with STIs rests with the for preventing reinfection.

Therefore, clinicians should encourage all persons with STIs to notify their sex partners and urge them The term “partner services” refers to a continuum of clinical to seek medical evaluation and treatment. Exceptions to this evaluation, counseling, diagnostic testing, and treatment practice include circumstances posing a risk for intimate designed to increase the number of infected persons brought to partner violence (111). Available data are limited regarding treatment and to reduce transmission among sexual networks. the rate of intimate partner violence directly attributable This continuum includes efforts of health departments, to partner notification (112,113); however, because of the medical providers, and patients themselves. The term “public reported prevalence of intimate partner violence in the general health partner services” refers to efforts by public health population (114), providers should consider the potential departments to identify the sex and needle-sharing partners risk before notifying partners of persons or encouraging of infected persons to ensure their medical evaluation and partner notification. Time spent counseling patients about the treatment. Health departments are increasingly incorporating importance of notifying partners is associated with improved referral to additional services, as indicated, into the partner services notification outcomes (115). When possible, clinicians should continuum. Aside from the general benefit to patients and partners, advise persons to bring their primary sex partner with them service referrals and linkage can mitigate the circumstances that when returning for treatment and should concurrently treat increase risk for future STI and HIV acquisition. both persons. Although this approach can be effective for a The types and comprehensiveness of public health partner main partner (116,117), it might not be a feasible approach services and the specific STIs for which they are offered vary for additional sex partners. Evidence indicates that providing by public health agency, their resources, and the geographic patients with written information to share with sex partners prevalence of STIs. In most areas of the United States, health can increase rates of partner treatment (110). departments routinely attempt to provide partner services to Certain health departments now use technology (e.g., all persons with infectious syphilis (primary or secondary) email, texting, mobile applications, and social media outlets) and persons with a new diagnosis of HIV infection. Health to facilitate partner services for locating and notifying the departments should provide partner services for persons who sex partners of persons with STIs, including HIV (118,119). might have cephalosporin-resistant gonorrhea. In contrast, Patients now have the option to use Internet sites to send relatively few U.S. health departments routinely provide anonymous email or text messages advising partners of their STI partner services to persons with gonorrhea, chlamydia, exposure to an STI (120); anonymous notification via the US Department of Health and Human Services/Centers for Disease Control and Prevention MMWR / July 23, 2021 / Vol. 70 / No. 4 9 Recommendations and Reports Internet is considered better than no notification at all. difference in the risk for reinfection or in the numbers of However, because the extent to which these sites affect partner partners treated between persons offered EPT and those notification and treatment is uncertain, patients should be advised to notify their sex partners (128).

No data support use of EPT in the routine Patients then provide partners with these therapies without management of patients with syphilis. the health care provider having examined the partner (https:// Data are limited regarding use of EPT for gonococcal www.cdc.gov/std/ept). Unless prohibited by law or other or chlamydial infections among MSM, compared with regulations, medical providers should routinely offer EPT heterosexuals (131,132). Published studies, including recent to patients with chlamydia when the provider cannot ensure data regarding extragenital testing, indicated that male partners that all of a patient’s sex partners from the previous 60 days of MSM with diagnosed gonorrhea or chlamydia might have will seek timely treatment. If the patient has not had sex other bacterial STIs (gonorrhea or syphilis) or HIV (133–135). during the 60 days before diagnosis, providers should offer Studies have reported that 5% of MSM have a new diagnosis EPT for the patient’s most recent sex partner. Because EPT of HIV when evaluated as partners of men with gonococcal must be an oral regimen and current gonorrhea treatment or chlamydial infections (133,134); however, more recent data involves an injection, EPT for gonorrhea should be offered indicate that, in certain settings, the frequency of HIV infection to partners unlikely to access timely evaluation after linkage is much lower (135). Considering limited data and potential is explored.
