Chlamydia is the most common reportable bacterial sexually transmitted infection in the United States, with approximately 1.6 million cases reported in 2020.
The highest rates of chlamydia infections in the United States are in females aged 15 to 24 year of age.
Chlamydia trachomatis frequently causes asymptomatic infection; it can also cause a wide range of clinical manifestations, including cervicitis, urethritis, pelvic inflammatory disease, infertility, and pelvic pain in women, as well as urethritis and epididymitis in men.
Less common manifestations in men and women may include conjunctivitis, oropharyngeal infection, proctitis or proctocolitis, and reactive arthritis.
Infants born to mothers with untreated C. trachomatis infection may develop conjunctivitis, trachoma, pneumonia, and urogenital infection.
Screening for chlamydia in asymptomatic persons significantly reduces the incidence of chlamydia-associated complications and is recommended in all sexually active women younger than 25 years of age, as well as in other persons at high risk of chlamydial infection.
In most circumstances, the preferred method to diagnose chlamydia is a NAAT, which is FDA-cleared for chlamydia testing on (1) male and female urine samples; (2) male and female rectal and throat samples; (3) clinician-collected endocervical, vaginal, and male urethral samples, and (4) self-collected vaginal swabs if obtained in a clinical setting.
For adults and adolescents, the recommended treatment for urogenital chlamydial infections in nonpregnant females and all males is a 7-day course of oral doxycycline 100 mg twice daily. The recommended treatment for pregnant females is 1 gram of oral azithromycin.
The diagnosis of LGV should be based on epidemiologic information, compatible clinical finding, and a positive C. trachomatis NAAT at the symptomatic anatomic site. The recommended treatment for LGV is a 21-day course of oral doxycycline 100 mg twice daily.
Recent sex partners of persons diagnosed with chlamydial infection should be referred for evaluation and presumptive treatment; expedited partner therapy should be considered in certain circumstances.

NGn the United States, rates of gonococcal infection have increased in recent years, especially among men who have sex with men. The age group with the highest gonorrhea rates is persons 20-24 years of age.
Gonococcal antimicrobial resistance to ceftriaxone remains low in the United States. Antimicrobial resistance to azithromycin has increased in recent years.
Gonorrhea is associated with increased susceptibility to HIV acquisition as well as an increased risk of HIV transmission.
Neisseria gonorrhoeae can cause a wide array of urogenital, pharyngeal, and rectal symptoms as well as serious complications, such as pelvic inflammatory disease, tubal infertility, ectopic pregnancy, neonatal conjunctivitis, and rarely, disseminated infection.
Screening for gonorrhea is recommended in sexually active women under 25 years of age and in other persons at increased risk of acquiring N. gonorrhoeae.
The NAAT is the preferred test for screening and diagnosing gonorrhea in both men and women. Culture is now primarily used when the concern for antimicrobial resistance arises.
Therapy with intramuscular ceftriaxone 500 mg is recommended in all persons (including pregnant women) with uncomplicated gonococcal infections of the cervix, urethra, rectum, or pharynx. If chlamydia infection has not been excluded, then concomitant treatment for chlamydia should be given with doxycycline 100 mg twice daily for 7 days; for pregnant individuals, a single 1-gram dose of oral azithromycin should be used instead of doxycycline to treat chlamydia.
A test-of-cure is not routinely recommended after treatment of uncomplicated infections of the cervix, urethra, and rectum, but it should be performed in all persons at 7 to 14 days following the treatment of pharyngeal gonorrhea.
Most cases of suspected treatment failures represent reinfection with N. gonorrhoeae, but if true cephalosporin treatment failure is suspected, clinicians should perform culture and sensitivity testing and seek expert consultation.
Persons who are diagnosed with gonorrhea should receive counseling about the nature of infection, the importance of partner notification, when they can resume sexual activity, and how they can reduce their risk for acquiring STIs in the future.

SYPHILLIS CONTAGION
Persons who acquire T. pallidum are contagious to their sex partners throughout the primary and secondary stages of infection—when lesions or rash are present.[14,16] Although sexual transmission of T. pallidum usually results from contact at genital mucous membranes, it can also occur at other body areas, including the mouth, anorectal areas, and cutaneous lesions.

SYPHILIS SUMMMARY
In the United States, reported cases of syphilis, including congenital syphilis, have steadily increased in recent years. Epidemiologic features associated with increased reported rates of syphilis include male sex, age 25-34 years, MSM, persons with HIV, and persons who are Black.
Syphilis is a systemic infection caused by Treponema pallidum, and in the absence of treatment, this disease can progress in stages. Untreated syphilis is characterized by episodes of active clinical manifestations interrupted by periods of asymptomatic latent infection. Neurosyphilis, ocular syphilis, and otosyphilis can occur during any stage of infection.
Untreated syphilis in pregnancy can lead to devastating consequences, including stillbirth, neonatal death, and congenital syphilis.
The laboratory diagnosis of syphilis is challenging and requires using a combination of clinical criteria and laboratory tests (both treponemal and nontreponemal tests) to differentiate active infection, prior infection, and absence of infection.
The serologic diagnosis of syphilis employs two major algorithms: (1) the traditional screening method that uses a nontreponemal assay as the initial test, or (2) a reverse sequence screening method that uses a treponemal antibody test as the initial test.
Screening for syphilis is recommended in all pregnant women, men who have sex with men, persons with HIV, and other groups at increased risk for acquisition of syphilis.
Penicillin G, administered parenterally, is the preferred drug for treating all stages of syphilis and is effective in resolving clinical symptoms associated with primary and secondary syphilis, as well as preventing late sequelae. The dosing of penicillin depends on the stage of disease; neurologic, ocular, and otosyphilis require more intensive therapy.
The Jarisch-Herxheimer reaction is a self-limited reaction that can occur after initiation of anti-treponemal therapy; it is characterized by fever, malaise, nausea, vomiting, chills, and exacerbation of a secondary syphilis rash.
For a person diagnosed with primary, secondary, or early latent syphilis, all of their sex partners within the prior 90 days should undergo evaluation and treatment of syphilis; if no sexual contacts occurred in the 90 days prior to the diagnosis, then the most recent sex partner should have evaluation and presumptive treatment.
All persons treated for syphilis should have follow-up monitoring with nontreponemal testing to evaluate response to treatment.

Optimize the management of other concurrent illnesses, such as diabetes mellitus and HIV.
The three most common conditions diagnosed among women with vaginal symptoms presenting in the primary care setting are bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis.
The normal vagina has abundant and dominant Lactobacillus species and a pH that is less than 3.8 to 4.5.
Vaginitis is primarily a clinical diagnosis, but a wide variety of diagnostic tests are available, including point-of-care tests, culture, molecular detection methods (PCR, NAAT), and indirect testing for enzymatic activity.
Women with symptomatic bacterial vaginosis typically present with a homogenous, white or gray vaginal discharge that often has a “fishy” odor. Bacterial vaginosis has been linked to several obstetrical and gynecologic complications.
The preferred treatments for bacterial vaginosis are oral metronidazole (500 mg twice daily for 7 days), 0.75% metronidazole gel (5 grams applied intravaginally once daily for 5 days), or intravaginal 2% clindamycin cream (5 grams applied intravaginally at bedtime for 7 days).
Women with symptomatic trichomoniasis usually have a characteristic “frothy” gray or yellow-green vaginal discharge and pruritus. Trichomoniasis increases the risk of premature rupture of membranes and preterm labor.
The preferred treatment for trichomoniasis in women is a 7-day course of oral metronidazole (500 mg twice daily); for men, the preferred treatment is a single 2-gram dose of oral metronidazole.
Vulvovaginal candidiasis characteristically presents with symptoms of pruritus, vaginal soreness, dyspareunia, vulvar burning, external dysuria, and abnormal vaginal discharge.
Vulvovaginal candidiasis is classified as either uncomplicated or complicated based on clinical presentation, host immunity, and pathogen factors.
Uncomplicated vulvovaginal candidiasis can be treated with a wide array of short-course topical antifungal agents or a single 150 mg dose of oral fluconazole.

HSV PATIENT EDUCATION
When counseling persons with symptomatic HSV-2 genital herpes infection, the provider should discuss the following:
The natural history of the disease, with emphasis on the potential for recurrent episodes, asymptomatic viral shedding, and the attendant risks for sexual transmission of HSV to occur during asymptomatic periods (asymptomatic viral shedding is most frequent during the first 12 months after acquiring HSV-2).
The effectiveness of daily suppressive antiviral therapy for preventing symptomatic recurrent episodes of genital herpes for persons experiencing a first episode or recurrent genital herpes.
The effectiveness of daily use of valacyclovir in reducing risk for transmission of HSV-2 among persons without HIV and use of episodic therapy to shorten the duration of recurrent episodes.
The importance of informing current sex partners about genital herpes and informing future partners before initiating a sexual relationship.
The importance of abstaining from sexual activity with uninfected partners when lesions or prodromal symptoms are present.
The effectiveness of male latex condoms, which when used consistently and correctly can reduce, but not eliminate, the risk for genital herpes transmission.
The type-specific serologic testing of partners of persons with symptomatic HSV-2 genital herpes to determine whether such partners are already HSV seropositive or whether risk for acquiring HSV exists.
The low risk for neonatal HSV except when genital herpes is acquired late in pregnancy or if prodrome or lesions are present at delivery.
The increased risk for HIV acquisition among HSV-2 seropositive persons who are exposed to HIV.
The lack of effectiveness of episodic or suppressive therapy among persons with HIV to reduce risk for transmission to partners who might be at risk for HSV-2 acquisition.
HSV OVERALL SUMMARY
Genital herpes is the leading cause of genital ulcer disease worldwide and one of the most prevalent sexually transmitted infections in the United States.
Genital herpes is a chronic viral infection predominantly caused by HSV-2; it is characterized by periods of latency punctuated by periods of viral shedding.
More than 85% of persons with genital herpes are unaware of their infection, and asymptomatic shedding of HSV accounts for most transmitted genital HSV infections.
To make a clinical diagnosis of genital herpes, a direct viral test (preferably PCR) should be performed on a sample taken from a lesion.
Routine serologic screening for genital herpes is not recommended for the general population, but type-specific serologic screening for HSV-2 may be indicated in certain situations.
When type-specific serologic testing is indicated, a two-step process should be utilized to confirm low index value (less than or equal to 3.0) on initial EIA-ENZYME IMMUNOSASSAY -LOOKS FOR ANTIBODIES or CLIA testing.
Antiviral therapy with acyclovir, valacyclovir, or famciclovir can be used intermittently for each episode of genital herpes (episodic therapy) and to prevent recurrent outbreaks (suppressive therapy).
Among persons without HIV, daily suppressive therapy with valacyclovir prevents recurrent outbreaks of genital herpes and reduces transmission of HSV-2 to sex partners.
Prophylactic therapy with acyclovir or valacyclovir beginning at 36 weeks of gestation should be offered to all women with a history of genital herpes since it has been shown to reduce the risk of HSV recurrence at delivery and thereby reduce the need for a cesarean delivery.
Counseling plays an integral role in the management of a patient diagnosed with HSV infection, given the significant morbidity attributed to the psychological burden of HSV related to the need for behavior change and for disclosure to sexual partners.
