Abstract
INTRODUCTION Every days, more than one million people are infected with a sexually transmitted infection worlwide. In France, screening mainly rely on medical laboratories, private or public, with e prescription. Those tests face structural ans social barriers for LGBT people that could be partially lifted using at home self sampling. Using a narrative review, we will study how the needs of those populations are adressed in existing at home self sampling interventions. PURPOSE OF RESEARCH Describe the adaptation of home sampling system to MSM, WSW and transgender peoples. RESULTS Nine interventions met our inclusion criteria, eight in English spoken countries. Studies did not systematically reported data on sexual orientation. Transgender people, when identified, were rarely a larger group enough to be the subject of sub-analysis. Infections tested were CT and NG for three intervention, HIV only for one, CT,NG and HIV for five, and one also add HCV. CONCLUSIONS Standing as a complement to physical testing services, at home self-sampling intervention could benefit from an advertisement to WSW and from the integration of wider sexual health services.

Abstract
Background COVID‐19 has impacted delivery of outpatient gynecology and shifted care toward use of telemedicine. Objective To rapidly review literature and society guidelines and create expert consensus to provide guidance regarding management of outpatient gynecology scenarios via telemedicine. Search strategy Searches were conducted in Medline and Cochrane databases from inception through April 15, 2020. Selection criteria Literature searches were conducted for articles on telemedicine and abnormal uterine bleeding, chronic pelvic pain, endometriosis, vaginitis, and postoperative care. Searches were restricted to available English language publications. Data collection and analysis Expedited literature review methodology was followed and 10 943 citations were single‐screened. Full‐text articles and relevant guidelines were reviewed and narrative summaries developed. Main results Fifty‐one studies on the use of telemedicine in gynecology were found. Findings were reported for these studies and combined with society guidelines and expert consensus on four topics (abnormal uterine bleeding, chronic pelvic pain and endometriosis, vaginal discharge, and postoperative care). Conclusions Guidance for treating gynecological conditions via telemedicine based on expedited literature review, review of society recommendations, and expert consensus is presented. Due to minimal evidence surrounding telemedicine and gynecology, a final consensus document is presented here that can be efficiently used in a clinical setting. Guidance for gynecologists using telemedicine during COVID‐19 based on rapid literature review, review of society recommendations, and expert consensus in accessible format.

Abstract
A large sample (n = 77,740) of men and women tested for Trichomonas vaginalis showed increasing age-dependent infection rates for both sexes, suggesting that older men and older women should be screened for this sexually transmitted infection. Men and women attending family planning and sexually transmitted disease clinics for sexually transmitted infection screening in 2012 to 2013 were tested for Trichomonas vaginalis (TV) using a sensitive nucleic acid amplification test. T. vaginalis prevalence in urogenital samples was 11.3% in 77,740 women and 6.1% in 12,604 men, and increased with age in both sexes.

Abstract
Background The epidemiology of Trichomonas vaginalis (TV) infection in the United States is poorly defined. Methods Males and females aged 18-59 years who participated in the 2013-2014 National Health and Nutrition Examination Survey and provided a urine specimen were tested for TV infection (n = 4057). Participants were also examined for Chlamydia trachomatis (CT) infection, genital human papillomavirus (HPV) infection, and herpes simplex virus type 2 serostatus. Weighted adjusted prevalence ratios (aPRs) were estimated by multivariable Poisson regression. Results TV infection prevalence was 0.5% and 1.8% among males and females, respectively. TV infection prevalence was 4.2% among black males, 8.9% among black females, and 0.03% and 0.8%, respectively, among males and females of other races/ethnicities. TV infection prevalence (aPR [95% confidence interval]) was positively associated with female sex (6.1 [3.3-11.3]), black race (vs other races/ethnicities; 7.9 [3.9-16.1]), older age (vs 18-24 years; 3.0 [1.2-7.1] for 25- to 39-year-olds and 3.5 [1.3-9.4] for 40- to 59-year-olds), having less than a high school education (vs completing high school or more; 2.0 [1.0-4.1]), being below the poverty level (vs at or above the poverty level; 4.0 [2.1-7.7]), and having ≥2 sexual partners in the past year (vs 0-1 sexual partners; 3.6 [2.0-6.6]). There were no TV and CT coinfections. Genital HPV detection was not independently associated with TV infection. Among persons aged 18-39 years, there was a significant racial disparity in all sexually transmitted infections examined, and this disparity was greatest for TV infection. Conclusions There is a high and disproportionate burden of urinary TV infection in the adult civilian, noninstitutionalized black population in the United States that warrants intervention.

Abstract
BACKGROUND Trichomonas vaginalis is the most common nonviral sexually transmitted infection. T. vaginalis nucleic acid amplification testing (NAAT) recently became available at the University of Alabama at Birmingham human immunodeficiency virus (HIV) clinic. The objective of this study was to determine the uptake of T. vaginalis NAAT testing among clinic providers during the first year of test availability in addition to T. vaginalis prevalence and predictors based on NAAT results. METHODS This was a retrospective review of HIV+ women and men ages ≥16 years at the University of Alabama at Birmingham HIV Clinic, including those receiving a T. vaginalis NAAT on a genitourinary specimen. RESULTS Between August 2014 and August 2015, 3163 HIV+ patients were seen (768 women, 2395 men), of whom 861 (27.3%) received a T. vaginalis NAAT; 402 women (52.3%) and 459 men (19.2%). Among those with T. vaginalis NAAT results, 70 (17.4%) of 402 women and 12 (2.6%) of 459 men (9 men who have sex with women, 1 man who has sex with men, 2 unknown) tested positive. In adjusted analyses for women, age ≤40 years (odds ratio [OR], 2.93; 95% confidence interval [CI], 1.23-6.96), current cocaine use (OR, 4.86; 95% CI, 1.57-15.06), and CD4 < 200 cells/mm (OR, 6.09; 95% CI, 1.68-22.11) were significantly associated with increased odds of a positive T. vaginalis NAAT. For those with a positive T. vaginalis NAAT, treatment was prescribed for 65 (92.9%) of 70 women and 10 (83.3%) of 12 men. CONCLUSIONS Initial uptake of T. vaginalis NAAT testing was modest at this HIV clinic yet identified a high prevalence among women tested. Emphasis on the need for testing in HIV+ women is necessary.

Abstract
Our previous pilot study during 2010-2013, based on the IWantTheKit (IWTK) home self-collection program for sexually transmitted infections (STIs), showed that voluntary risk score tool predicted STIs well in female volunteers compared to their male counterparts. Risk score became a required part of the IWTK program in August 2013. We investigated association of IWTK risk score and presence of STI in 592 male participants living in Maryland and Washington DC from August 2013 to April 2015. The risk score quiz includes questions on demographic and sexual risk behavior. Data were analyzed using the Cochran-Armitage test for trend to determine if prevalence of STIs (Chlamydia, gonorrhea, or trichomoniasis) increased with the higher risk score category. Overall, 57% of participants were aged < 30 years (mean: 30.1 ± 9.3 years); 42% white, 42% black, and 16% other races. The majority (67%) of participants had medium risk scores of 3-6, followed by high scores of 7-10 (22%), and 0-2 (11%). The overall prevalence of STIs was 10.5% (62/592). The prevalence of STIs was 3.1% for users with risk scores of 0-2, 10.4% for those with scores 3-6, and 14.3% for those with scores 7-10 (trend test: p = 0.019). Medium and high IWTK risk scores successfully predicted the probability of STIs in male participants after elimination of potential selection biases.

Abstract
Ureaplasma urealyticum and U. parvum have been associated with genital infections. The purpose of this study was to detect the presence of ureaplasmas and other sexually transmitted infections in sexually active women from Brazil and relate these data to demographic and sexual health, and cytokines IL-6 and IL-1β. Samples of cervical swab of 302 women were examined at the Family Health Units in Vitória da Conquista. The frequency of detection by conventional PCR was 76·2% for Mollicutes. In qPCR, the frequency found was 16·6% for U. urealyticum and 60·6% U. parvum and the bacterial load of these microorganisms was not significantly associated with signs and symptoms of genital infection. The frequency found for Trichomonas vaginalis, Neisseria gonorrhoeae, Gardnerella vaginalis and Chlamydia trachomatis was 3·0%, 21·5%, 42·4% and 1·7%, respectively. Higher levels of IL-1β were associated with control women colonized by U. urealyticum and U. parvum. Increased levels of IL-6 were associated with women who exhibited U. parvum. Sexually active women, with more than one sexual partner in the last 3 months, living in a rural area were associated with increased odds of certain U. parvum serovar infection.

Abstract
Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million women and men in the United States. Health disparities are prominent in the epidemiology of this infection, which affects 11% of women aged ≥40 years and a disproportionately high percentage of black women. Particularly high prevalences have been identified among sexually transmitted disease (STD) clinic patients and incarcerated individuals. This article reviews and updates scientific evidence in key topic areas used for the development of the 2015 STD Treatment Guidelines published by the Centers for Disease Control and Prevention. Current evidence is presented regarding conditions associated with Trichomonas vaginalis infection, including human immunodeficiency virus (HIV) and pregnancy complications such as preterm birth. Nucleic acid amplification tests and point-of-care tests are newly available diagnostic methods that can be conducted on a variety of specimens, potentially allowing highly sensitive testing and screening of both women and men at risk for infection. Usually, trichomoniasis can be cured with single-dose therapy of an appropriate nitroimidazole antibiotic, but women who are also infected with HIV should receive therapy for 7 days. Antimicrobial resistance is an emerging concern.

Abstract
BACKGROUND Individuals who are sexually active may want to make a decision as to whether they are at risk for having a sexually transmitted infection (STI) such as Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis. Our goal was to develop and evaluate a simple self-taken sexual risk quiz for participants, ordering an online STI self-collection test kit to determine whether the score predicted infection status. METHODS As part of the IWantTheKit programme for home sample self-collection for STIs, 2010-2013, the programme asked male and female users to voluntarily take a risk quiz. The six-question quiz was about risk behaviour and included an age question. Data analyses were stratified by gender as determined a priori. Scores 0-10 were stratified into risk groups for each gender based on similar risk score-specific STI prevalence. Retrospective analyses were performed to assess whether risk group predicted aggregate STI positivity. Urogenital/rectal mailed samples were tested by nucleic acid amplification tests. RESULTS More females (N=836) than males (N=558) provided voluntary risk scores. The percentage of eligible participants who submitted scores was 43.9% for both females and males. There was a higher STI infection rate in females (14.0%) than in males (7.0%) for having any STI (p<0.001). Multivariate logistic analysis for females, which controlled for age and race, demonstrated that a higher risk score group independently predicted risk for having an STI (OR of 2.2 for risk scores 5-7 and 4.2 OR for scores of 8-10). For males, the multivariate model, which controlled for race, indicated that no risk score group was associated having an STI. CONCLUSIONS Results of a participant's own sexual risk quiz score independently predicted STI positivity for women, but not for men. Further study of this simple risk quiz is required.

Abstract
Guidelines for screening of cervical cancer and pelvic exams for older women have recently changed. These changes may have unexpected sequelae in women over 65 years of age. This manuscript provides a review of gynecologic screening recommendations for older women in the U.S. and potential ramifications of these recent changes. Peer reviewed guidelines from the American College of Obstetrics and Gynecology, U.S. Preventative Task Force Services, the American Cancer Society, The Centers for Disease Control, and multiple original research articles and reviews were reviewed for this manuscript. Women over 65 are at greatest risk to develop late stage diagnoses of cancers, pelvic organ disease, incontinence, and infections. Clinicians will need to acutely consider this fact when communicating and screening this population. We conclude that practitioners should be aware of the new guidelines and should consider including gynecologic health history and symptom analysis as part of annual exams in women of all ages.

Abstract
American Indians suffer a disproportionate burden of sexually transmitted infection, particularly adolescents. Screening access barriers in rural and reservation-based communities necessitate alternatives to clinic-based options. Self-administered screening for three sexually transmitted infections was piloted among 32 American Indian adolescents aged 18 to 19. Participants self-collected in a private location; specimens were processed by trained, American Indian paraprofessionals and analysis was conducted by an outside laboratory. Participants testing positive were treated by a Public Health Nurse from the Indian Health Service. Results suggest high overall acceptability: 69% preferred a self-administered method over clinic-based screening, 75% would encourage their friends to use this method and 100% would use it again. A self-administered screening method has the ability to reach this and other high-risk populations that might not otherwise access screening, with added potential within the Indian Health Services system for uptake and dissemination in rural, reservation communities facing significant screening barriers.

Abstract
Remnant specimen from 1215 women screening for chlamydia/gonorrhea at 4 different venue types (sexually transmitted disease clinics, home-test kit users, juvenile and adult detention) in Los Angeles, California, were tested for Trichomonas vaginalis. Prevalence of T. vaginalis varied by screening population, and concurrent chlamydia or gonorrhea was independently associated with T. vaginalis.

Abstract
Trichomonas vaginalis is one of the most common human parasitic infections in the United States, as well as the most prevalent non-viral sexually transmitted infection. However, it has long received much less consideration than other parasitic and sexually transmitted diseases. Much of this inattention can be attributed to a poor understanding of the public health impact of trichomoniasis. Increasing recognition of the sequelae of infection, including increased risk of infection with human immunodeficiency virus and adverse outcomes of pregnancy, has led to increased interest in T. vaginalis. Recent innovations include development of diagnostic tests that could improve detection of the parasite. A number of important questions, such as the epidemiology among men and women, the true public health burden of symptomatic and asymptomatic T. vaginalis infections, and whether current treatments will be adequate to reduce the substantial health disparities and costs associated with trichomoniasis, need consideration to remedy neglect of this important disease.

Abstract
In the UK, despite its low sensitivity, wet mount microscopy is often the only method of detecting Trichomonas vaginalis infection. A study was conducted in symptomatic women to compare the performance of five methods for detecting T. vaginalis: an in-house polymerase chain reaction (PCR); Aptima T. vaginalis kit; OSOM ®Trichomonas Rapid Test; culture and microscopy. Symptomatic women underwent routine testing; microscopy and further swabs were taken for molecular testing, OSOM and culture. A true positive was defined as a sample that was positive for T. vaginalis by two or more different methods. Two hundred and forty-six women were recruited: 24 patients were positive for T. vaginalis by two or more different methods. Of these 24 patients, 21 patients were detected by real-time PCR (sensitivity 88%); 22 patients were detected by the Aptima T. vaginalis kit (sensitivity 92%); 22 patients were detected by OSOM (sensitivity 92%); nine were detected by wet mount microscopy (sensitivity 38%); and 21 were detected by culture (sensitivity 88%). Two patients were positive by just one method and were not considered true positives. All the other detection methods had a sensitivity to detect T. vaginalis that was significantly greater than wet mount microscopy, highlighting the number of cases that are routinely missed even in symptomatic women if microscopy is the only diagnostic method available.

Abstract
BACKGROUND Internet-based screening for vaginal sexually transmitted infections (STI) has been shown to reach high-risk populations. Published studies of internet-based screening for rectal STIs in women are needed. Our objectives were to describe the female users of a rectal internet-based screening intervention and assess what factors correlated with rectal positivity for STIs. METHODS The website http://www.iwantthekit.org offers free STI testing via home self-sampling kits. Women could order vaginal and rectal kits, both containing questionnaires. Rectal and vaginal swabs were tested for Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis using nucleic acid amplification tests. Data were analysed from 205 rectal kits from January 2009 through February 2011. Self-reported characteristics of participants were examined, and correlates of rectal STI positivity were analysed. RESULTS Of the 205 rectal samples returned and eligible for testing, 38 (18.5%) were positive for at least one STI. The women were young (mean age 25.8 years), mostly African-American (50.0%), and only 14.0% always used condoms. After adjusting for age and race, Black race (AOR=3.06) and vaginal STI positivity (AOR=40.6) were significantly correlated with rectal STI positivity. Of women testing positive for rectal STIs who also submitted vaginal swabs, 29.4% were negative in the vaginal sample. CONCLUSIONS Internet-based rectal screening can reach populations that appear to be at high risk for rectal STIs (18.5% prevalence) and led to the diagnosis of STIs in women who would not have been diagnosed vaginally. Black race and vaginal STI positivity were highly correlated with rectal STI positivity.

Abstract
Professional organizations recommend rescreening chlamydia-infected women. The iwantthekit Internet-screening programme offered rescreening opportunities by using iwantthekit. Mailed, home-collected vaginal swabs were tested for chlamydia, gonorrhoea, and trichomoniasis by nucleic acid amplification tests. Demographics and risk behaviours of repeat users were determined from questionnaires. Predictors of repeat users were measured in a matched case-control study. Of 1747 women, 304 (17%), who used iwantthekit, indicated they had used the kit previously. Mean age was 24.7 ± 5.7 years and 69% were African-American. Repeat iwantthekit users were more likely to be aged ≥ 20 years (OR=2.10); were more likely to have been treated for a sexually transmitted infection (OR=2.32); less likely to drink alcohol before sex (OR=0.63); and to never use condoms (OR=0.43). Of repeat users, 84.2% had a negative prior test and 15.8% had a positive. At current test, 13.2% were infected. Previous trichomoniasis was associated with current trichomoniasis (p<0.05). The iwantthekit may offer rescreening opportunities for previously infected women.

Abstract
BACKGROUND Trichomonas vaginalis is the most prevalent curable sexually transmitted infection in the United States and may lead to preterm delivery, infertility, and increased HIV transmission. Incarcerated women may be at especially high risk for infection, although few studies have examined routine screening for Trichomonas infection in this population. METHODS Women older than 18 years entering the Rhode Island Department of Corrections between September 2009 and May 2011 were recruited to participate. All women submitted a self-collected vaginal swab for APTIMA transcription-mediated amplification testing. Each participant completed a survey addressing demographics, symptoms, sexual behavior, and substance use by audio computer-assisted self-interview. Data analysis was completed using multivariate logistic regression in SAS. RESULTS Data for 387 women were analyzed. The mean age was 30 years, 60% were white, 18% were Hispanic, 10% were black, and 12% had other race/ethnicity. Forty-four percent reported vaginal symptoms, and 77% reported illicit drug and/or heavy alcohol use in the 30 days before incarceration. The prevalence of Trichomonas was 14% by APTIMA. The strongest predictors of infection included black race (odds ratio [OR], 5.1; 95% confidence interval [CI], 1.9-13.4; P < 0.01), more than 1 year since last Papanicolaou test (OR, 2.5; 95% CI, 1.3-4.8; P < 0.01) and presence of vaginal symptoms (OR, 2.3; 95% CI, 1.2-4.7; P = 0.02). CONCLUSIONS Trichomonas infection is common in incarcerated women, especially among black women, women with vaginal symptoms, and those not receiving routine gynecologic care. Screening for Trichomonas infection in high-risk populations, particularly if using highly sensitive methods such as transcription-mediated amplification, may lead to increased detection and treatment.

Abstract
Recent advances in tests for the sexually transmitted protozoan parasite Trichomonas vaginalis have increased opportunities for diagnosis and treatment of this important sexually transmitted infection. This review summarises currently available tests, highlighting their performance characteristics, advantages and limitations. The recent development of molecular tests for the detection of T vaginalis, including rapid antigen detection and nucleic acid amplification tests, has significantly improved the quality of diagnostics for trichomoniasis, particularly in women. In light of the expanded menu of testing options now available, improved recognition and better control of trichomoniasis are in sight, which should enable the eventual reduction of adverse reproductive consequences associated with T vaginalis infection.

Abstract
OBJECTIVE Trichomoniasis vaginalis is a risk factor for the acquisition and transmission of HIV. The objective of this study was to determine the prevalence of T vaginalis (using culture) among HIV-infected women receiving gynaecological care at an university HIV clinic in Alabama in addition to predictors of infection. METHODS Electronic medical record review of women presenting to the clinic for gynaecological care during 2006-2012 was performed. Demographic and sexual history data was abstracted in addition to absolute CD4 cell count, HIV-1 viral load and sexually transmitted infection (STI) (including T vaginalis) testing results. Analysis was conducted using Stata V.12. RESULTS T vaginalis was prevalent in 17.4% (83/478) of HIV-infected women; other STIs were less prevalent. Among these women, 384 presented for routine STI screening, of which 12% (46/384) were T vaginalis-infected. Younger age, African-American race, lifetime history of tobacco and drug abuse, lack of HIV therapy, HIV-1 viral load >400 copies/ml, and report of seeking gynaecological care for reasons other than routine STI screening (ie, having symptoms) were significant predictors of T vaginalis in univariate analysis. Age, African American race, and report of seeking gynaecological care for reasons other than routine STI screening remained associated with T vaginalis in multivariable analysis. CONCLUSIONS T vaginalis remains highly prevalent among HIV-infected women, a proportion of which may be asymptomatic. If left undiagnosed and untreated, these women may be more likely to transmit HIV. Increased emphasis on screening for high risk sexual behaviours, testing for T vaginalis, and risk reduction counselling is necessary for all HIV-infected women.

Abstract
BACKGROUND Submission of self-collected penile samples collected at home could remove barriers that men face in getting tested for sexually transmitted infections (STIs). METHODS From December 2006 to July 2012, sexually active men aged ≥14 years were recruited by an educational internet program (http://www.iwantthekit.org) which offered free testing for Trichomonas vaginalis infection. Kits were ordered online and swabs were sent via US mail to the laboratory and tested by nucleic acid amplification tests. Demographics and sexual risk factors were accessed by questionnaires. Men called or were contacted to receive their results. Risk factors for trichomonas infection were determined by multivariate logistic regression RESULTS Of 4398 men requesting kits, 1699 (38.6%) returned swabs by mail (55.4% returned in 2012). Forty-one percent of men were aged <25 years, 43% were black subjects and 45% were white. The overall prevalence for trichomonas in the 1699 men was 3.7%; the highest prevalence by age group was for men aged 40-49 years (5.2%) and, by year, 216 men screened in 2008 had the highest prevalence (12.5%). Risk factors for 919 men whose risk information was collected by questionnaire (prevalence 6.0%) indicated that 9.6% had a concurrent chlamydia infection. Significantly associated risks factors included: black race (adjusted OR 2.67), residence in Illinois (OR 12.02), age 30-39 years (OR 6.63) and age >40 years (OR 5.31). CONCLUSIONS A fairly high prevalence of trichomonas and sexual risk factors were demonstrated from internet recruitment of men. This method of engaging men to get screened for trichomonas may augment screening in STI clinics.

Abstract
Our aim was to determine Trichomonas vaginalis prevalence using the Aptima Trichomonas vaginalis assay (ATV; Gen-Probe) and the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae coinfections in U.S. women undergoing screening for C. trachomatis/N. gonorrhoeae. Discarded urogenital samples from 7,593 women (18 to 89 years old) undergoing C. trachomatis/N. gonorrhoeae screening using the Aptima Combo 2 assay (Gen-Probe) in various clinical settings were tested with ATV. Overall, T. vaginalis, C. trachomatis, and N. gonorrhoeae prevalences were 8.7%, 6.7%, and 1.7%, respectively. T. vaginalis was more prevalent than C. trachomatis or N. gonorrhoeae in all age groups except the 18- to 19-year-old group. The highest T. vaginalis prevalence was in women ≥ 40 years old (>11%), while the highest C. trachomatis prevalence (9.2%) and N. gonorrhoeae prevalence (2.2%) were in women <30 years old. Coinfection prevalences were 1.3% for C. trachomatis/T. vaginalis, 0.61% for C. trachomatis/N. gonorrhoeae and N. gonorrhoeae/T. vaginalis, and 0.24% for C. trachomatis/N. gonorrhoeae/T. vaginalis and highest in women <30 years old. T. vaginalis prevalence differed by race/ethnicity, with the highest prevalence in black women (20.2%). T. vaginalis prevalence ranged from 5.4% in family planning clinics to 22.3% in jails. Multivariate analysis determined that ages of ≥ 40 years, black race, and patient locations were significantly associated with T. vaginalis infection. T. vaginalis is the most common sexually transmitted infection (STI) in women of >40 years, while C. trachomatis and N. gonorrhoeae prevalence is lowest in that age group. Higher T. vaginalis prevalence in women of >40 years is probably attributed to the reason for testing, i.e., symptomatic status versus routine screening in younger women. Coinfections were relatively low. High T. vaginalis prevalence in all age groups suggests that women screened for C. trachomatis/N. gonorrhoeae, whether asymptomatic or symptomatic, should be screened for T. vaginalis.

Abstract
Dry-shipped and mailed vaginal swabs collected at home have been used in research studies for the detection of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC), and Trichomonas vaginalis (TV) by nucleic acid amplification tests (NAATs) in screening programs. A verification study was performed to compare the limit of detection of CT, GC, and TV on swabs that were dry-shipped to paired swabs that were wet-shipped in transport media through the US mail. The Centers for Disease Control and Prevention prepared inocula in sterile water to mock simulated urogenital swabs with high to low concentrations of CT and GC. Replicate swabs were inoculated with 100 μL of dilutions and were dry transported or placed into commercial transport media ("wet") for mailing for NAAT testing. The University of Alabama prepared replicate concentrations of TV, which were similarly shipped and tested by NAAT. All paired dry and wet swabs were detectable for CT. For GC, all paired dry and wet swabs were detectable for GC at concentrations ≥ 10(3). At 10(2) and 10 CFU/mL, the 10 replicate GC results were variably positive. For TV, wet and dry shipped concentrations >10(2) TV/mL tested positive, while results at 10 TV/mL were negative for dry swabs. Holding replicate dry swabs at 55 (○)C 5 days before testing did not affect results. NAATs were able to detect CT, GC, and TV on dry transported swabs. Using NAATs for testing home-collected, urogenital swabs mailed in a dry state to a laboratory may be useful for outreach screening programs.

Abstract
The Internet is a relatively new tool in the surveillance and prevention of sexually transmitted infections, and this review examines its global use in this regard. Much use has been made in the form of information collection and dissemination; targeted population engagement through chat rooms, partner notification and other mechanisms; and the provision of testing services and other products. Internet users may need education concerning reputable websites, and public health practitioners need proficiency in the use of social media and marketing.
