OBJECTIVES: To determine the prevalence of the most important sexually transmitted infections among women of child bearing age in Jordan. GOAL: To assess the need for screening programs to detect sexually transmitted infections. STUDY DESIGN: This is a cross-sectional study wherein consecutive symptomatic and asymptomatic women presenting to gynecology and family planning clinics from different areas in Jordan were tested for reproductive tract infections caused by Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, and Trichomonas vaginalis. RESULTS: The prevalence of C. trachomatis infection was 0.6% and 0.5%, among symptomatic and asymptomatic women respectively, that of N. gonorrhoeae was 0.9% and 2.2%, that of T. pallidum 0.0% and 0.0%, and that of Tr. vaginalis was 0.7% and 0.5%. These prevalence rates did not differ significantly between symptomatic and asymptomatic women. CONCLUSIONS: Based on the low prevalence of sexually transmitted infections detected in this study among Jordanian women, the need for screening programs for such infections is questioned. 相似文献

INTRODUCTION: The aim of this study was to assess the prevalence of sexually transmitted infections among patients attending an anonymous HIV Screening Center. PATIENTS AND METHODS: This prospective study was performed in the HIV Screening Center of University hospital in Reims (France) from May 1997 to December 1997. The inclusion criteria were the asymptomatic clinical presentation and the presence of risk factors for sexually transmitted infections referring to WHO criteria. The methods included clinical examination after application of acetic acid and urethral and endocervical swabs to identify:Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Gardnerella vaginalis, Trichomonas vaginalis in specific culture. Treponema pallidum and HIV-1 infection were both detected by Enzym Linked Immuno Sorbent Assay (ELISA). RESULTS: One hundred and one patients (62 men and 39 women) were included in the study. Their mean age was 27 +/- 4 Years. Risk factors for sexually transmitted infections were: multiple sexual partners 81 p. 100; homo or bisexuality 16 p. 100; intravenous drug use 3 p. 100. The sexually transmitted infections were: HIV-1 infection 1 p. 100;Ureaplasma urealyticum 25 p. 100; genital warts 5 p. 100;Chlamydia trachomatis 3 p. 100; Gardnerella vaginalis 3 p. 100; Mycoplasma hominis 2 p. 100; Treponema pallidum 0 p. 100; Neisseria gonorrhoeae 0 p. 100; Trichomonas vaginalis 0 p. 100. The prevalence of sexually transmitted infections was significantly higher among women (p<0.05). DISCUSSION: Classical sexually transmitted infections and HIV infection were rarely detected in this study; but prevalence of other sexually transmitted infections (genital warts, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum) was high. Ureaplasma urealyticum is considered as a possible pathogenic agent in pregnant women (preterm delivery, decrease of birth weight, chorioamniotitis). These results suggest that other than sexually transmitted infections in high risk patients attending a HIV Screening Center other sexually transmitted infections should also be systematically screened for. 相似文献

OBJECTIVE--To determine the association of sexually transmitted pathogens in women with cervical intra-epithelial neoplasia (CIN). SETTING--An urban tertiary referral hospital serving a large indigent developing community. PARTICIPANTS--48 women attending a colposcopy clinic and 49 women attending a family planning clinic. METHODS--Vaginal, endocervical, rectal swab specimens and sera were collected for the detection of sexually transmitted pathogens. Cervical cytology was performed on all patients. Women attending the colposcopy clinic had confirmation of abnormal cervical cytology by colposcopic directed biopsy. RESULTS--The mean age of women with CIN (33 years) was significantly greater than that of the women without CIN (28 years) and that of the family planning group (26 years). There was a high prevalence of sexually transmitted pathogens in all women. A significantly higher prevalence of bacterial vaginosis was found in women with CIN compared to those without (50% vs 20%; p = 0.034). The human papilloma virus (HPV) was detected in 46% of women with CIN and 65% of those without CIN. Chlamydia trachomatis (21%) and Trichomonas vaginalis (39%) were detected frequently in women with CIN. C. trachomatis (14%-21%) was detected more frequently than Neisseria gonorrhoeae (3-5%) in all asymptomatic women studied. CONCLUSION--This study demonstrates a high prevalence of sexually transmitted pathogens in women with and without CIN as well as family planning clinic attenders. Bacterial vaginosis was a significant finding in women with CIN. C. trachomatis was detected in a high proportion of all women studied and found more commonly than N. gonorrhoeae. We therefore recommend that all women attending gynaecological services in a developing community be investigated and treated for sexually transmitted diseases. 相似文献

OBJECTIVE: To determine the prevalence of genital Chlamydia trachomatis infection and risk factors in women attending family planning, gynaecology, and sexually transmitted disease (STD) clinics in Jamaica. METHODS: Endocervical specimens from 645 women including 238 family planning, 170 gynaecology, and 237 STD clinic attendees were examined for C trachomatis using a direct fluorescence assay (DFA) and culture. Investigations were carried out for the presence of other STD pathogens and demographic, behavioural, historical, and clinical data recorded for each participant. RESULTS: The prevalence of C trachomatis infection was 35%, 47%, and 55% in family planning, gynaecology, and STD clinic clients, respectively. The performance of the DFA was comparable to that of culture in screening for C trachomatis. Logistic regression analysis revealed that the independent risk factors for C trachomatis infection were non-barrier contraceptive methods in family planning clients (OR = 2.1; 95% confidence interval (CI) = 1.2-3.9; p = 0.0110), cervical ectopy in gynaecology clients (OR = 3.9; 95% CI = 1.4-10.6; p = 0.0076) and concomitant Trichomonas vaginalis infection in STD clients (OR = 3.5; 95% CI = 1.8-6.8; p = 0.003). Age, number of sex partners, and reason for visit were not identified as risk factors for C trachomatis infection. CONCLUSIONS: Consistently high prevalence of C trachomatis infection occurs in Jamaican women. Universal screening or presumptive treatment should be evaluated as prevention and control measures for C trachomatis infection in this population where all women appear to be at risk. 相似文献

Prevalence of sexually transmitted diseases (STD) and selected behavioral and demographic variables were evaluated in 279 women attending a Baltimore STD clinic, using a standardized questionnaire and cultures for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis. Stratified by reason for clinic visit, 102 (37%) of 279 women attending the clinic stated that they were recent contacts to men with STDs with the majority (59 out of 102, or 58%) reporting gonorrhea contact as their reason for visit. Another 124 women (44%) came to the clinic for symptom evaluation, and 53 (19%) for other reasons. Prevalence of STDs was higher among those attending as contacts than among noncontacts: 35% versus 15% for N. gonorrhoeae; 26% versus 16% for C. trachomatis; and 27% versus 15% for T. vaginalis (P less than 0.05 for each). Furthermore, multiple infections were found in 23% of those attending as contacts but only in 10% of noncontacts (P less than 0.001). In general, patients reporting contact with an infected person were also less likely to report symptoms (43% versus 34%, P less than 0.001), despite increased disease prevalence. These data suggest that multiple STDs are often present in women attending STD clinics, irrespective of reason for visit. Merely treating women for reported exposure without further evaluation will fail to identify a substantial number of women coinfected with other organisms. 相似文献

BACKGROUND: Rates of bacterial sexually transmitted infections (STIs) continue to rise among men who have sex with men (MSM) in the UK. OBJECTIVE: To evaluate factors associated with Chlamydia trachomatis and Neisseria gonorrhoeae among MSM attending a genitourinary medicine clinic in inner London. STUDY DESIGN: 599 MSM undergoing testing for STIs were recruited. Specimens for ligase chain reaction (LCR), strand displacement amplification (SDA) assay and culture were collected from the pharynx, urethra and rectum for the detection of C trachomatis and N gonorrhoeae. Details regarding demographics, symptoms, signs and sexual behaviour were recorded. Associations of these factors with each infection were tested, adjusting for other risk factors. RESULTS: The prevalence of C trachomatis and N gonorrhoeae was 11.0% and 16.0%, respectively. LCR and SDA performed well for the detection of C trachomatis and N gonorrhoeae from urethra and rectum. Using either method, compared with our current testing policy, over 18% of those with C trachomatis and N gonorrhoeae would not have had their infection diagnosed or treated. Age, sexual behaviour, urethral and rectal symptoms and signs were strongly associated with both infections. A total of 33.7% of men reported at least one episode of unprotected anal intercourse in the previous month. Men reporting multiple episodes were markedly more likely to be HIV positive. CONCLUSION: The prevalence of infection, rates of partner acquisition and unprotected anal intercourse reported among these MSM are alarming. Improved detection of C trachomatis and N gonorrhoeae using nucleic acid amplification tests has major public health implications for STI and possibly HIV transmission in this population. 相似文献

OBJECTIVES: To examine demographic and behavioral characteristics in incarcerated women to determine which characteristics are associated with prevalent sexually transmitted infections (STIs). STUDY DESIGN: A cross-sectional analysis of data of 205 women entering jail in Rhode Island was performed as part of a study evaluating a family planning program. Women were recruited near time of commitment, and inclusion was limited to women at risk for an unplanned pregnancy. Incarcerated women were interviewed by a research assistant for demographic information, psychosocial and behavioral characteristics. Self-collected vaginal swabs were tested for STIs, including Neisseria gonorrhoeae and Chlamydia trachomatis by polymerase chain reaction and Trichomonas vaginalis by InPouch culture. Relative risks (RRs) were estimated using Poisson regression. RESULTS: Sixty-eight of 205 patients tested positive for an STI [33%; 95% confidence interval (CI) 27-40%]. Forty-five patients (26%) tested positive for T. vaginalis, 27 (14%) were positive for C. trachomatis, and 21 (11%) were positive for N. gonorrhoeae. On bivariate analysis, 6 or more sexual partners in the last year (RR 1.84; 95% CI 1.01-3.36), exchanging sex for drugs/money (RR 1.65; 95% CI 1.01-2.69), and homelessness (RR 1.82; 95% CI 1.07-3.09) were associated with STI. After adjustment for age, race/ethnicity, education, and other covariates, none of the factors was significantly associated with STI. CONCLUSIONS: The prevalence of STI in this jail population is high. Incarceration represents a unique opportunity to evaluate and treat this underserved population. Predictors of infection are limited and infection is common; therefore, routine screening should be considered in this population. 相似文献

OBJECTIVE: To estimate more accurately the age specific prevalence of Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, and human papillomavirus infection (HPV) in indigenous women living in urban, rural, and remote areas of the "Top End" of the Northern Territory (NT). DESIGN: Analysis of data obtained from two community based studies using self administered tampon specimens tested by polymerase chain reaction for sexually transmitted disease (STD). Data pertaining to the notifiable STDs (N gonorrhoeae and C trachomatis) were obtained from the NT health department. PATIENTS: 1090 indigenous women (age range 12-73 years) were enrolled when they attended local community health centres, family planning clinics, and STD clinics. The majority attended clinics in their home community in the course of "well women's checks" which encourage women to undergo screening for a variety of general medical conditions. RESULTS: The overall prevalence of T vaginalis, C trachomatis, N gonorrhoeae, and HPV was 0.25 (95% CI: 0.22-0.28), 0.11 (0.09-0.13), 0.17 (0.15-0.19), and 0.42 (0.37-0.48) respectively. Of the women found to be infected (excluding HPV), 25.5% had two or more of the above organisms detected. There was a statistically significant increase in the age specific prevalence of T vaginalis but a significant decrease with age for C trachomatis and HPV infection. There was no statistically significant change for N gonorrhoeae with age. CONCLUSIONS: STDs are hyperendemic in this population of indigenous women and the notification data significantly underestimate their prevalence. Distinct patterns of age specific prevalence were demonstrated, highlighting the need to tailor control strategies to specific epidemiological features. 相似文献

OBJECTIVE: To determine prevalences and predictors of sexually transmitted and reproductive tract infections among men and women seeking care at pharmacies. METHODS: Men and women with urethral discharge or dysuria and vaginal discharge were enrolled at 12 central and 52 smaller pharmacies in Lima, Peru. All participants answered a questionnaire. Men provided urine for polymerase chain reaction (PCR) testing for Neisseria gonorrhoeae and Chlamydia trachomatis, and for leucocyte esterase testing. Women provided self-obtained vaginal swabs for PCR testing for N gonorrhoeae and C trachomatis, Trichomonas vaginalis culture and bacterial vaginosis and Candida. RESULTS: Among 106 symptomatic men, N gonorrhoeae and C trachomatis were detected in 34% and were associated with urethral discharge compared with dysuria only (odds ratio (OR) 4.3, p = 0.003), positive urine leucocyte esterase testing (OR 7.4, p = 0.009), less education (OR 5.5, p = 0.03), and with symptoms for <5 days (OR 2.5, p = 0.03). Among 121 symptomatic women, 39% had bacterial vaginosis or T vaginalis, and 7.7% had candidiasis. N gonorrhoeae and C trachomatis were detected in 12.4% of the women. Overall, 48.8% had one or more of these infections. No factors were associated with vaginal infection, and only symptoms of vaginal discharge for <5 days were associated with N gonorrhoeae and C trachomatis (OR 4.0, p = 0.02). The main reason reported for seeking advice at pharmacies by both men and women was trust in pharmacy workers. CONCLUSIONS: Among men and women presenting to pharmacies with urethral and vaginal symptoms, rates of urethral and vaginal infections were comparable to those found in other clinical settings. Pharmacies can contribute to the care and prevention of sexually transmitted infection in developing countries. 相似文献

OBJECTIVES: To examine the performance of the syndromic approach in the management of vaginal discharge among women attending a reproductive health clinic in New Delhi, India. METHODS: Women who sought services from the clinic and who had a complaint of vaginal discharge were interviewed, underwent a pelvic examination, and provided samples for laboratory investigations of bacterial vaginosis, candidiasis, syphilis, trichomoniasis, and Chlamydia trachomatis and Neisseria gonorrhoeae infections. Data analysis focused on the prevalence of infection and on the performance of the algorithm recommended by the national authorities for the management of vaginal discharge. RESULTS: The most common infection among 319 women was bacterial vaginosis (26%). At least one sexually transmitted infection was detected in 21.9% of women. The prevalence of C trachomatis infection was 12.2%; trichomoniasis 10%; syphilis 2.2%; N gonorrhoeae was not isolated. An algorithm based on risk assessment and speculum assisted clinical evaluation was not helpful in predicting cervical infections associated with C trachomatis (sensitivity 5% and PPV 9%). This algorithm was sensitive (95%) though not specific (22%) in selecting women for metronidazole therapy effective against bacterial vaginosis or trichomoniasis, and overtreatment was a problem (PPV 38%). The sensitivity, specificity, and PPV of this algorithm for the treatment of candidiasis were 46%, 98%, and 88% respectively. The cost per case assessed using the algorithm was $2 and the cost per infection correctly treated was $4.25. CONCLUSIONS: The prevalence of cervical infection associated with C trachomatis was high among these "low risk" women. The syndromic approach is not an efficient tool for detecting this condition, and alternative approaches to evaluation and intervention are required. The syndromic management of vaginal discharge among women seeking family planning and other reproductive health services should focus on vaginal infections, thus enhancing quality of care and addressing women's concerns about their health. 相似文献

OBJECTIVE AND GOAL: The goal of this study was to study the prevalence of sexually transmitted infections (STIs)/reproductive tract infections (RTIs) among brothel-based sex workers (SWs) in Bangladesh. STUDY: A cross-sectional study was conducted among SWs in 4 randomly selected brothels. A sociodemographic and behavioral survey and pelvic examination was conducted. Specimens including endocervical swab, high vaginal swab, and blood were collected and were examined for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, bacterial vaginosis candidiasis, and syphilis. RESULTS: A total of 439 SWs were enrolled and 49.6% had genital symptoms. Among all SWs, 17.5% were positive for N. gonorrhoeae; 15.5% for C. trachomatis; 7.5% for T. vaginalis, and 6.6% had active syphilis. A total of 67.4% SWs were positive for at least 1 cervical and/or vaginal infection. CONCLUSION: The prevalence of STIs/RTIs among SWs in brothels in Bangladesh is high. An intervention strategy addressing both symptomatic and asymptomatic infections and periodic screening of SWs for RTIs/STIs is essential for successful HIV and STIs prevention programs. 相似文献

OBJECTIVE: To determine the prevalence of asymptomatic and unrecognised genital tract infections among women attending a family planning clinic in rural South Africa. METHODS: 189 consecutive women had genital samples taken to diagnose infection with Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Candida albicans, Treponema pallidum, and HIV, and to diagnose bacterial vaginosis. RESULTS: Mean age was 25 years; 155 (82%) were unmarried, 156 (83%) were currently using contraception, and 41 (22%) reported having an STD treated in the preceding 12 months. Although none volunteered abnormal urogenital symptoms, 74 (39%) had at least one elicited by direct questioning. 119 women (63%) had at least one genital infection: N gonorrhoeae (eight; 4%), C trachomatis (14; 8%), T vaginalis (26; 14%), C albicans (56; 30%), active syphilis (15; 8%), HIV (44; 24%), and bacterial vaginosis (29; 15%). 49 women (26%) had multiple infections. Most infections (71; 60%) were asymptomatic. Symptomatic women failed to recognise and report their symptoms, and routine services failed to detect the infections. CONCLUSION: Prevalence of genital tract infection is high among these women, most infections are asymptomatic, and symptomatic infections are frequently not recognised. Women attending family planning clinics in such settings should be screened for syphilis and offered testing for HIV infection. Strategies to detect and treat other genital infections need to be developed. 相似文献

BACKGROUND: In a previous community-based study among rural women in the Eastern Highlands Province (EHP) of Papua New Guinea we determined that the prevalences of Trichomonas vaginalis infection, Chlamydia trachomatis infection, and syphilis were 46%, 26%, and 4%, respectively. Surprisingly, however, the prevalence of Neisseria gonorrhoeae infection was only 1%, which we considered low in consideration of the high prevalence of other sexually transmitted diseases (STDs). The aim of the current study was to reexamine samples that were collected in that survey and retest them with use of polymerase chain reaction (PCR). STUDY DESIGN: Using a cluster-sampling method, we surveyed 201 women aged 15 to 45 years in a population of approximately 19,000 people. In addition, 243 other women living in the same area who wished to be screened for STDs were included in the study. METHODS: Endocervical samples that were stored frozen at -80 degrees C were retested with multiplex PCR (M-PCR) for the detection of both N gonorrhoeae and C trachomatis and with a separate PCR for the detection of T vaginalis. RESULTS: A total of 373 samples that were still available were analyzed. The prevalences of T vaginalis, C trachomatis, and N gonorrhoeae infections were 42.6%, 26.5%, and 18.2%, respectively; 59.8% of the women had at least one STD, while 21.7% had mixed infections, 5.9% of them with all three pathogens. CONCLUSIONS: STDs are very common among rural women in the EHP of Papua New Guinea and often present as multiple infections. 相似文献

During a 2-year period ending in October, 1989, 110 women who claimed to have been raped were treated at the sexually transmitted disease clinic at Birmingham General Hospital. A total of 22 sexually transmitted infections were found in 14 (13%) women, of which Chlamydia trachomatis (in 8%) and Trichomonas vaginalis (in 6%) were the most frequently found pathogens. In none of these patients was it possible to determine whether infection resulted from rape or from voluntary intercourse with another person. The high prevalence of infection found in this study and in previous studies indicates that all women alleging rape should be investigated at a sexually transmitted disease clinic. 相似文献

OBJECTIVES: Ligase chain reaction (LCR) technology has dramatically increased the sensitivity of tests for sexually transmitted infections (STIs). It is unknown whether low copy infections (LCR positive, culture negative) have any clinical consequences. We assessed the clinical significance of untreated low copy Chlamydia trachomatis and Neisseria gonorrhoeae infections in a cohort of sexually active women. METHODS: We studied a cohort of sexually active women followed at 6 month intervals for up to 3 years. Frozen urine specimens from 181 women with negative cultures for C. trachomatis and N. gonorrhoeae who were 'high risk' (defined as being less than 40 years old at baseline, and having either Trichomonas vaginalis at baseline or a history of more than one sexual partner during the 12 months before baseline) were tested for C. trachomatis and N. gonorrhoeae by LCR (Abbott Laboratories, Abbott Park, IL, USA). The specimens from all visits for each person were pooled and LCR was performed on the pool. Laboratory results were linked to clinical information. We also tested all urine samples obtained from patients with a positive culture. RESULTS: 10 additional infections (nine C. trachomatis and one N. gonorrhoeae) were detected with LCR technique. None of the women with low copy infection had evidence of subsequent pelvic inflammatory disease or ectopic pregnancy. Pooling of urine samples resulted in a 47% decline in the number of tests performed. CONCLUSIONS: Additional STIs can be identified when using LCR. Pooling of urine specimens is a cost saving technique for C. trachomatis and N. gonorrhoeae testing. 相似文献

OBJECTIVES: To measure the prevalence of urethral infections including trichomoniasis in rural Tanzanian men, to assess the prevalence of symptoms and signs among men with Trichomonas vaginalis, and to analyse the risk factors for trichomoniasis. DESIGN: A cross sectional study of 1004 men aged 15-54 years in a rural community in north west Tanzania. METHODS: Participants were interviewed about sexual behaviour and symptoms of sexually transmitted diseases. First fraction urine samples and urethral swabs were collected and used to test for T vaginalis by wet preparation and culture, Neisseria gonorrhoeae by culture, Chlamydia trachomatis by ligase chain reaction and non-specific urethritis by Gram stain. Urine was also tested for the presence of leucocytes using a leucocyte esterase dipstick. Men were re-interviewed 2 weeks later to document new symptoms and signs of urethritis. RESULTS: Complete laboratory results were available on 980 men. One in four men had laboratory evidence of urethritis. T vaginalis was found in 109 individuals (11%), gonorrhoea in eight (0.8%), and chlamydial infection in 15 (1.5%). Over 50% of men with urethritis were asymptomatic. The prevalence of signs and symptoms was similar among men with T vaginalis alone compared with men with other urethral infections. The sensitivity and specificity of the leucocyte esterase dipstick (LED) test for detecting T vaginalis were 80% and 48% respectively in symptomatic men and 60% and 68% in asymptomatic men. Factors associated with trichomoniasis included religion, type of employment, and marital status. CONCLUSIONS: A high prevalence of urethritis was found in men in this community based study. More than half of the urethral infections detected were asymptomatic. The most prevalent pathogen was T vaginalis. Studies are needed on the prevalence of trichomoniasis in men presenting to health services with complaints suggestive of urethritis since treatment for T vaginalis is not included in the syndromic management of urethritis in most countries. The performance of the LED test as a screening test for trichomoniasis was unsatisfactory in both symptomatic and asymptomatic men. Improved screening tests are urgently needed to identify urethral infections that are asymptomatic and which are not covered by current syndromic management algorithms. 相似文献

One thousand eight non-pregnant women aged 16-34 years, presenting for the first time at a clinic for sexually transmitted diseases (STD), were examined and screened for infection with Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and Candida species. The respective prevalence rates were 21.1%, 20.7%, 13.4%, and 27.8%. Isolation rates for C trachomatis, either occurring alone or in association with other genital infections, were significantly greater in women using oral contraceptive agents. This was not because oral contraceptive users were more promiscuous. The findings strengthen the case for providing a routine chlamydial culture service for women attending STD clinics. They also indicate that the likelihood of chlamydial infection in women taking oral contraceptives is increased. 相似文献

BACKGROUND: Clients of commercial sex workers are considered at high risk for the acquisition and transmission of sexually transmitted diseases (STDs). Identification and treatment of infections in this group could help to reduce the transmission of STDs. GOAL: To ascertain the prevalence of sexually transmitted organisms in male clients of female sex workers in Thailand by analysis of seminal fluid collected after intercourse. STUDY DESIGN: Used condoms were collected from 291 male clients attending a brothel in Hat Yai, Thailand during a 7-day period. Nucleic acid was extracted from seminal fluid and tested by polymerase chain reaction for the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, herpes simplex virus (HSV) and HIV sequences. RESULTS: Overall, 17 (6%), 47 (16%), and 2 (1%) of specimens were positive for C trachomatis, N gonorrhoeae and T vaginalis respectively. HSV sequences were found in 24 (8%) of the specimens: 14 specimens (5%) with HSV type 1, and 11 specimens (4%) with HSV type 2. HIV RNA was detected in two samples (1%). Overall, 75 specimens (26%) were positive for one or more infections, and more than one pathogen was detected in 16 specimens (5%). CONCLUSION: This study reports a high rate of STDs among clients of female sex workers in Thailand. Consequently, this population is a significant risk for transmitting STDs to commercial sex workers and to other noncommercial partners. Strategies that target this population of men are needed to reduce STD and HIV transmission. 相似文献

Two hundred and ten adolescent girls in residential care with an age range of 12 to 16 years were screened for sexually transmitted infections.
