OBJECTIVES: To review studies of sexually transmitted infection (STI) prevalence in South Africa between 1985 and 2003 in selected sentinel populations. To examine how STI prevalence varies between populations and to identify the limitations of the existing data. METHODS: Studies of the prevalence of syphilis, chancroid, granuloma inguinale, lymphogranuloma venereum, gonorrhoea, chlamydia, trichomoniasis, bacterial vaginosis, candidiasis, and herpes simplex virus type 2 (HSV-2) were considered. Results were included if they related to women attending antenatal clinics or family planning clinics, commercial sex workers, individuals in the general population (household surveys), patients with STIs, patients with genital ulcer disease (GUD), or men with urethritis. RESULTS: High STI prevalence rates have been measured, particularly in the case of HSV-2, trichomoniasis, bacterial vaginosis and candidiasis. The aetiological profile of GUD appears to be changing, with more GUD caused by HSV-2 and less caused by chancroid. The prevalence of gonorrhoea and syphilis is highest in "high risk" groups such as sex workers and attenders of STI clinics, but chlamydia and trichomoniasis prevalence levels are not significantly higher in these groups than in women attending antenatal clinics. CONCLUSIONS: The prevalence of STIs in South Africa is high, although there is extensive variability between regions. There is a need for STI prevalence data that are more nationally representative and that can be used to monitor prevalence trends more reliably. 相似文献

OBJECTIVES: To determine baseline prevalence of sexually transmitted infections (STI) and other reproductive tract infections (RTI) and their association with HIV as well as sociodemographic and behavioural characteristics in a newly recruited cohort of female bar workers in Mbeya Region, Tanzania. METHODS: 600 female bar workers were recruited from 17 different communities during September to November 2000 and underwent gynaecological examination, laboratory testing for HIV/STI, and interviews using structured questionnaires. RESULTS: HIV-1 seroprevalence was 68%. Prevalences of STI/RTI were high titre syphilis (TPPA/RPR >/=1/8), 9%; herpes simplex virus 2 antibodies, 87%; chlamydia, 12%; gonorrhoea, 22%; trichomoniasis, 24%; and bacterial vaginosis, 40%. HIV infection was associated with TPPA and HSV-2 seropositivity, bacterial vaginosis and clinically diagnosed genital ulcers, blisters, and warts. Reported high risk sexual behaviour during the past year (having multiple casual partners) was associated with prevalent STI. CONCLUSION: Female bar workers in Mbeya are at high risk of STI and HIV infection. Targeted STI/HIV prevention interventions for these women and their sexual partners need to be reinforced. Methods should be sought to improve healthcare seeking and to provide easily accessible and affordable STI care services. 相似文献

OBJECTIVE: To determine the aetiology of genital ulcers and discharges in rural south western Uganda and to assess response to syndromic treatment. METHOD: A longitudinal, prospective study using laboratory testing and questionnaires to evaluate 561 adult men and women presenting with clinically verified genital ulcers, urethral, or vaginal discharge at a general outpatient clinic and two health centres between December 1999 and July 2001. RESULTS: One third of patients had genital ulcers and two thirds discharges. There was good response to treatment in 461/508 patients (90.7%). Herpes simplex virus type 2 was found in 95/217 (43.8%) genital ulcers. In 24.1% of ulcer cases there was also a genital discharge. HIV seropositivity was high in ulcer cases (63.2%), with significantly more HSV2 and secondary bacterial infection than in seronegative cases. Neisseria gonorrhoeae was found in 135/204 (66.2%) male genital discharges. Female genital discharges were mostly associated with bacterial vaginosis (36.1%), Trichomonas vaginalis (18.9%), and candidiasis (18.6%). CONCLUSIONS: The aetiological pattern of STI syndromes reported will help inform revision of national STI guidelines. The importance of herpes simplex virus type 2, the variation in causes of genital ulcers according to HIV serostatus, the high frequency of multiple infections and secondary bacterial contamination of genital ulcers are notable. These results help explain the lack of effect of an STI intervention on HIV incidence in a recent trial in this area. 相似文献

OBJECTIVES: To investigate the prevalence and risk factors of HSV-1 and HSV-2 antibodies in HIV infected women and the association between recurrent genital ulcerations and HIV disease progression in HSV-2 positive women. METHODS: The presence of HSV antibodies was tested in 276 of the 487 women participating in a European cohort study of HIV infected women. Prevalence rate ratios described the association between HSV infection and its risk factors, using log binomial regression. Generalised estimating equations (GEE) analysis was performed to determine the impact of markers of HIV disease progression on recurrent genital ulcerations. RESULTS: The prevalence of HSV-1 and HSV-2 antibodies was 76% (95% confidence interval (95% CI): 71-81) and 42% (95% CI: 36-50); 30% (95% CI: 24-35) of the women had antibodies against both HSV-1 and HSV-2. The prevalence of HSV-1 was 86% (95% CI: 80-92) in southern Europe compared with 69% (95% CI: 57-79) and 67% (95% CI: 55-77) in central and northern Europe (p=0.002). This geographical variation remained after adjustment for other risk factors. An increasing number of years of sexual activity (p=0.0002) and a history of prostitution (p=0.0001) were independently associated with HSV-2 prevalence. In HSV-2 positive women, symptomatic cases of HSV infection were minimal, but increased with decreasing CD4 count. CONCLUSION: In HIV infected women, the prevalence of HSV antibodies is high and symptomatic cases of HSV infection are minimal, but increase with decreasing CD4 count. HSV-2 but not HSV-1 was related to sexual behaviour (that is, a history of prostitution and the number of sexually active years) in this group of HIV infected women. 相似文献

BACKGROUND: Herpes simplex virus (HSV) infections are among the most common infectious diseases in humans. The prevalence of herpes simplex viruses type 1 (HSV-1) and type 2 (HSV-2) varies widely across the world. HSV-2 infection is the primary cause of genital herpes. It is highly prevalent in human populations in many parts of the world, and is the most common cause of genital ulcer disease worldwide. In spite of the large prevalence and growing incidence of herpes simplex infection (HSV-1 and HSV-2), relatively few data have been published regarding the seroprevalence of herpes simplex infection, while no data exist regarding the Turkish population. METHODS: We aimed to investigate the prevalence of HSV-1 and HSV-2 in selected populations in Turkey. A cross-sectional study was conducted involving 2082 serum samples of 725 adults, 300 pregnant women, 200 blood donors, 483 sex workers and 110 patients with genital warts and 264 hotel staff in Istanbul, Turkey. All serum samples were assessed for HSV1 and HSV-2 IgG antibodies using an HSV-type specific, enzyme-linked immunosorbent assay (ELISA). RESULTS: The prevalence of HSV-2 and HSV-1 antibodies was 4.8 and 85.3% in sexually active adults; 5.5 and 96% in blood donors; 5 and 98% in pregnant women, 17.3 and 93.6% in patients with genital warts; 8.3 and 97.3% in hotel staff; and 60% and 99% in sex workers. CONCLUSION: These results confirm a higher prevalence of HSV infection than estimated, especially in high risk groups in Turkey. The high prevalence of HSV infection underlines the need for education among these populations. 相似文献

BACKGROUND: Studies demonstrating previous herpes simplex virus (HSV) type 2 infection as a risk factor for HIV transmission, and the development of a HSV vaccine candidate, have emphasised the need for worldwide population based studies of HSV seroprevalence. The only nationwide seroprevalence studies have been conducted in the United States. METHODS: An Australia-wide, population based study of HSV-1 and HSV-2 seroprevalence was conducted, using serum and sociodemographic data collected between 1999-2000, for a representative study of risk factors for diabetes in over 11 000 adults. A stratified random sample of 4000 was tested for HSV-2 and 1000 for HSV-1, with sampling and weighting for various demographic factors. RESULTS: Seroprevalence of HSV-2 in Australian adults was 12%. Prevalence in women (16%) was twice that in men (8%). Rural populations had a lower prevalence (9%) than metropolitan (13%), and Indigenous had a higher prevalence (18%) than the non-Indigenous populations (12%). The seroprevalence of HSV-1 was 76% with significant differences by age group, sex and Indigenous status. CONCLUSION: These are the first nationwide data to compare with US studies. HSV-2 infection is less common in Australia than the United States, and this will allow planning for combating HIV transmission in high prevalence populations in northern Australia. In addition, the high HSV-1 seroprevalence will be important for future deployment of genital herpes vaccines. 相似文献

Increasing proportion of herpes simplex virus type 1 as a cause of genital herpes infection in college students 总被引:8,自引:0,他引:8
A retrospective review of genital herpes simplex virus (HSV) isolates collected in a university student health service over a 9-year period showed that an increasing proportion of isolates were HSV-1 rather than HSV-2. HSV-1 accounted for 78% of all genital isolates in this population by 2001, compared with 31% of isolates in 1993. BACKGROUND: Herpes simplex virus (HSV) type 1 is usually thought to cause less than 30% of genital herpes infections in the United States, but the proportion of infections resulting from HSV-1 is increasing in some populations. GOAL: The goal was to review the relative proportion of HSV-1 and HSV-2 as the cause of newly diagnosed genital herpes infections in a population of U.S. college students and to assess trends in the change of this proportion over time. STUDY DESIGN: Genital HSV isolates collected at a university student health service from 1993 to 2001 (n = 499) were reviewed retrospectively. Analyses included comparisons of isolates by HSV type, age group, and sex. RESULTS: The proportion of newly diagnosed genital herpes infections resulting from HSV-1 increased from 31% in 1993 to 78% in 2001 (P <0.001, linear trend P <0.001). HSV-1 was more common in females than males, but increases were noted for both sexes. HSV-1 was more common in persons aged 16 to 21 than in persons aged 22 or older. CONCLUSIONS: HSV-1 has become the most common cause of newly diagnosed genital herpes infections in this population of college students and reflects a reversal of the usual HSV-1/HSV-2 ratio. 相似文献

OBJECTIVES: To determine the proportion of herpes simplex virus type 1 (HSV-1) and HSV type 2 (HSV-2) in first episodes of genital herpes. To evaluate the use of HSV specific serology for classifying first episodes of genital herpes and for defining HSV serostatus in the patients' sexual partners. METHODS: 108 consecutive patients with first episodes of genital herpes seen at three STD clinics in Sweden from 1995 to 1999 were included in the study. HSV culture and typing were performed and serum was tested for antibodies against a type common HSV antigen and a type specific HSV-2 antigen, glycoprotein G2 (gG2). A structured interview including questions about sexual behaviour and sexual partners was taken. "Steady" partners were offered a blood test for HSV serology and counselling. RESULTS: Of 108 patients, 11 had a negative HSV culture. Of the 97 who were HSV culture positive, 44% (43/97) were typed as HSV-1 and 56% (54/97) as HSV-2. For 86 of these 97 patients, HSV serology from the initial visit was available. Of 52 primary infections, thus initially seronegative, 64% were HSV-1 infections and of 19 female primary infections 16 (84%) were HSV-1. In 17% the first episode of genital herpes corresponded to the first clinical recurrence of an infection acquired earlier in life. There was a significant correlation between having orogenital sex and being infected with HSV-1 and also a history of labial herpes in the partner. Only 20% of partners of patients with an HSV-2 infection had a history of genital herpes. CONCLUSIONS: Almost half of first episodes of genital herpes are caused by HSV-1. In young women with a primary genital infection, HSV-1 is much more frequent than HSV-2. Besides HSV typing, we found specific HSV serology of value for classifying first episodes and for diagnosing a subclinical HSV-2 infection in partners. Anamnestic data supported the suggestion that the orogenital route of transmission was common in genital HSV-1 infections. 相似文献

GOAL: The goal of this study was to investigate the trends in the prevalence of anogenital herpes caused by herpes simplex virus (HSV) type-1 and HSV-2 among patients attending a sexually transmitted infections clinic. METHODS: We conducted a retrospective study of virologically proven first-episode genital herpes diagnosed in the Department of Genitourinary Medicine in Edinburgh between 1989 and 2002. RESULTS: First-episode anogenital herpes was associated with HSV-1 in 659 (62%) women and 294 (42%) men (P <0.0002). HSV-1 was recovered more often from women younger than 25 years than from older women (P <0.0005). For both HSV-1 and HSV-2 infections, the median ages of heterosexual men (26.0 and 28.0 years, respectively) were significantly higher than those of women (23.0 and 25.0 years, respectively)(P <0.05). The median age of men who have sex with men with HSV-1 (29.0 years) was significantly higher than that of heterosexual men (26.0 years)(P <0.01). CONCLUSION: HSV-1 remains the most common cause of symptomatic first-episode anogenital herpes, especially among young women in our clinic population. 相似文献

BACKGROUND AND OBJECTIVES: Sexual transmission of bacterial and viral sexually transmitted disease has been reported between women. No data are available on seroprevalence of herpes simplex virus type-1 (HSV-1) and type-2 (HSV-2) among lesbians. GOAL: The goal was to define prevalence of infection with HSV-1 and HSV-2 among lesbians, and associated risk factors. STUDY DESIGN: Women who reported sex with another woman in the preceding year were eligible. Medical and sexual histories were obtained. Serum was tested for HSV-1 and HSV-2 antibodies using Western Blot assay. RESULTS: Among 392 subjects, antibodies to HSV-1 were detected in 46% and to HSV-2 in 8%. Increasing age predicted higher seroprevalence to both HSV types, and HSV-2 seropositivity was associated with a history of male partner with genital herpes. Of 78 women reporting no prior sex with men, 3% were HSV-2-seropositive. Most HSV-2-seropositive subjects (71%) reported no history of genital herpes. HSV-1 seroprevalence increased significantly with an increasing number of female sex partners. CONCLUSIONS: HSV-2 infection occurs in nearly 1 in 10 lesbians and is not predicted by report of sex with men or sexual identity. Most lesbians infected with HSV-2 are not aware of their infection. Sexual transmission of HSV-1 may occur more frequently among lesbians than among heterosexual women. 相似文献

Introduction and objectiveThe epidemiology of genital herpes has changed in recent years with an increase in the incidence of herpes simplex virus type 1 (HSV-1) infection. The aim of this study was to analyze the clinical and epidemiological characteristics of patients diagnosed with genital herpes.Material and methodsA retrospective observational study was designed. All patients diagnosed with genital herpes between January 2016 and January 2019 in a Sexually Transmitted Infections Unit (ITS) in Valencia, Spain, were included.ResultsWe identified 895 STI diagnoses. Of these, 126 (14%) were genital herpes; 68 (54%) of these cases were in women and 58 (46%) in men. Diagnosis was confirmed by molecular detection of HSV DNA in 110 cases (87.3%). Of these, 52 were cases of HSV-1 infection (47.3%) and 58 were HSV-2 infection (52.7%). HSV-2 was more common in men (69.5%), while HSV-1 was more common in women (59.3%). In the subgroup of women, mean age at diagnosis was 26 years for HSV-1 and 34 years for HSV-2 (P = .015). Recurrent genital herpes rates were 13% for HSV-1 and 40% for HSV-2.ConclusionsThere has been an increase in the number of cases of genital herpes caused by HSV-1 in our setting, with young women in particular being affected. This has important prognostic implications because genital herpes caused by HSV-1 is less likely to recur. 相似文献

BACKGROUND: Genital herpes is one of the most common sexually transmitted diseases. As a leading cause of genital ulceration, herpes genitalis plays a role in facilitating the transmission of HIV. Although HIV infection is most prevalent in Cameroon, information is lacking about prevalence of herpes simplex virus (HSV) type 2 infection in this country. GOAL: The goal was to determine the prevalence of HSV-2-specific antibody in blood specimens from individuals in Cameroon. STUDY DESIGN: Blood specimens were randomly collected from 410 clinic attendees (215 males, 195 females) in Douala, the most populous city in Cameroon. One hundred fifteen of the individuals (28.0%) were HIV-infected. Samples were tested by a type-common HSV IgG enzyme immunoassay not discriminating between HSV-1 and HSV-2 antibodies and by two glycoprotein G-2-based enzyme immunoassays for detection of HSV-2-specific antibody. RESULTS: All but three blood samples were positive for type-common HSV IgG antibodies. Sixty-seven specimens (16.3%) were concordantly negative for HSV-2 antibody by both assays, and 287 (70.0%) specimens were concordantly positive. Fifty-six specimens (13.7%) yielded discrepant results between the two assays. CONCLUSION: On the basis of specimens with concordantly positive results, the overall HSV-2 seroprevalence was 70.0%. HSV-2 seroprevalence was significantly higher among HIV-infected individuals than among HIV-negative ones. Because of the serious morbidity and mortality caused by HSV-2, effective programs are needed to halt the spread of HSV-2 infection in Cameroon. 相似文献

Herpes simplex virus type 1 is the prevailing cause of genital herpes in the Tel Aviv area, Israel 总被引:1,自引:0,他引:1
BACKGROUND AND GOAL: The changing epidemiology of genital herpes with the increasing importance of herpes simplex virus (HSV) type 1 prompted a study on the relative prevalence of HSV-1 and HSV-2 among cases of genital herpes in the Tel Aviv area, Israel. STUDY DESIGN: A retrospective laboratory-based study of positive genital and nongenital herpes cultures performed at the Beilinson Medical Center between 1993 and 2002. Data regarding the number of isolates of each type and the age and sex of patients with genital lesions were retrieved from the database. Cultures were performed using Vero cells, and positive results were confirmed and typed by immunofluorescence. RESULTS: A total of 285 positive genital cultures and 659 positive nongenital cultures were recorded. HSV-1 was identified in 189 (66.3%) of the positive genital specimens and in 656 (99.55%) of the nongenital specimens. HSV-1 was isolated in 174 of 262 (66.4%) female subjects and 15 of 23 (65.2%) male subjects. The proportion of HSV-1 genital isolates was 72.7% in patients 15 to 24 years of age, 62% in those 25 to 44 years, and 46% in those aged 45 years or older. Overall, the annual isolation rate of genital HSV-1 has not changed markedly over the years. CONCLUSION: Herpes simplex virus type 1 has clearly been the predominant HSV type isolated from genital specimens in the Tel Aviv area over the last decade. 相似文献

BACKGROUND: Neonatal herpes is a condition with high morbidity and mortality. The greatest risk occurs when the mother acquires herpes simplex virus (HSV) towards the end of pregnancy. A study from Seattle has suggested that the risk of acquisition of HSV during pregnancy was 3.7%. In Australia, HSV-2 infection is less common in pregnant women than in the United States. Consequently we conducted a study to establish HSV seroprevalence and the rate of HSV seroconversion in this population. METHODS: The study was conducted at Westmead Hospital, Sydney, between June 1995 and April 1998. Women completed a questionnaire covering risk factors for the acquisition of genital herpes. A serum sample during pregnancy and a specimen of cord blood were obtained and tested for antibodies to HSV-2 using a type specific indirect enzyme linked immunosorbent assay (ELISA). Equivocal results were resolved by western blot. A subset of the paired sera was tested for antibodies to HSV-1. The data were analysed using SPSS. RESULTS: 326 of the 2616 (12.5%) women were HSV-2 seropositive. Three women (0.15%) acquired HSV-2 infection during pregnancy. None of the three babies of these mothers developed neonatal herpes. 416 maternal cord pairs were tested for HSV-1 antibodies and 330 (79.3%) were positive. No HSV-1 seroconversions occurred. CONCLUSIONS: In this population, HSV acquisition was uncommon (0.34% per year) and neonatal herpes was rare. A cost effective analysis suggested that type specific serology to screen pregnant women and their partners in low prevalence communities was not cost effective. 相似文献

OBJECTIVES: To describe the epidemiology of type specific recurrent genital herpes, and to compare the duration of recurrent genital lesions caused by herpes simplex virus (HSV) types 1 and 2. METHODS: Participants were enrolled at clinics across the United States. Adults suspected of having active genital herpes were eligible. Lesions were cultured for HSV and typed. Data from 940 participants with recurrent culture positive HSV lesions were analysed. Pearson's chi(2) and Fisher's exact tests, multivariate logistic regression models, and a stratified Cox proportional hazards model were used to compare epidemiological characteristics and lesion duration of HSV-1 and HSV-2. RESULTS: HSV-1 was present in 4.2% of the recurrent HSV culture positive lesions. HSV-1 was most prevalent among whites (6.5%) and individuals with 0-2 recurrences in the previous year (9.1%) and, among men, in those with rectal/perirectal lesions (13.2%). Longer lesion duration was not significantly associated with virus type (hazard ratio (HR) 0.95, 95% confidence interval (CI) 0.65 to 1.38, p = 0.79), but was associated with male sex (HR 0.85, 95% CI 0.74 to 0.99, p = 0.04), and HIV seropositivity (HR 0.62, 95% CI 0.48 to 0.81, p<0.01). CONCLUSIONS: The authors found that, in the United States, recurrent genital HSV-1 is relatively rare in the STD and HIV clinic setting, especially among black people. Among men, rectal/perirectal recurrent lesions are more likely to be caused by HSV-1 than are penile lesions. In addition, lesion duration depends on sex and HIV status but not virus type. These findings shed new light on the type specific epidemiology of recurrent genital HSV, and suggest that type specific testing can inform the prognosis and management of genital herpes. 相似文献

OBJECTIVES: To better understand the sexually transmitted infection (STI)/HIV dynamics in an urban west African setting in order to adapt STI/HIV control efforts accordingly. METHODS: Review of STI and HIV epidemiological studies performed over the past decade in Bobo-Dioulasso, the second city of Burkina Faso. Trends in STI prevalence among commercial sex workers and the general population were assessed over time through studies that used the same recruitment and laboratory diagnostic procedures. Variations in aetiologies of vaginal discharge, urethral discharge, and genital ulcers were also evaluated among patients consulting for genital infection complaints. Antenatal clinic based surveys provided data to assess HIV trend among the general population. RESULTS: We observed an important decline of classic bacterial STI such as syphilis, Neisseria gonorrhoea, Chlamydia trachomatis, and Haemophilus ducrey infections in all study groups. Trichomoniasis also declined but to a lesser extent. HIV infection followed the same trend at the same time, with a significant decline in the 15-19 year age group of pregnant women, suggesting a possible decrease of HIV incidence. Although no evidence of a causal relation can be drawn from this review, adoption of safer sex behaviour, introduction of the syndromic management (SM) approach, or higher antibiotic use may have contributed to these changes. CONCLUSIONS: Classic bacterial STI declined over the past decade in parallel with a stabilisation of HIV infection. Variations in syndromes aetiology and sexual behaviours should be monitored as part of STI surveillance in order to improve STI syndromic management algorithms and to adapt HIV/STI prevention efforts. 相似文献

OBJECTIVES: To document the prevalence of reproductive tract infections (RTI) and sexually transmitted infections (STI) among women attending a basic healthcare clinic in Dhaka, Bangladesh, to identify risk factors associated with the diseases and to estimate the incidence of syphilis, hepatitis C (HCV), hepatitis B (HBV), and herpes simplex type 2 (HSV-2) infection. METHODS: A cross sectional sample of 2335 consecutive women was examined during 1996-8. Women were interviewed about risk factors for RTI/STI and tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Treponema pallidum, HIV, HCV, HBV, HSV-1 and HSV-2 infection as well as vaginal candidosis and bacterial vaginosis. Women with antibodies to T pallidum were retested at regular intervals. One year after ending the study seroconversion for syphilis, HBV, HCV, and HSV-2 infection was detected among women initially negative for the respective diseases. RESULTS: The overall prevalence rate of N gonorrhoeae, C trachomatis, T vaginalis, and T pallidum infection was 0.5%, 1.9%, 2.0%, and 2.9% respectively. Overall, 35% of the women had antibodies to hepatitis B core antigen, 0.9% had HCV, and 12% HSV-2 infection. Risk factors for gonorrhoea/C trachomatis infection were a husband not living at home or suspected of being unfaithful. HSV-2 infection was associated with the same risk factors and with a polygamous marriage. The prevalence of HSV-2 infection among women "at risk" was 23%. HIV infection was not diagnosed. Repeated serological examination indicated that only 32% of women with serological evidence of syphilis had active disease. The seroincidences of HBV, HCV, and HSV-2 were 0.03, 0.007, and 0.009 per person year. Seroconversion for syphilis was not observed. 相似文献

Epidemiology of genital herpes - recent advances 总被引:3,自引:0,他引:3
Genital herpes is a common, distressing infection which, due to increasing incidence world-wide, has become a prominent public health issue over recent years, even throughout the decade of human immunodeficiency virus (HIV). Since the late 1970's, the prevalence of herpes simplex virus type 2 (HSV-2) infection has increased by approximately 30 percent in the US. The number of sufferers world-wide is currently estimated at approximately 86 million people. New serological methods based on the detection of type-specific antibodies to herpes simplex virus (HSV) glycoproteins have clarified issues concerning the true incidence of genital herpes, the modifying effect of prior HSV-1 infections, the changing proportions of HSV-1 genital herpes, and the importance of asymptomatic shedding. Patients' ignorance of their diagnosis along with the occurrence of atypical symptomatology and asymptomatic viral shedding of HSV all contribute to the transmission of genital herpes. Genital ulcer disease, of which genital herpes is the most common cause in developed countries, is an important risk factor in the acquisition and transmission of human immunodeficiency virus (HIV) infection and has contributed to the spread of this disorder. Risk factors for genital herpes HSV-2 are strongly related to lifetime number of sexual partners, number of years of sexual activity, male homosexuality, black race, female gender and a history of previous sexually transmitted diseases (STD). Understanding the epidemiology of genital herpes is of great importance in limiting the spread of this STD. In this review, we summarise current knowledge related to the epidemiology of genital herpes. 相似文献

OBJECTIVES: To measure prevalence of selected sexually transmitted infections (STI) and HIV among female sex workers (SWs) in the red light area of Surat, India, and to evaluate the performance of STI syndrome guidelines (for general population women in India) in this group against the standard aetiological diagnosis of STIs by laboratory methods. METHODS: In a cross sectional study, 124 out of an estimated total of 500 SWs were mobilised to a health camp near the red light area during 2000. After obtaining consent, a behavioural questionnaire was administered, followed by clinical examination and specimen collection for different STIs. 118 SWs completed all aspects of the survey. HIV testing was unlinked and anonymous. RESULTS: The mean number of different sexual partners of SWs per day was five. 94.9% reported consistent condom use with the clients. 58.5% of SWs had no symptoms related to STDs at the time of examination. Reported symptoms included lower abdominal pain (19.5%), abnormal vaginal discharge (12.7%), painful sexual intercourse (12.7%), painful micturition (11.0%), itching around the genital area (10.2%), and genital ulcer (5.9%). The prevalence of STI "syndromes" were vaginal discharge syndrome 51.7%, pain in lower abdomen 19.5%, enlarged inguinal lymph nodes 11.9%, and genital ulcer 5.9%. Based on the laboratory reports (excluding HIV tests), 62 (52.5%) SWs did not have any of the four tested STIs. Prevalence of laboratory confirmed STIs were syphilis 22.7% (based on reactive syphilis serology tests), gonorrhoea 16.9%, genital chlamydial infection 8.5%, and trichomoniasis 14.4%. HIV prevalence was 43.2%. The performance of Indian recommended treatment guidelines for vaginal discharge syndrome (VDS) and genital ulcer syndrome (GUS) against aetiological diagnosis was poor. CONCLUSION: Prevalence of different STIs and HIV among the FSWs in the Surat red light area is high despite high reported condom use with clients. Syndromic case management is missing a large number of asymptomatic cases and providing treatment in the absence of disease. Therefore, it is necessary to explore alternative strategies for control of STIs in female sex workers. STI services need to be improved. 相似文献

OBJECTIVES: To estimate prevalence and risk factors for herpes simplex 2 (HSV2) positivity, syphilis and Chlamydia trachomatis infection among rural people aged 15-34 in the Gambia. METHODS: Questionnaires and serum samples were collected from 1076 men and women aged 15-34 during a cross sectional prevalence survey in a rural area of the Gambia. Sera were screened for antibodies to herpes simplex virus type 2 (HSV2), and for syphilis using Treponema pallidum haemagglutination assay (TPHA) and rapid plasma reagin (RPR) tests. Urine was tested by polymerase chain reaction (PCR) for C trachomatis infection. RESULTS: 28% of women and 5% of men were HSV2 ELISA positive; 10% of women and 2% of men were TPHA positive; and 7% of women and 1% of men were both RPR and TPHA positive. Out of 1030 urine sample tested only six were positive for C trachomatis. 7% of those who reported never having sex were positive for one or other of these tests. Prevalences of all STIs increased with age and were higher in women than men. Women were much less likely than men to seek treatment for STI symptoms at a health centre. Married people were at increased risk of an STI compared with single people. Jola and Fula women had a higher prevalence of HSV2 than women from other ethnic groups, and Fulas also had a higher prevalence of RPR/TPHA positivity. The limited number of sexual behaviour questions were not significantly associated with STIs after adjustment for age, marital status, and ethnic group. CONCLUSIONS: The prevalences of the ulcerative infections HSV2 and syphilis in this population are a cause for concern. In a setting where HIV1 prevalence remains low this indicates an urgent need for STI control and behaviour change programmes to prevent an HIV epidemic. Concerns about the validity of reported sexual behaviour data high light the necessity of biological markers in the evaluation of behaviour change programmes. 相似文献
