OBJECTIVETo investigate the social factors of patients with genital herpes (GH) relapsing and guide GH patients to avoid the related social factors.

METHODSTo select 96 case of patients with recurrent genital herpes of final diagnosis and detailedly record the related social factors before relapsing. The social factors were compared between male and female GH patients, and compared between frequently recurrent (> 6/year) and non-frequently recurrent GH patients (< or = 6/year) too.

RESULTS65.6% (63/96) of recurrent GH patients have certain social factors before relapsing. The main social factors are overtiredness, mental stress and excessive sexual contact. Staying up late and excessive drinking are common social factors, too. There was no significant difference of social factors between male and female GH patients (P >. 05), and also no significant difference between frequently recurrent and non-frequently recurrent GH patients (P > 0.05), too.

CONCLUSIONOvertiredness, mental stress and excessive sexual are the main social elements during inducing genital herpes relapsing. It is important to reduce GH relapsing and spreading of HIV and syphilis by guiding recurrent genital herpes patients to avoid related social elements.

OBJECTIVETo investigate the epidemic trend and features of male genital herpes (GH) in Tianjin.

METHODSWe statistically analyzed the epidemiological data of the male GH patients received at the Venereal Disease Clinic of Tianjin Medical University General Hospital from 2006 to 2010.

RESULTSA total of 130 cases of male GH were reported from 2006 to 2010, ranging in age from 18 to 76 years, with 31.54% aged at 30-39 years. Most of the patients were factory workers (30.77%) and clerks (30.00%). Those with high school education accounted for 61.54%, and those with college education 32.31%. The sex partners of the patients were mostly waitresses (60%).

CONCLUSIONThe epidemic of GH has not been effectively controlled in Tianjin. New measures have to be developed targeting the changed epidemiological features of GH for better prevention and control of the disease.

PURPOSE: This study determined the seroprevalence of herpes virus 2 in gravidas and the differences between herpes virus 2-infected and healthy gravidas. The need to screen gravidas for herpes virus 2 was also evaluated. MATERIALS AND METHODS: A retrospective analysis involving 500 gravidas who underwent herpes virus 2 serologic testing and delivery in our hospital between January 2009 and August 2010 was performed. All patients in the study group were classified as herpes simplex virus 2 (HSV2) positive, and all cases were analyzed with respect to the clinical course of the pregnancy, pregnancy outcome, obstetric complications, and neonatal outcomes. SPSS software (version 14.0) was used for statistical analysis. A chi-square test and Student's t-test were used for statistical analysis. RESULTS: In the current study, the herpes virus 2 seroprevalence rate in gravidas was 17%. There was no significant difference in the rates of preterm delivery, premature rupture of membranes, preterm labor, and intrauterine growth restriction between the herpes virus 2-infected gravidas and the healthy control group. The rates of spontaneous abortion and sexually transmitted disease were higher in the herpes virus 2 infection group than the healthy control group. CONCLUSION: After educating gravidas on genital herpes and, if gravidas thereafter consent to herpes virus 2 screening, the risk of neonatal herpes virus 2 infections can be reduced. In addition, examination of gravidas for sexually transmitted diseases would increase as would appropriate treatment.

Changes in sexual behavior may constitute an important contribution to relative increase in genital herpes. Many research results suggest that HSV-2 plays a big part in the transmission of HIV infection. There is an urgent need to identify effective HSV-2 control measures in order to reduce HIV incidence. The detection of HSV-2-specific antibodies in serum is especially useful and reliable. During the past 2 decades, selective and specific inhibitors of replication have been developed. Such agents as acyclovir, valaciclovir and famciclovir, have reduced the time of healing and the possibility of virus excretion. Efforts have been made in different directions including the exploration of new targets for antiviral chemotherapy, the use of immunomodulators and the development of specific vaccines.

OBJECTIVETo survey the prevalence and risk factors of HSV-2 among Chinese and Vietnamese female sex workers (FSW) in the border county of Hekou, Yunnan Province, China.

METHODSA cross-sectional survey was conducted on demographics, sexual behavior, medical history, and drug use among FSWs. Laboratory samples were obtained to test for HSV-2 and other STIs such as HIV, Syphilis, Trichomonas vaginalis, Neisseria gonorrhoeae, Chlamydia trachomatis, Bacterial vaginosis, and Yeast infections. Cervicitis and genital warts were also diagnosed.

RESULTSOf the 345 FSWs who participated in this study, 112 (32.5%) were ethnic Chinese and 233 (67.5) were Vietnamese. Among FSWs in Hekou, the prevalence rates were 58.3% for HSV-2, 5.5% for HIV, and 4.1% for bacterial vaginosis (BV). Age<21 (OR: 0.5; 95% CI: 0.3, 0.8), duration of commercial sex work≤3 months (OR: 0.5; 95% CI: 0.3, 0.8), oral and vaginal sex with the last client (as opposed to only vaginal sex) (OR: 1.6; 95% CI: 1.0, 2.7), HIV (OR: 11.4; 95% CI: 1.5, 87.2), and bacterial vaginosis (BV) (OR: 5.6; 95% CI: 1.2, 26.9) were significantly correlated with HSV-2 infection.

CONCLUSIONMultivariate analysis showed that several factors were significantly correlated with the high prevalence of HSV-2 in FSWs in the border area between China and Vietnam. Further studies and interventions are needed for HSV-2 epidemiology in the border area.

OBJECTIVETo explore the epidemic characteristics of vaginal douching, human immunodeficiency virus (HIV) and other sexually transmitted diseases(STD) among female sex workers (FSWs) in Yunnan province.

METHODSFSWs were recruited to be investigated on their demographic data, drug abuse and sexual behavior, HIV/AIDS knowledge and procreation health status. Venous blood were collected to test for HIV, herpes simplex virus 2 (HSV-2) and syphilis while urine specimen was for morphine, cervical secretion for Gonorrhoea and Chlamydia trachomatis, and vaginal secretion for Trichomonas.

RESULTSA total number of 833 blood specimen were collected, in which 84 specimen were confirmed to be HIV positive with a prevalence rate of 10.1%. The prevalence rates of syphilis and HSV-2 were 8.2% and 68.4% respectively. 832 vaginal and cervical secretion specimen were collected with the prevalence rates of Gonorrhoea, Chlamydia trachomatis and Trichomonas were 11.5%, 28.2% and 11.9% respectively. In multivariate logistic analysis, the factors associated with vaginal douching were: being Han nationality, locations of sex work at middle/high level, ever heard of HIV/AIDS, emerged hypogastric pain last year, the number of sex work location > or =4.

CONCLUSIONVaginal douching was shown a risk factor for HIV and some STD.

To determine the characteristics of seroprevalence of herpes simplex virus type 2 (HSV-2) infection among Korean people, a cross-sectional study was conducted on three groups in 2004. The three groups consisted of the general public who visited public health centers, commercial sex workers (CSWs), and human immunodeficiency virus (HIV)-infected persons. Among the general public, HSV-2 seroprevalence rates for age under the 20s, in the 20s, 30s, 40s and the above 22.6%, 32.7% and 32.3%, respectively, which showed rapid increase of the rate in the 30s (p<0.0001). In case of the above of 19 yr old, women (28.0%) was higher than men (21.7%) (p<0.0001). The rate of CSWs (81.6%) was about 10 times higher than that of general women. In case of HIV-infected men (47.6%), the figure was about 2-3 times higher than that of general men. The low rate in the teens and the 20s proved that it is essential to develop sexually transmitted infections (STIs) prevention programs of education and publicity for them as a precaution measure. This study is the first major study of its kind on HSV-2 and would provide basic data for prevention of STIs including information about target groups subject to vaccination program.

Objective: This study aimed to understand the herpes simplex virus-2 (HSV-2) infection and related factors among female drug abusers in the women's compulsory drug rehabilitation center of Shandong province and to provide reference for the prevention and control of HSV-2 in these settings. Methods: We screened all of 451 female drug abusers in the women's compulsory drug rehabilitation centers in of Shandong province and conducted a study using both questionnaire investigation and serological tests for HSV-2, HIV and syphilis. We also used EpiData 3.1 software to establish a database and SPSS 20.0 software to conduct the χ(2) test and multivariate logistic regression analysis. Results: A total of 451 female drug abusers were under study. We noticed that the rates for HSV-2 infection, HIV infection and syphilis infection appeared as 72.1% (325/451), 2.2% (10/451) and 33.5% (151/451) respectively. Results from univariate analysis showed that factors as: awareness on AIDS, having temporary sex partner after using the drug, having multiple sex partners after using the drug, providing commercial services or having temporary sex practice before being detained, with syphilis infection etc., were associated with HSV-2 infection. Data from the multivariate analysis showed that the OR (95%CI) value of HSV-2 infection was 2.90 (1.19-7.06) for those who providing commercial service, when comparing to those who did not. Compared to those who did not suffer from syphilis infection, the OR (95%CI) value of HSV-2 infection for those with syphilis infection was 2.75 (1.63-4.63). Conclusions: The rate of HSV-2 infection was high in the women's compulsory drug rehabilitation center of Shandong province. We should enhance measures and promote condom use to prevent from HSV-2 and other sexually transmitted diseases among them.

OBJECTIVETo analyze the prevalence rates and associated risk factors on HIV, syphilis, herpes simplex virus-2 (HSV-2) among female sex workers (FSWs) in Jiaozhou, Shandong province.

METHODSThrough convenient sampling, an anonymous questionnaire survey was conducted on female sex workers to collect related information. Blood specimens were drawn for serological tests on HIV, syphilis and HSV-2 antibodies, respectively. Patients with positive results from both treponema pallidum and HSV-2 tested by ELISA method, were defined as being superinfected.

RESULTSA total of 460 FSWs were recruited in this study. The prevalence rates of HIV, syphilis, HSV-2, and syphilis/HSV-2 superinfection were 0.22% , 5.9% , 43.0% , and 11.7% , respectively. Among the methamphetamine users, the prevalence rates of syphilis, HSV-2, and syphilis/HSV-2 superinfection were 12.4%, 55.2%, and 22.9%, respectively. Results from multivariate analysis showed that factors that significantly associated with syphilis infection would include: methamphetamine use (OR = 3.61, 95% CI:1.62-8.06), having first commercial sex intercourse at under 20 years of age (OR = 2.80, 95% CI:1.15-6.85), more than 2 establishments that the FSWs worked in the last month (OR = 4.37, 95%CI:0.83-22.83). Factors associated with HSV-2 infection were methamphetamine use (OR = 2.30, 95%CI:1.43-3.70), having first commercial sex intercourse at under 20 years of age (OR = 1.77, 95% CI:1.16-2.69), working at low-end establishments (OR = 2.61, 95%CI:1.66-4.10), working at the local sex-work venues for more than one year (OR = 2.01, 95% CI:1.28-3.14), with low education backgrounds (OR = 2.27, 95% CI:1.18-4.36), using methamphetamine (OR = 3.95, 95% CI:2.09-7.44), low education background (OR = 2.43, 95% CI: 1.10-5.36), 21-30 year-olds (OR = 2.95, 95%CI:1.08-8.03), older than 31 years of age (OR = 7.05, 95% CI:2.48-20.01) etc., were independent risk factors associated with the superinfection of syphilis and HSV-2.

CONCLUSIONThe prevalence rates of syphilis, HSV-2 and syphilis/HSV-2 superinfection were relatively high among FSWs in Jiaozhou, especially among the FSWs who were methamphetamine users.

OBJECTIVETo explore the prevalence of syphilis and HSV-2 among female sex workers (FSWs) who use new types of drugs in Jiaozhou city.

METHODSThrough convenient sampling, an anonymous questionnaire survey was conducted among female sex workers to collect demographic characteristics, new-type drugs abusing characteristics and related sexual behaviors from October to December, 2013. Blood specimens were drawn for serological tests of syphilis antibody and HSV-2 antibody. Urine specimens of the subjects surveyed were collected to test for methamphetamine. Differences in demographic characteristics, new-type drug abusing characteristics, and sexual behaviours between drug-abusing FSWs and non-drug-abusing FSWs were compared by t-test and χ(2)-test.

RESULTSA total of 460 FSWs were recruited in this study, and 105 FSWs admitted their drug abuse history. Among the 341 urine specimens confirmed to be methamphetamine positive, there were 3 FSWs claimed that they never abuse new-type drugs. The rate of new-type drug abuse was 23.5% (108/460). A total of 71.4% (75/105) of the new drug-abusing FSWs started using drugs under 25 years old. The main reasons for drug abuse were clients request (24, 22.9%), making more money (23, 21.9%) and companion temptations (22, 21.0%). Totally, 41.9% of them (44/105) took drugs with 4-5 persons, 32.4% (34/105) had sex with 2-3 men after taking drugs, and 60.2% of new-type drug-abusing FSWs (65/108) used condoms in the latest commercial intercourse, while only 7.4% FSWs (8/108) used condoms every time during their commercial sex activities in the recent month. Compared with FSWs having no drug abuse behavior, drug-abusing FSWs had higher single proportion (73.2% (79/108) vs 63.6% (224/352), χ(2) = 8.64, P < 0.05), lower condom use rate in the recent month (7.4% (8/108) vs 22.7% (80/352), χ(2) = 12.53, P < 0.01) and higher pregnancy rate in the recent 6 months (24.1% (26/108) vs 8.8% (31/352), χ(2) = 17.74, P < 0.01) and most of them come from the middle and high-level entertainmens (78.7% (85/108) vs 65.1% (229/352), χ(2) = 13.09, P < 0.01). Among the new-type drug-abusing FSWs, the prevalence rates of syphilis and HSV-2 were 12.0% (13/108) and 55.6% (60/108) , respectively. A total of 33 FSWs claimed that they were diagnosed with STDs in the recent year (30.6%) . The rates of syphilis(12.0% (13/108) vs 4.0% (14/352), χ(2) = 9.72, P < 0.01), HSV-2(55.6% (60/108) vs 39.2% (138/352), χ(2) = 9.01, P < 0.01) and diagnosed STDs (30.6% (33/108) vs 17.9% (63/352), χ(2) = 8.02, P < 0.01) among the drug-abusing FSWs were significantly higher than those of non-drug-abusing FSWs.

CONCLUSIONThere is a higher proportion of new-type drug abuse among the FSWs in Jiaozhou, with significantly higher prevalence rates of syphilis and HSV-2 infection, compared with non-new types of drug abusing FSWs. Prevalent risk sexual behaviors and ignorance of new-types drugs' harm were seen among them.
