Objective: to determine the incidence of sexually transmitted infections in child and adolescent consultation. Methods: an observational, descriptive, transversal study was conducted whose universe were all patients with diagnosis of sexually transmitted infections who attended child and adolescent consultation of pediatric specialty clinic, Camagüey, from September 1st, 2017 to August 31st, 2018, they were 50. The variables studied were: age groups, marital status, type of sexually transmitted infection, association with other sexually transmitted infections, predisposed factors for acquisition (sexual risk behavior, cervicitis and antecedents of former sexually transmitted infections), and sexual preferences. The information obtained was processed using the statistical package SPSS for Microsoft Excel 2017. The methods used were descriptive statistics distribution of absolute and relative frequencies. The results were presented in tables. Results: the most affected age group was between 13 to 15 years, singles and heterosexual. Vaginal candidiasis was predominated, followed by genital warts. About half of the patients have not transmitted infections consociated. Genital warts were the most consociated. The risk factors that prevailed were antecedents of former sexually transmitted infections and sexually risky sexual behavior. In the last one predominated early sexual life and frequent change of partner. Conclusions: these results show the necessity of sexual education for the adolescents to have a healthy sexuality (AU)

Sexual Abuse and Sexually-Transmitted HIV/AIDS in Jamaican Children and Adolescents Aged 6-19 Years.

INTRODUCTION: Risk factors and outcomes of sexually-acquired human immunodeficiency virus infection were characterized in Jamaican children and adolescents. METHODOLOGY: Management was carried out by multidisciplinary teams in Infectious Diseases clinics during August 2003 through February 2019 using modified World Health Organization HIV criteria. RESULTS: There were 78 clients, aged 6 to 19 years, with females:males = 4:1 (p < 0.05). Sexual-initiation occurred in 60%, 47 before < 16 years (median 13 years, with four < 10 years; females:males = 7:1). Sexual-initiation preceded HIV diagnosis in all cases (median 2 years). Secondary education 93% (69/77) and living with non-parental relatives 17% (13/78) were associated with early sexual-initiation (p < 0.042); as was later imprisonment in 6% (3/52). Other sexually transmitted infections 36% (19/53) were associated with sexual-initiation ≥ 16 years (p < 0.01). Risks for ongoing HIV-transmission included infrequent condom use 74% (39/53), body-piercings 50% (24/48), illicit drug use 37% (28/76), tattoos 36% (19/52), transactional sex 14% (7/53) and pregnancy 56% of girls. 77% (59/77) had Centres for Diseases Control's Category A HIV infection; 82% (61/75) initiated anti-retroviral therapy; 75% (56/75) had first-line drugs, with helper T lymphocyte counts ≥ 500 cells/µL in 61% (48/78) and HIV viral load of < 1,000 copies/µL in 63% (40/64). Complications included dermatological 39% (20/52), respiratory 25% (13/52) and neurological 15% (8/52). Early sexual initiation was associated with depression 43% (33/76; p < 0.004) and suicidal attempt or ideation 23% (18/77; p < 0.096). Four (5%) died. CONCLUSIONS: Sexually transmitted HIV/AIDS in children and adolescents should preempt prompt medical, legal and psychosocial interventions.

HIV-1 molecular transmission network among sexually transmitted populations in Liaoning Province, China.

INTRODUCTION: In recent years, with the development of molecular epidemiology, molecular transmission networks based on evolutionary theory and sequence analysis have been widely used in research on human immunodeficiency virus (HIV)-1 transmission dynamics and precise intervention for high-risk populations. The HIV-1 molecular transmission network is a new method to study the population's access to the network, the characteristics of clustering, and the characteristics of interconnection in the network. Here, we analyzed the characteristics of the HIV-1 molecular transmission network of sexually transmitted people in Liaoning Province. METHODS: A study of HIV-infected persons who were sexually transmitted in Liaoning Province from 2003 to 2019. HIV-1 RNA was extracted, amplified and sequenced, and a phylogenetic tree was constructed to determine the subtype using the well matched pol gene region sequence. The gene distance between sequences was calculated, the threshold was determined, and the molecular transmission network was constructed. RESULTS: 109 samples of pol gene region were obtained. The main subtype of HIV-1 was CRF01_AE, followed by B, CRF07_BC, etc. 12.8% of them were resistant to HIV. At the threshold of 0.55 gene distance, 60.6% of them entered the HIV-1 molecular transmission network. Workers, sample source voluntary counseling and testing, other testing, subtype B and drug resistance are the factors influencing the access to HIV-1 molecular transmission network. The subtype of CRF01_AE formed 6 clusters in the molecular transmission network. In the network, the difference of connection degree between different subtypes was statistically significant. DISCUSSION: The three subtypes CRF01_AE, CRF07_BC and B that enter the molecular transmission network do not have interconnections, and they form clusters with each other. It shows that the risk of transmission among the three subtypes is less than the risk of transmission within each subtype. The factors affecting HIV-1 entry into the molecular transmission network were occupation, sample source, genotype and drug resistance. The L33F mutation at the HIV-1 resistance mutation site constitutes the interconnection in the largest transmission cluster in the network. The epidemiological characteristics of HIV-infected persons in each molecular transmission cluster show that 97% of the study subjects come from the same area and have a certain spatial aggregation. CONCLUSION: Constructing a molecular transmission network and conducting long-term monitoring, while taking targeted measures to block the spread of HIV can achieve precise prevention and control.

Viral Venereal Diseases of the Skin.

Viral venereal diseases remain difficult to treat. Human papilloma virus (HPV) and herpes simplex virus (HSV) are two common viral venereal diseases. HPV infections are characterized by anogenital warts and less commonly by premalignant or malignant lesions. HSV infections classically present as grouped vesicles on an erythematous base with associated burning or pain; however, immunosuppressed patients may have atypical presentations with nodular or ulcerative lesions. This review discusses the epidemiology, diagnosis, and management of anogenital HPV and HSV infections with an emphasis on treatment modalities for the practicing dermatologist. Diagnosis of these diseases typically relies on clinical assessment, although multiple diagnostic techniques can be utilized and are recommended when diagnosis is uncertain or evaluating an individual with increased risk of malignancy. Management of HPV and HSV infections involves appropriate counseling, screening, and multiple treatment techniques. Particularly for HPV infections, a practitioner may need to use a combination of techniques to achieve the desired outcome.

Risk of Sexually Transmitted Zika Virus in a Cohort of Economically Disadvantaged Urban Residents.

To understand the disease burden of sexually transmitted Zika virus (ZIKV), we prospectively followed a cohort of 359 adult and adolescent residents of an urban community in Salvador, Brazil, through the 2015 ZIKV epidemic. Later, in 2017, we used a retrospective survey to associate sexual behavior during the epidemic with ZIKV infection as defined by immunoglobulin G3 NS1 enzyme-linked immunosorbent assay. We found that males who engaged in casual sexual encounters during the epidemic were more likely (adjusted odds ratio, 6.2 [95% confidence interval, 1.2-64.1]) to be ZIKV positive, suggesting that specific groups may be at increased risk of sexually transmitted infections.

Follow-Up Household Serosurvey in Northeast Brazil for Zika Virus: Sexual Contacts of Index Patients Have the Highest Risk for Seropositivity.

BACKGROUND: Zika virus (ZIKV) is a mosquito-borne virus that is also transmitted sexually; however, the epidemiological relevance of ZIKV sexual transmission in endemic regions is unclear. METHODS: We performed a household-based serosurvey in Northeast Brazil to evaluate the differential exposure to ZIKV and chikungunya virus (CHIKV) among households. Individuals who participated in our previous arboviral disease cohort (indexes) were recontacted and enrolled, and their household members were newly enrolled. RESULTS: The relative risk of sexual partners being ZIKV-seropositive when living with a ZIKV-seropositive index participant was significantly higher, whereas this was not observed among nonsexual partners of the index. For CHIKV, both sexual and nonsexual partner household members living with a CHIKV-seropositive index had a significantly higher risk of being seropositive. In the nonindex-based dyadic and generalized linear mixed model analyses, the odds of sexual dyads having a concordant ZIKV plaque reduction neutralization test result was significantly higher. We have also analyzed retrospective clinical data according to the participants' exposure to ZIKV and CHIKV. CONCLUSIONS: Our data suggest that ZIKV sexual transmission may be a key factor for the high ZIKV seroprevalence among households in endemic areas and raises important questions about differential disease from the 2 modes of transmission.

Prevalence and Genotypes of Human Papillomavirus among Men in Yunnan Province, China.

Human papillomavirus (HPV) infection is one of the most commonly reported sexually transmitted infections. Persistent infection is associated with the development of cervical cancer. Men may serve as a medium for HPV transmission among women, and much remains unknown about the prevalence and genotypes of HPV infection among men in Yunnan Province. This study was designed to investigate these parameters among men in this region. Clinical information was collected from January 2015 to May 2020, and 369 men who wished to undergo tests for HPV were included in this study. HPV screening was performed using the HPV GenoArray Test Kit, and the anatomical site of sample collection was the urethra. The mean age was 36.15 ± 9.08 years. Our results revealed that the prevalence of HPV infection among men was 23.85% in Yunnan Province, and there was no association between age and HPV prevalence in men. There were 72 (81.81%) individuals positive for a single HPV type, and 16 (18.19%) positive for multiple HPV types. The most prevalent oncogenic HPV types were found to be 52, 51, and 16. The most prevalent types of HPV infection were similar between men and women in this region, though the prevalence of HPV in men was relatively high.

Time-trend of hospitalizations for anogenital warts in Veneto region in the HPV vaccination era: a cross sectional study (2007-2018).

BACKGROUND: Human papillomavirus (HPV) is a common sexually transmitted pathogen and the cause of several cancers and of anogenital warts. With this study, we estimated the trend of hospitalizations for anogenital warts (AGWs) in the Veneto region (Italy) from 2007 to 2018. METHODS: The analysis included all the hospital discharge records of public and accredited private hospitals occurred in Veneto residents in the timespan 2007-2018. The ICD9-CM code 078.11 considered were those associated with condyloma acuminatum and those associated with surgical interventions for vulval/vaginal warts, penile warts anal warts. Annual total and sex- and age-specific hospitalization rates and trends were calculated and correlated with the different HPV vaccine coverage over the study period. RESULTS: We observed an overall reduction of hospitalization rates for AGWs: from 15.0 hospitalizations every 100,000 Veneto residents in years 2007-08 to 10.9 hospitalizations every 100,000 Veneto residents in year 2017-18 (- 37.4%; p < 0.05). Reduction has been caused by a drop in hospitalizations in females - from a rate of 20.4/100,000 in 2007-2008 to a rate of 10.8/100,000 in 2017-18 (AAPC: -7.1; 95%CI: - 10.6;-3.4); while in males, we observed a slight - but not statistically significant - increase in hospitalization rates. CONCLUSION: The marked decline in hospitalization rates for AGWs in Veneto Region is probably attributable to the high coverage rates of HPV vaccination programs implemented since 2008.

Review on the molecular epidemiology of sexually acquired hepatitis C virus infection in the Asia-Pacific region.

INTRODUCTION: Sexual acquisition has emerged as a transmission route for hepatitis C virus (HCV) of growing importance among human immunodeficiency virus (HIV)-positive populations. In Western countries, HCV epidemics have been increasingly detected among men who have sex with men (MSM). This review describes the molecular epidemiology of sexually acquired HCV infection in the Asia-Pacific region. METHODS: A systematic search was performed on PubMed in March 2019. Either abstract or full-text of each publication in the search results was screened for eligibility. Studies from different countries/cities involving eligible cases, who acquired HCV sexually with identified subtype, were synthesized for the evaluation of molecular epidemiology in the Asia-Pacific region. Two large-scale systematic reviews on the genotype distribution of HCV at a population level and among PWID were used as references for comparison. RESULTS AND DISCUSSION: Overall, 13 full-text articles with 549 subjects originating from nine countries/cities were reviewed. A total of five genotypes and 14 subtypes were identified, dominated by subtypes 1b (23.0%), 2a (19.1%) and 3a (29.5%). A majority of the infected cases occurred in HIV-positive MSM. In some places, notably Hong Kong, India and Indonesia, the predominant subtype in sexually acquired HCV infection in MSM was different from that circulating in the general population. Shared transmission networks between people who inject drugs (PWID) and MSM were shown in Australia and New Zealand, whereas overlapping risk elicited from a small number of subjects existed in Tokyo, Taipei and Guangxi. MSM-specific clusters were identified in Hong Kong, Taipei and Hubei. CONCLUSIONS: The distribution of sexually acquired HCV was sparsely scattered across countries/cities in the Asia-Pacific region. The threat of overlapping risk differed by locations, whereas transnational outbreaks remained uncommon. The paucity of information has hindered progress with comprehensive assessment in the Asia-Pacific region, where seroprevalence of HCV among HIV-positive MSM was relatively high.

Twenty-First Century Viral Pandemics: A Literature Review of Sexual Transmission and Fertility Implications in Men.

INTRODUCTION: The 21st century has seen a series of viral pandemics that have collectively infected millions of individuals. To understand factors that may contribute to viral spread and address long-term health sequelae for survivors, it is important to review evidence regarding viral presence in semen, sexual transmission potential, and possible effects on fertility. AIM: To review the current literature regarding the sexual transmissibility of recent viral pandemics and their effects on semen parameters and fertility. We review evidence for the following viruses: Ebola, Zika, West Nile, pandemic influenza, severe acute respiratory syndrome (SARS), and SARS-corona virus-2 (SARS-CoV-2). METHODS: A literature search was conducted to identify relevant studies. Titles and abstracts were reviewed for relevance. References from identified articles were searched and included, if appropriate. MAIN OUTCOME MEASURES: The main outcome measure of this study was reviewing of peer-reviewed literature. RESULTS: Both the Ebola virus and Zika virus are present in semen, but only the Zika virus shows consistent evidence of sexual transmission. Current evidence does not support the presence of the West Nile virus, pandemic influenza, SARS, and SARS-CoV-2 in semen. The Zika virus appears to alter semen parameters in a way that diminishes fertility, but the effect is likely time limited. The West Nile virus and SARS have been associated with orchitis in a small number of case reports. Viruses that cause febrile illness, such as pandemic influenza, SARS, and SARS-CoV-2, are associated with decreased sperm count and motility and abnormal morphology. SARS and SARS-CoV-2 may interact with angiotensin-converting enzyme 2 receptors present in the testes, which could impact spermatogenesis. CONCLUSIONS: We have reported the presence in semen, sexual transmission potential, and fertility side effects of recent viral pandemics. Overall, semen studies and fertility effects are highly understudied in viral pandemics, and rigorous study on these topics should be undertaken as novel pandemics emerge.

Estimation of mosquito-borne and sexual transmission of Zika virus in Australia: Risks to blood transfusion safety.

BACKGROUND: Since 2015, Zika virus (ZIKV) outbreaks have occurred in the Americas and the Pacific involving mosquito-borne and sexual transmission. ZIKV has also emerged as a risk to global blood transfusion safety. Aedes aegypti, a mosquito well established in north and some parts of central and southern Queensland, Australia, transmits ZIKV. Aedes albopictus, another potential ZIKV vector, is a threat to mainland Australia. Since these conditions create the potential for local transmission in Australia and a possible uncertainty in the effectiveness of blood donor risk-mitigation programs, we investigated the possible impact of mosquito-borne and sexual transmission of ZIKV in Australia on local blood transfusion safety. METHODOLOGY/PRINCIPAL FINDINGS: We estimated 'best-' and 'worst-' case scenarios of monthly reproduction number (R0) for both transmission pathways of ZIKV from 1996-2015 in 11 urban or regional population centres, by varying epidemiological and entomological estimates. We then estimated the attack rate and subsequent number of infectious people to quantify the ZIKV transfusion-transmission risk using the European Up-Front Risk Assessment Tool. For all scenarios and with both vector species R0 was lower than one for ZIKV transmission. However, a higher risk of a sustained outbreak was estimated for Cairns, Rockhampton, Thursday Island, and theoretically in Darwin during the warmest months of the year. The yearly estimation of the risk of transmitting ZIKV infection by blood transfusion remained low through the study period for all locations, with the highest potential risk estimated in Darwin. CONCLUSIONS/SIGNIFICANCE: Given the increasing demand for plasma products in Australia, the current strategy of restricting donors returning from infectious disease outbreak regions to source plasma collection provides a simple and effective risk management approach. However, if local transmission was suspected in the main urban centres of Australia, potentially facilitated by the geographic range expansion of Ae. aegypti or Ae. albopictus, this mitigation strategy would need urgent review.

Human papillomavirus epidemiology in populations with normal or abnormal cervical cytology or cervical cancer in the Middle East and North Africa: A systematic review and meta-analysis.

BACKGROUND: Human papillomavirus (HPV), one of the most common sexually transmitted viral infections worldwide, is the leading cause of cervical cancer. In Middle East and North Africa (MENA) Region HPV data is at scarce, and most of the countries haven't implemented any vaccination programs. This present meta-analysis and systematic review aimed to describe human papillomavirus (HPV) epidemiology by clinical subgroups in the (MENA) region. METHODS: Studies assessing HPV prevalence rates were systematically reviewed, and the selected articles were reported following the PRISMA guideline. Random-effects meta-analyses and meta-regression were used to estimate HPV pooled mean prevalence rates and their association with other factors. RESULTS: For the cervical cancer population in the MENA region, the pooled HPV prevalence rate was 81% (95% CI, 70%-90%). HPV detected in cervical cancer samples was most prevalent in the Maghreb countries (88%; 95% CI, 78%-96%) and least prevalent in Iran (73%; 95% CI, 62%-83%).For the subgroup with abnormal-cervical cytology in the MENA region, the pooled HPV prevalence rate was 54% (95% CI, 41%-67%), with the highest prevalence reported in Northeast Africa (94%; 95% CI, 91%-96%), and the lowest prevalence in the Levant region (31%; 95 CI, 16%-49%). In the general population subgroup in the MENA region, the pooled HPV prevalence rate was 16% (95% CI, 14%-17%), HPV was most prevalent in the Northeast Africa region (21%; 95 CI, 7%-40%) and least prevalent in the Levant region (7%; 95 CI, 2%-14%). CONCLUSION: The present meta-analysis comprehensively described the current HPV prevalence rates in the MENA region and found that the rates have continued to increase with time, especially in African regions. Designing personalized awareness and vaccination programs that respect the various cultural and religious values remains the main challenge in prevention of cervical cancer in the MENA region.

Sexual transmission of Zika virus on Twitter: A depoliticised epidemic.

During global health crises, different narratives regarding infectious disease epidemics circulate in traditional media (e.g. news agencies, television channels) and social media. Our study investigated the narratives related to sexual transmission of Zika virus that circulated on Twitter during a public health emergency and analyzed the relationship between information on Twitter and on traditional media. We examined 10,748 tweets posted during the peaks of Twitter activity between January and March 2016. Posts in English, Spanish, French, and Portuguese and websites linked to tweets were manually reviewed and analyzed thematically. During the study period, there were three peaks of Twitter activity related to the sexual transmission of Zika. Most tweets in the first peak (n = 412) had humorous/sarcastic content (55%). Most tweets in the second and third peaks (n = 5,154 and n = 5,182, respectively) disseminated information (>93%). Across languages, textual and visual content on the websites were predominantly placed online by traditional media and highlighted epidemiological narratives published by public health agencies, with little or no mention of the concerns or experiences of individuals most affected by Zika. Prioritising epidemiological/clinical aspects of epidemics may have a depoliticising effect and contribute to overlooking socio-economic determinants of the Zika epidemic and issues related to reproductive justice.

Brief Report: Group Sex and Methamphetamine Use Fuel an Explosive Epidemic of Hepatitis C Among HIV-Infected Men Who Have Sex With Men in Bangkok, Thailand.

BACKGROUND: Increased rates of hepatitis C virus (HCV) infection among HIV-infected men who have sex with men (MSM) and who deny injecting drugs have been reported in resource-rich settings. SETTING: We measured HCV prevalence and incidence in a predominantly MSM cohort with acute HIV infection in Bangkok, Thailand. METHODS: In 2009-2018, participants with acute HIV infection were enrolled into the SEARCH010/RV254 cohort. HCV antibody was measured at enrollment and at least once annually. Infection was confirmed with HCV RNA. Risk factors for HCV were analyzed by proportional hazards regression, with hazard ratios (HRs) calculated in a multivariable model. RESULTS: Of 573 participants, 94% were MSM, with a median age of 26 years (range 18-70 years). The prevalence of HCV antibody was 9 of the 573, or 1.6% [95% confidence interval (CI): 0.7% to 3.0%]. In 1883 person-years (PY) of follow-up, 39 incident cases were identified (20.7 per 1000 PY, 95% CI: 15.1 to 28.3). All incident cases were identified from 2014 onward, and incidence rose from a range of 7.5-11.4 per 1000 PY between 2014 and 2016 to 44.8 per 1000 PY in 2018 (P = 0.001). Most cases (97.4%) were MSM and denied injecting drugs (37 of the 39, 94.5%). In multivariate analysis, methamphetamine use [adjusted HR 2.33 (95% CI: 1.13 to 4.8), P = 0.022], group sex [adjusted HR 2.54 (95% CI: 1.26 to 5.12), P = 0.009], and a history of positive Treponema pallidum hemagglutination or rapid plasma reagin [adjusted HR 2.43 (95% CI: 1.22 to 4.85), P = 0.012] were significantly associated with incident HCV. CONCLUSION: We report an HCV epidemic among this cohort of HIV-infected Bangkok-based MSM. Access to timely HCV diagnosis and treatment is needed to prevent morbidity and to decrease onward transmission.

Temporal trend of HIV/AIDS cases in the state of Minas Gerais, Brazil, 2007-2016. / Tendência temporal dos casos de HIV/aids no estado de Minas Gerais, 2007 a 2016.

OBJECTIVE: to analyze the temporal trend of Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) incidence, detection and mortality coefficients in the state of Minas Gerais between 2007 and 2016. METHODS: this was a time series study of data held on the Notifiable Health Conditions Information System (Sinan) using Prais-Winsten regression. RESULTS: in the period studied, 35,349 cases were notified, with predominance of sexually transmitted cases (81.7%), 50.3% of which were heterosexual cases and 22.8% were homosexual cases. AIDS incidence increased (annual change 1.6%; 95%CI 0.0;3.3) as did HIV detection (annual change 60.3%; 95%CI 22.9;109.0). The mortality rate was stationary; HIV+ notifications increased from 3.8% in 2007 to 65.1% in 2016. CONCLUSION: the growing trend of HIV+ detection coincided with the government strategy to identify cases. AIDS incidence increased.

Prevalence of HPV infection among sexually active adolescents and young adults in Brazil: The POP-Brazil Study.

For Brazil, there are no nationwide data on HPV prevalence against which the impact of the HPV immunization program can be measured in the future. Therefore, we aim to evaluate the prevalence of genital HPV infection among adolescents and young adults in Brazil. A cross-sectional, multicentric, nationwide survey was conducted between September 2016 and November 2017. Sexually active unvaccinated women and men aged 16 to 25 years old were recruited from 119 public primary care units, including all 26 state capitals and the Federal District. All participants answered a face-to-face interview and provided biological samples for genital HPV analysis. We used an automated DNA extraction method and HPV genotyping was performed using the Linear Array genotyping test (Roche). Of 7,694 participants, 53.6% (95% CI 51.4-55.8) were positive for any HPV type. The prevalence of high-risk HPV types was significantly higher in women (38.6% vs. 29.2%, P < 0·001). The HPV types included in the quadrivalent vaccine were detected in 1002 (14.8%) specimens, with a different pattern of HPV infection between sexes. Characteristics associated with overall HPV detection included female gender, self-declaration of race as brown/pardo, lower socioeconomic class, single or dating, current smoking and having 2 or more sex partners in the past year. We found a high prevalence of HPV, with significant differences between regions. Our data provide information that may be considered when developing HPV prevention policies and constitute a baseline against which the impact of the HPV immunization program in Brazil can be measured in future years.
