Sexually Transmitted Infection Transmission Dynamics During the Coronavirus Disease 2019 (COVID-19) Pandemic Among Urban Gay, Bisexual, and Other Men Who Have Sex With Men

Prevalence of sexually transmitted infections (STIs) among first time visitors at STIs clinic in Hangzhou, China: Assessing the influence of the COVID-19 pandemic

BACKGROUND

This study assesses the prevalence of sexually transmitted infections (STIs) in first time visitors to the STIs clinic in Hangzhou, China, considering different genders, ages and symptoms. And also explores howthe COVID-19 pandemic has affected on STIs.

METHODS

From 2019 to 2023, 27,283 first time visitors were tested for nine distinct STIs, including Human Papillomavirus (HPV), Human Immunodeficiency Virus (HIV), syphilis, Herpes Simplex Virus type 2 (HSV-2), Ureaplasma urealyticum (UU), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), and vaginal Candida.

RESULTS

Symptomatic male and female visitors showed overall STI-positive rates of 39.27% and 59.20%, respectively(p < .001). The top three pathogens in both genders were HPV (47.56% and 56.71%), UU (29.21% and 56.47%), and HSV-2 (22.41% and 52.94%). Among asymptomatic visitors, the total STI-positive rate was 36.63% in males and 52.03% in females. Age-stratified analysis revealed higher STI rates in visitors ≤ 20 or >50 years, regardless of gender and symptoms. During the COVID-19 pandemic, symptomatic visitors showed lower positive rates for HPV, HIV, syphilis, and HSV-2, while Candida, UU, CT, NG, and multiple infections increased. Among asymptomatic visitors, HPV had the lowest positive rate, while NG and multiple infections increased during the pandemic.

CONCLUSION

STI prevalence is notably high, particularly in those aged ≤ 20 and >50 years. It emphasizes the need for enhanced health education, condom use, and vaccination. The COVID-19 pandemic impacting STIs through varied factors, such as reduced sexual activity and clinical service interruption.

Incidence of Sexually Transmitted Infections in Youth with HIV During Pre-COVID and COVID Era

Adolescents and young adults (AYAs) living with HIV have high rates of co-sexually transmitted infections (STIs). During the coronavirus disease (COVID) pandemic, STI prevention strategies, including access to testing/treatment facilities, availability of health care workers, and condom availability, may have decreased. This study aimed to determine if differences in STI incidence for first infection and reinfection existed between the pre-COVID and COVID eras in a cohort of AYAs living with HIV in Atlanta, GA. Retrospective chart review was conducted for all patients between ages 13 and 24 at the Grady Ponce Clinic. Two eras were identified: a pre-COVID era (January 1, 2009-December31, 2019) and a COVID era (January 1, 2020-June 30, 2021). STIs recorded included gonorrhea, chlamydia, human papillomavirus, syphilis, trichomonas, herpes simplex virus, lymphogranuloma venereum, hepatitis C, bacterial vaginosis, and chancroid. First and recurrent incidence rates for any STIs were reported. Our sample included 766 sexually active AYAs with HIV. A total of 721 patients were included in the pre-COVID era and 583 (80.9%) had at least one STI. A total of 337 patients were included in the COVID era, and 158 had at least one STI (46.9%). The overall first STI incidence rate increased from 42.47 to 58.67 per 100 person-years (PY) and the recurrent STI incidence rate increased from 121.50 to 169.85 per 100 PY from the pre-COVID to the COVID era (p < 0.001). Our study demonstrated significantly higher incidence rates of first and recurrent STIs in AYAs living with HIV in the COVID era. We urge continuation of existing STI prevention programs to avoid secondary clinical and economic adverse effects of increased infections.

Orogenital and anal infection by Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and other sexually transmitted infections in men who have sex with men in Lisbon

BACKGROUND

Men who have sex with men (MSM) are at risk for sexually transmitted infections (STIs), but more data on extragenital carriage are needed.

AIM

We assessed the genital and extragenital prevalence of bacterial and other STIs in MSM in a Lisbon sexual health clinic.

METHODS

We screened oral, anal, and urine samples of MSM visiting the GAT-CheckpointLX clinic June 2017-December 2021 for Chlamydia trachomatis (including lymphogranuloma venereum, LGV), Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, Mycoplasma hominis, Ureaplasma urealyticum, and U. parvum. Ano-oro-genital lesions were tested for LGV, Treponema pallidum, and Herpes Simplex Virus. Blood was tested for HIV and T. pallidum antibodies.

RESULTS

N. gonorrhoeae was found in 16.6% of the MSM followed by C. trachomatis (13.2%), M. genitalium (10.3%) and T. vaginalis (0.2%). The most frequent occurrence was anorectal (C. trachomatis, M. genitalium) and oral (N. gonorrhoeae). We found high carriage of U. urealyticum (36.1%) and M. hominis (22.1%). LGV was detected in 21.8% of chlamydia-positive anorectal swabs. Syphilis was detected in 22.6% of tested MSM, while 13.8% had HIV. Gonorrhoea and chlamydia were significantly more prevalent in MSM with concomitant HIV or syphilis.

CONCLUSION

The substantial extragenital prevalence of bacterial STIs in MSM, and HIV and syphilis coinfections, suggest screening has value in identifying hidden carriage and in contributing for providing better care.

Sexual Behavior and Sexual Decision-Making Among Gay, Bisexual, and Other Men Who Have Sex with Men During the COVID-19 Pandemic: Observations from a Rapid Ethnographic Assessment in Marion County, Indiana, October-November 2021

From 2020 to 2021, Marion County, Indiana, USA, saw an increase in early syphilis diagnoses, primarily among gay, bisexual, and other men who have sex with men (GBMSM). This rapid ethnographic assessment combines survey data from GBMSM with data from key informant interviews with multiple groups of stakeholders, including GBMSM, to describe how COVID-19 impacted sexual behaviors, sexual decision-making, and access to sexually transmitted disease (STD) services among GBMSM in Marion County, Indiana. A total of 62 virtual, semi-structured qualitative interviews with 72 key respondents including health department staff, medical providers, community-based organization staff, and GBMSM were conducted from October 14 to November 22, 2021. Modifications to partner-seeking and sexual behaviors attributable to the pandemic were associated with the way in which individuals reacted to the pandemic in general. Some GBMSM adopted mitigation strategies to avoid COVID-19 when meeting sex partners, such as creating a "sex pod." Effects on mental health included increased loneliness, heightened anxiety, and a sense of hopelessness regarding the perceived inevitability of acquiring COVID-19. For some, the latter prompted decreased engagement in preventive measures when engaging in sexual activity. The pandemic decreased access to STD services and significantly curtailed public health outreach efforts, which may have limited access to needed STD treatment and care. Efforts focusing on ongoing public health concerns during extreme health events like COVID-19 may want to consider the many ways these events affect ancillary behaviors, such sexual decision-making and sexual behaviors. The role of mental health is key; messaging and guidance may benefit from a trauma-informed approach.

Association between where men who have sex with men (MSM) meet sexual partners and chlamydia/gonorrhoea infection before and during the COVID-19 pandemic in San Diego, California

BACKGROUND

Meeting sex partners online is associated with increased risk of acquiring sexually transmitted infections. We examined whether different venues where men who have sex with men (MSM) meet sex partners was associated with prevalent Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infection, and whether prevalence increased during (vs before) the COVID-19 pandemic.

METHODS

We conducted a cross-sectional analysis of data from San Diego's 'Good To Go' sexual health clinic from two enrolment periods: (1) March-September 2019 (pre-COVID-19) and (2) March-September 2021 (during COVID-19). Participants completed self-administered intake assessments. This analysis included males aged ≥18 years self-reporting sex with males within 3 months before enrolment. Participants were categorised as (1) meeting new sex partners in-person only (eg, bars, clubs), (2) meeting new sex partners online (eg, applications, websites) or (3) having sex only with existing partners. We used multivariable logistic regression, adjusting for year, age, race, ethnicity, number of sex partners, pre-exposure prophylaxis use and drug use to examine whether venue or enrolment period were associated with CT/NG infection (either vs none).

RESULTS

Among 2546 participants, mean age was 35.5 (range: 18-79) years, 27.9% were non-white and 37.0% were Hispanic. Overall, CT/NG prevalence was 14.8% and was higher during COVID-19 vs pre-COVID-19 (17.0% vs 13.3%). Participants met sex partners online (56.9%), in-person (16.9%) or only had existing partners (26.2%) in the past 3 months. Compared with having only existing sex partners, meeting partners online was associated with higher CT/NG prevalence (adjusted OR (aOR) 2.32; 95% CI 1.51 to 3.65), while meeting partners in-person was not associated with CT/NG prevalence (aOR 1.59; 95% CI 0.87 to 2.89). Enrolment during COVID-19 was associated with higher CT/NG prevalence compared with pre-COVID-19 (aOR 1.42; 95% CI 1.13 to 1.79).

CONCLUSIONS

CT/NG prevalence appeared to increase among MSM during COVID-19, and meeting sex partners online was associated with higher prevalence.

Seroconversion rate of SARS-CoV-2 IgG antibodies and dating behaviour in HIV-PrEP users in a German metropolis during the COVID-19 pandemic

BACKGROUND

At the beginning of the COVID-19 pandemic, when mortality was high, social distance was the only option to prevent transmission of SARS-CoV-2 and prohibit uncontrolled spreading. As the impact of social distancing on sexual behavior was unclear, we aimed to assess the influence of sexual risk behavior on SARS-CoV-2 seroconversion in HIV pre-exposition prophylaxis (PrEP) users after declaration of the pandemic.

METHODS

Prospective study on SARS-CoV-2 IgG-antibody seroconversion rate over time in men having sex with men (MSM) using PrEP at a single tertiary university hospital in Munich, Germany, during quarterly (Q) routine HIV-PrEP visits over 1 year per participant (May 2020 - September 2021). Seroconversion was defined as at least one positive anti-nucleocapsid (anti-N) SARS-CoV-2 IgG antibody test as surrogate for past infection. In addition, sexually transmitted infections (STIs), personal estimated risk behavior and sexual contacts were assessed.

RESULTS

Seroconversion rate during the full observation period was 7.3% (9/124 subjects) by September 2021. Percentage of subjects with symptomatic STIs (T. pallidum, N. gonorrhoeae, C. trachomatis and M. genitalium) was 18.7% in Q3-20, 8.1% in Q4-20, 11.1% in Q1-21, 11.6% in Q2-21 and 9.5% in Q3-21. Perception of subjective threat of SARS-CoV-2 infection and adequacy of preventive measures decreased during the observation period. However, self-reported sex behavior remained stable during the observation period.

CONCLUSIONS

Our cohort showed low proportion of PrEP-users with anti-N IgG by September 2021, comparable to the local incidence. Sexual behavior in this cohort did not change, despite local recommendations for social distancing.

Changes in human papillomavirus prevalence, incidence, and clearance among men who have sex with men in Xinjiang, China after implementation of nonpharmaceutical interventions to control COVID-19: An interrupted time series analysis

OBJECTIVES

This study aimed to assess the effects of COVID-19 nonpharmaceutical interventions (NPIs) on the human papillomavirus (HPV) epidemic among men who have sex with men (MSM) in Xinjiang, China.

METHODS

In our cohort study, we enrolled and followed HIV-negative MSM in Xinjiang, China, between 2016 and 2022. Anal swab samples were collected to test for HPV DNA. We used interrupted time series analysis to characterize the temporal trends in HPV prevalence, incidence, and clearance before (September 01, 2016, to July 16, 2020) and during the implementation of COVID-19 NPIs in Xinjiang (July 17, 2020, to March 31, 2022). We used binomial segmented regression models to estimate the impact of COVID-19 NPIs on HPV prevalence, incidence, and clearance.

RESULTS

We recruited 1296 MSM who contributed to a total of 5374 HPV tests in our study. COVID-19 NPIs were associated with a 37.9% decrease in the prevalence (prevalence ratio, 0.621; 95% confidence interval, 0.465-0.830), 52.2% decrease in the incidence (risk ratio, 0.478; 0.377-0.606), and 40.4% increase in the clearance (risk ratio, 1.404; 1.212-1.627) of HPV of any genotype after the implementation of COVID-19 NPIs in Xinjiang.

CONCLUSION

COVID-19 NPIs may lead to lower transmission and higher clearance of HPV among MSM. Future studies are needed to clarify the longer-term impact of COVID-19 on the transmission and natural history of HPV among MSM.

Change of sexual behavior among men who have sex with men before, during and after COVID-19 pandemic in China: a cross-sectional study

INTRODUCTION

The COVID-19 epidemic control and prevention strategies affected people's sexual activities and behaviors. Little was known about long-term effects of COVID-19 prevention and control strategies on sexual behaviors among men who have sex with men (MSM). This study aimed to examine changes in risky sexual behaviors of MSM before and after the local epidemic.

METHODS

An online survey was conducted nationwide from June 1 to June 10, 2022. MSM aged 16 years and above, residing in China were recruited through convenience sampling. A generalized estimating equation model with modified Poisson regression was used to analyze changes in multiple sexual partners, unprotected sex, mobility for sexual activity, and recreational substance use before and after the local epidemic.

RESULTS

Compared to the pre-pandemic (36.5%), the prevalence of multiple sexual partners (11.5%) significantly decreased during the local epidemic and then increased after the local epidemic (25.2%) but remained lower than pre-pandemic, as did the prevalence of unprotected sex (31.1%, 19.4%, and 26.1%), mobility for sexual activity (7.5%, 2.8%, and 4.1%) and recreational substance use (47.7%, 27.2%, and 39.5%). Compared to the pre-pandemic, higher declines in the prevalence of risky sexual behaviors during the local epidemic existed among MSM living without a regular partner (44% decrease in unprotected sex and 46% in recreational substance use), with a bachelor's degree and above (70% decrease in multiple sex partners, 39% in unprotected sex, 67% in mobility for sexual activity and 44% in recreational substance use), higher incomes (70% decrease in multiple sex partners), self-identified gay or bisexual/unsure (38-71%), and HIV infection (49-83% decrease respectively in these four indicators). After the local epidemic, the declines in the above indicators compared to the pre-pandemic were correspondingly. And higher declines existed among MSM living without a regular partner (8% decrease in unprotected sex and 13% in recreational substance use), with a bachelor's degree and above (33% decrease in multiple sex partners), higher incomes (55% decrease in mobility for sexual activity), self-identified gay (51% decrease in mobility for sexual activity), and HIV infection (32%, 68%, 24% decrease respectively in unprotected sex, mobility for sexual activity and recreational substance use).

CONCLUSIONS

Risky sexual behaviors reduced considerably during the local epidemic, then seemed rebounded after the outbreak but wouldn't return to pre-pandemic levels. More attention should be paid to vulnerable people with lower socio-economic status, HIV-positive, and sexual minorities for sustained HIV and COVID-19 prevention.

Characteristics of Reported Gonorrhea Diagnoses During The COVID-19 Pandemic Compared With Pre-COVID-19 Pandemic, Baltimore City, Maryland

BACKGROUND

Sexual health service disruptions due to COVID-19 mitigation measures may have decreased gonorrhea screening and biased case-ascertainment toward symptomatic individuals. We assessed changes in reported symptoms and other characteristics among reported gonorrhea cases during pandemic versus prepandemic periods in 1 city with persistent gonorrhea transmission.

METHODS

Enhanced surveillance data collected on a random sample of gonorrhea cases reported to the Baltimore City Health Department between March 2018 and September 2021 was used. Logistic regression assessed differences in case characteristics by diagnosis period (during pandemic: March 2020-September 2021; prepandemic: March 2018-September 2019).

RESULTS

Analyses included 2750 (1090 during pandemic, 1660 prepandemic) gonorrhea cases, representing 11,904 reported cases. During pandemic versus prepandemic, proportionally fewer cases were reported by sexual health clinics (8.8% vs 23.2%), and more frequently reported by emergency departments/urgent care centers (23.3% vs 11.9%). Adjusting for diagnosing provider, fewer cases who were men with urethral infections (adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI], 0.55-0.77), aged <18 years (aOR, 0.64; 95% CI, 0.47-0.89), and women (aOR, 0.84; 95% CI, 0.71-0.99) were reported, and cases with insurance (aOR, 1.85; 95% CI, 1.40-2.45), living with human immunodeficiency virus (aOR, 1.43; 95% CI, 1.12-1.83), or recent (≤12 months) gonorrhea history (aOR, 1.25; 95% CI, 1.02-1.53) were more frequently reported during pandemic versus prepandemic. Reported symptoms and same-day/empiric treatment did not differ across periods.

CONCLUSIONS

We observed no changes in reported symptoms among cases diagnosed during pandemic versus prepandemic. Increased frequency of reported diagnoses who were insured, living with human immunodeficiency virus, or with recent gonorrhea history are suggestive of differences in care access and care-seeking behaviors among populations with high gonorrhea transmission during the pandemic.

Advances and challenges in sexually transmitted infections prevention among men who have sex with men in Asia

PURPOSE OF REVIEW

This review summarizes recently published research on sexually transmitted infections (STIs) and sexually transmitted diseases (STDs) among men who have sex with men (MSM) in Asia, covering four main areas: prevalence and consequences of STIs/STDs, factors associated with STI risk, strategies and measures of STI prevention, challenges in the prevention of SITs.

RECENT FINDINGS

Studies show that STIs among Asian MSM are still prevalent, with the prevalence of STIs varying slightly from country to country. In addition to the number of sexual partners, frequency of condom use, high-risk sexual behaviors, the influence of Confucianism, law, and COVID-19 are also related to STI risk. Social stigma, weak health systems, lack of funding and policy support are the current challenges for STIs prevention.

SUMMARY

In the future, new media technologies are encouraged to be used to enhance education and reduce stigma and discrimination against MSM and STIs. Expanding STI screening, strengthening STI knowledge propaganda and education among MSM population, and providing necessary counseling and medical services are main strategies in STI prevention. It is also important to strengthen STI awareness and policy support at the national level.

The Impact of First UK-Wide Lockdown (March-June 2020) on Sexual Behaviors in Men and Gender Diverse People Who Have Sex with Men During the COVID-19 Pandemic: A Cross-Sectional Survey

The global COVID-19 pandemic resulted in strict social distancing measures restricting close physical contact. Men (cis and trans) and other gender diverse people who have sex with men (MGDSM) are at higher risk of sexually transmitted infections (STIs) and may have experienced changes in sexual behavior during government restrictions on social and sexual contact. We aimed to examine self-reported sexual behavior of MGDSM during the first UK-wide lockdown to identify the characteristics of the individuals who might most require sexual health promotion and clinical support. In April-May 2020, we conducted an online survey of MGDSM, promoted on social media and Grindr. Our exploratory approach used descriptive analysis to identify self-reported changes in sexual behavior and performed regression analyses to identify correlates of casual sex during the lockdown. A total of 1429 respondents completed the survey: mean age 36 years, 84% White, 97% male or trans male, 98% assigned male sex at birth, 2% female or non-binary, 65% degree educated or higher. During the lockdown, 76% reported not having any casual sex partners. While the majority reported reduced casual sex, 3% reported an increase in casual sex with one person and 2% with three or more people (group sex). About 12% of the sample engaged in casual sex with only one person and 5% with four or more sexual partners during the lockdown. Reporting casual sex during lockdown was associated with: lower level of education OR = 2.37 [95% CI 1.40-4.01]; identifying as a member of an ethnic minority OR = 2.27[1.40-3.53]; daily usage of sexual networking apps OR = 2.24[1.54-3.25]; being less anxious about contracting SARS-CoV-2 through sex OR = 1.66[1.12-2.44]; using PrEP before lockdown OR = 1.75[1.20-2.56]; continuing to use PrEP OR = 2.79[1.76-4.57]; and testing for STIs during lockdown OR = 2.65[1.76-3.99]. A quarter of respondents remained sexually active with casual partners, indicating a need to provide STI screening services and health promotion targeted to groups most likely to have need over this period. Future research is required to better understand how to support sexual and gender minorities to manage sexual risk in the context of pandemic public health initiatives.
