[PMID: 38293686 PMCID: PMC10825486 DOI: 10.1016/j.idm.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 12/19/2023] [Accepted: 12/19/2023] [Indexed: 02/01/2024] Open
Abstract
Introduction The transmission dynamics of the recent mpox outbreak highlights the lack of infrastructure available to rapidly respond to novel STI outbreaks, of which Asia and Oceania remains particularly susceptible. Here, we simulate outbreaks in this setting and propose the use of pre-emptive vaccination within the men who have sex with men (MSM) community before the arrival and establishment of the virus. Materials and methods Using data driven heterogeneous sexual contact networks, we simulated outbreaks of mpox in Singapore, Hong Kong, and Sydney. An individual based SEIR compartmental model was used to simulate epidemic trajectories and the impact of different vaccination uptakes was assessed in their ability to avert or suppress outbreaks upon the arrival of mpox within the MSM populations. Results The highly dense sexual networks of Singapore and Sydney experience rapid outbreaks, with infection peaks occurring at day 41 and 23 respectively, compared to Hong Kong which occurs at day 77. Across the simulations with no vaccination, 68.2%-89.7% of the MSM community will become infected with mpox across the different cities, over a simulation period of 1 year. By implementing vaccination strategies, the infection rate across the cities can be reduced to as low as 3.1% of the population (range: 3.1%-82.2%) depending on the implementation and uptake of the vaccine. Vaccination is also extremely effective in slowing the start of the epidemic, delaying the epidemic peak by 36-50 days in Hong Kong, or even preventing the outbreak of mpox. Discussion With extremely dense and well-connected sexual contact networks, where 65.2%-83.2% of the population are connected to a super-spreader in the different contact networks, pre-emptive or immediate vaccination upon identification of the first case is strongly recommended to help better manage the outbreak of mpox and prevent potential straining of healthcare systems.

[PMID: 37095388 PMCID: PMC10124926 DOI: 10.1007/s10508-023-02599-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 03/31/2023] [Accepted: 04/03/2023] [Indexed: 05/03/2023]
Abstract
The aim of with this brief report is to examine how the COVID-19 pandemic differentially impacted solitary sexual behaviors in those with and without clinically significant compulsive sexual behavior (CSB). A total of 944 individuals in the United States completed an online cross-sectional survey in October 2020. Participants were asked to retrospectively report their frequency of masturbation and pornography use during the pandemic and prior to the pandemic. Participants also completed assessments of CSB, depression symptoms, and experiences of financial stress caused by the pandemic. Individuals who screened positive for clinically significant CSB reported statistically significant increases in masturbation and pornography use during the pandemic. Those who screened negative for CSB reported no significant increase in masturbation and a very small, statistically significant increase in pornography use. Those screening positive for CSB also reported significantly higher levels of depression symptoms but did not report increased likelihood of experiencing financial distress due to the pandemic. This suggests that increases in masturbation and pornography use reported by some, but not all, recent studies on sexual behaviors during the COVID-19 pandemic may be driven by individuals with CSB. Future research on sexual behaviors during the pandemic should assess CSB to further clarify its relationship with sexual behavior changes.

Changes in Solo and Partnered Sexual Behaviors following the First COVID-19 Wave: Data from an International Study of 26 Countries. INTERNATIONAL JOURNAL OF SEXUAL HEALTH : OFFICIAL JOURNAL OF THE WORLD ASSOCIATION FOR SEXUAL HEALTH 2023; 35:459-480. [PMID: 38601728 PMCID: PMC10903556 DOI: 10.1080/19317611.2023.2224777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 04/21/2023] [Accepted: 05/28/2023] [Indexed: 04/12/2024]
Abstract
Objective To determine individual- and country-level factors associated with self-reported changes in solo and partnered sexual behaviors in an international sample of adults during COVID-19. Methods Data were from the International Sexual Health And REproductive Health during COVID-19 study (I-SHARE)-a cross-sectional, multi-country study (N = 26 countries) assessing adult (N = 19,654) sexual/reproductive health before and during the first wave of COVID-19. We examined self-reported changes (three-point scale: decreased, no change, increased) in solo masturbation, hugging/holding hands/cuddling with a partner, sex with a primary partner, sex with a casual partner, sexting with a partner, viewing sexually explicit media and partnered cybersex. Ordinal regression assessed the impact of individual (age, gender- and sexual-identity, romantic partnership status, employment and income stability, household change and content, mental well-being, changes in alcohol use, and changes in marijuana use) and country-level (e.g., Oxford Stringency Index, Human Development Index, and the Palma Ratio) factors on behavior change. Results The most common behavior to increase was hugging, kissing, or cuddling with a partner (21.5%), and the most common behavior to decrease was sex with a main partner (36.7%). Household factors like job/income instability and having children over the age of 12 years were significantly associated with decreased affectionate and sexual partnered sexual behaviors; more frequent substance use was linked to significantly increased solo, partnered, and virtual sexual behaviors. Conclusions Understanding changes in sexual behaviors-as well as the factors that make changes more or less likely among adults around the world-are important to ensure adequate sexual health support development for future public health emergencies.

INTERNATIONAL JOURNAL OF SEXUAL HEALTH : OFFICIAL JOURNAL OF THE WORLD ASSOCIATION FOR SEXUAL HEALTH 2023; 35:139-151. [PMID: 38596767 PMCID: PMC10903576 DOI: 10.1080/19317611.2022.2163446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 11/22/2022] [Accepted: 12/21/2022] [Indexed: 04/11/2024]
Abstract
Objectives We examined changes in frequency of sexual behaviors, dyadic sexual desire, relationship satisfaction, and COVID-19 stress in Canadians across the pandemic, considering partner status. Methods Participants completed online questionnaires. Results Participants with live-in partners and single participants decreased in dyadic sexual behaviors. In August-September 2020, participants with live-in partners engaged in more dyadic sexual behaviors than single participants. In November 2021, all partnered participants engaged in more dyadic sexual behaviors than single participants. Decreases in COVID-19 stress were observed. Conclusions Findings suggest that despite decreases in COVID-19 stress, there may be long-lasting pandemic impacts on sexual behaviors.
