Over 30,000 mpox cases were reported during the 2022 mpox outbreak with many cases occurring among gay, bisexual and other men who have sex with men (MSM). Decreases in U.S. mpox cases were likely accelerated by a combination of vaccination and modifications to sexual behaviors associated with mpox virus transmission. We assessed reports of sexual behavior change among participants receiving mpox vaccination in Washington, DC.
During August to October 2022, 711 adults aged ≥18 years receiving mpox vaccination at two public health clinics in Washington, DC completed a self-administered questionnaire that asked whether sexual behaviors changed since learning about mpox. We calculated the frequency and percentages of participants reporting an increase, decrease, or no change in 4 of these behaviors by demographic, clinical, and behavioral characteristics with 95% confidence intervals.
Overall, between 46% and 61% of participants reported a decrease in sexual behaviors associated with mpox virus transmission, 39% to 54% reported no change in these behaviors, and <1% reported an increase. Approximately 61% reported decreases in one-time sexual encounters (95% confidence interval [CI], 56.8%-64.7%), 54.3% reduced numbers of sex partners (95% CI, 50.4%-58.0%), 53.4% decreased sex via a dating app or sex venue (95% CI, 49.7%-58.0%), and 45.6% reported less group sex (95% CI, 40.4%-50.9%). Reported decreases in these behaviors were higher for MSM than women; in non-Hispanic Black than non-Hispanic White participants; and in participants with human immunodeficiency virus than participants without human immunodeficiency virus.
Most participants receiving mpox vaccination reported decreasing sexual behaviors associated with mpox virus transmission, including groups disproportionately affected by the outbreak.
在 2022 年猴痘疫情期间，报告了超过 30000 例猴痘病例，其中许多病例发生在男同性恋、双性恋和其他与男性发生性关系的男性（MSM）中。美国猴痘病例的减少可能是疫苗接种和与猴痘病毒传播相关的性行为改变的综合作用。我们评估了在华盛顿特区接受猴痘疫苗接种的参与者报告的性行为变化。
在 2022 年 8 月至 10 月期间，华盛顿特区两家公共卫生诊所的 711 名年龄≥18 岁的成年人接种了猴痘疫苗，他们完成了一份自我管理的问卷，询问自了解猴痘以来，性行为是否发生了变化。我们按人口统计学、临床和行为特征计算了报告这些行为中 4 种行为增加、减少或没有变化的参与者的频率和百分比，置信区间为 95%。
总体而言，46%至 61%的参与者报告与猴痘病毒传播相关的性行为减少，39%至 54%的参与者报告这些行为没有变化，<1%的参与者报告增加。约 61%的参与者报告一次性性行为减少（95%置信区间[CI]，56.8%-64.7%），54.3%减少性伴侣数量（95%CI，50.4%-58.0%），53.4%减少通过约会应用程序或性场所发生性行为（95%CI，49.7%-58.0%），45.6%报告更少的群交（95%CI，40.4%-50.9%）。与女性相比，MSM 参与者报告的这些行为减少率更高；与非西班牙裔白人相比，非西班牙裔黑人参与者报告的这些行为减少率更高；与未感染人类免疫缺陷病毒的参与者相比，感染人类免疫缺陷病毒的参与者报告的这些行为减少率更高。
大多数接受猴痘疫苗接种的参与者报告减少了与猴痘病毒传播相关的性行为，包括受疫情影响不成比例的群体。
