One Country, Different Reactions- How did the Gay Community in Israel Respond to the New Mpox Threat?

Mpox affected mainly men who have sex with men (MSM). This study aimed to assess MSM’s response to the threat, and compare MSM living in central Israel vs. its periphery. Data were collected by anonymous electronic surveys between September and October 2022 through a geospatial application (“Grindr”). Of the 665 MSM participants, 221 (33.2%) were vaccinated against mpox. In the multivariate analysis, living in central Israel, being in steady relationships, HIV infection, PrEP use, noticing suspicious skin lesions, and changing sexual behavior predicted vaccination. Of all participants, 317 (47.6%) changed their sexual behavior. In the multivariate analysis, living in central Israel, engaging in risky sexual behavior and being vaccinated against mpox predicted sexual behavior change. Of the 444 participants who were not vaccinated, 245 (55.1%) lived in peripheral regions of Israel. Those who lived in the periphery were less likely to get vaccinated or change their sexual behavior compared with MSM who lived in central Israel. Although the study was limited in size and the study population was relatively homogeneous, MSM perceived mpox as a potential threat on health, and almost 50% changed their sexual behavior and nearly one-third were vaccinated against mpox. The trend was mainly observed in MSM who were at high risk to acquire mpox and those who lived in central Israel.
