The research, published in BMJ Open, found that men who are gay, bisexual or who have sex with men (GBMSM) had a better understanding of mpox, its symptoms and risks, and were significantly more likely than the general population to intend to engage in most protective behaviours, except for self-isolation. Researchers suggest this demonstrates the effectiveness of targeted messaging from community-based organisations and charities to raise awareness of mpox in the most affected populations.

Implementing protective behaviours including self-isolation, contact tracing and vaccination uptake were a key aspect of the public health response to the COVID-19 pandemic, with uptake varying within the general population throughout the course of the pandemic. With the mpox outbreak of 2022 most significantly affecting the GBMSM population, community outreach and government messaging specifically targeted this group, placing a distinct focus on promoting understanding and protective behaviours, in contrast to attempting to engage with the whole population at once, as was the case during the COVID-19 pandemic.

Researchers sampled 5164 people, including those specifically recruited through Grindr and Meta (Instagram and Facebook) as well as via market research organisations. Respondents completed an online, anonymous survey. Those surveyed were asked about their intentions to self-isolate, seek medical help, stop all sexual contact, share details of recent sexual contacts and accept vaccination as well as their understanding and beliefs about mpox, and detailed demographic data.

Researchers found that responses and demographic details differed by sample, with respondents from Grindr and Meta more likely to be working, highly educated, and have less financial hardship. They were also more likely to intend to immediately seek help and completely stop sexual behaviour if they developed mpox symptoms and intend to be vaccinated. Broadly, the GBMSM sample showed a significantly greater understanding of the disease and how it spreads, compared with the general population, and a stronger willingness to enact protective behaviours, reflecting the targeted public health efforts and engagement with this group.

The general population results show a more significant skew relating to financial security and gender when considering protective actions. Generally speaking, women, older people, and those who were more financially secure showed a stronger intention to carry out protective behaviours such as self-isolation if they were contacted by public health officials and told that they needed to self-isolate. This suggests that providing financial support to affected groups may help enable them to engage in challenging behaviours such as self-isolating for extended periods of time.

Overall, education, targeted communication and financial stability appear to be the most effective elements encouraging protective behaviour in the wider community. Avoiding stigmatising the disease or a particular section of society would be beneficial in encouraging uptake of protective actions and vaccination.
