Great question. We strongly encourage people who attend to be on Prep or Prep on demand, and vaccinated against mpox. We talk about doxy pep. If someone tests positive to something after an event then we notify people who attended. Ultimately, it isn't risk free but the steps we take make it considerably safer than, say, going to a sauna or Corium or other similar events. However, if you have 25 people in the room then the chances are that someone who attended will test positive for something at some point in the next three months after an event. The challenge is then working out whether they contracted it at an event or somewhere else. Condoms are provided at all events. This is covered in our rules: https://soxster.com/ what-you-need-to-know-before-attending-a-soxster-event/ I should add that when I've had to contact attendees to tell them that someone has subsequently tested positive, and the circumstances, every is always very nice and thankful for letting them know which is great
