Really sorry to hear this happened. Requiring Covid testing, either rapid testing at the door which is not very expensive and is quite easy (I’ve been to a few events here in Israel where rapid tests were available at the door), and/or PCR tests within 24-48 hours of an event, can help prevent the spread. In-person events are awesome, so rather than canceling them altogether, might as well use the tools available to us to help keep people safe, even if they’re a bit inconvenient. Getting Covid is more inconvenient, and even dangerous for many people.
