How have I NOT heard of world class performers getting covid and maybe also ocasionally getting hospitalized for covid? And having long covid symptoms where they cant sing and dance like they used to?

I have long covid from the single time I've ever had covid. I'm not a singer or a dancer, but if I got all the right training, I think my long covid symptoms limits my ability to physically endure performing a concert. These superstars are constantly sharing air with thousands of people in single nights. In airports, at shows, dance practice, parties, meetings. Are they hiding the news? Do they just view it as the flu and don't think it's worth reporting? What's happening?
