Sorry to hear this news, I hope they recover quickly. The fact is that Covid is still around and a very contagious disease, although not as serious for most people. At least for me, I've made some changes in my cruising behavior. I stay away from anything in the theatre where everyone is packed together, avoid long bus trips on excursions, fly in premium economy or first class and generally avoid crowds. I'm usually just happy to be cruising on my balcony and exploring ports on my own. Cruising is not the same for us as it was pre-Covid, we just look for different ways to enjoy ourselves.
