I have wondered about it too. Two of my female first cousins, both in their early 80s,have traveled frequently during covid19. Several vacations at beaches on the Atlantic Ocean in Northern New England. Other trips by air to visit a sick woman who was a friend of sorts of their dad. About six weeks ago, their younger brother was told he had panchriatic cancer. I agree with their younger brother
He and has wife had to insist they not visit
