The COVID-19 pandemic is not over. How will we know when it is?

“The startpoint of a pandemic is easier to pinpoint than the endpoint,” said Andrew Noymer, associate professor of [public] health at the University of California, Irvine. … “It’s going to be more like flu and less like measles,” Noymer added. “Because measles you get once and then you’re immune for the rest of your life. COVID shows a different pattern.” … “I think we will have more cycles, and cycles mean low points as well as high points,” Noymer said. “At some point, I do expect these cycles to be forced into a pattern like influenza.”
