 We've made a lot of progress in the last year, but it still feels pretty random in terms of who gets it. We have certain things that are fairly well established now. If you've had a really bad case, for example, hospitalized or had to go to the ER, you're more likely to get it. If you're older, you're more likely to get it. If you're female, you're more likely to get at least some manifestations of long COVID. And the list just goes on.
