I'm not sure that I could comment that they're at higher risk, but on the notion that it is only the elderly or only those who have comorbidities who are getting ill, I would say that might be the average. However, I've certainly seen lots of younger people, and some very young people who were previously healthy, who have developed severe disease. That's not the most common presentation at all, the most common risk group, but there are definitely so-called “host factors” in ourselves that might predispose beyond the typical risk factors.
