Which health experts? Why do they fear this?
"Alina Alonso, the health department director of Palm Beach County, reportedly told county commissioners on Tuesday that the long-term consequences of coronavirus in children are unknown."
That doesn't sound like fear to me, and in some respects the article comes off on me as though the author is attempting to elicit fear where there should be none. I am not a parent myself, but if there's one thing I know about them it's that they tend to be VERY fearful when it comes to their children's safety. If the author is deliberately toying with that then the ought to be ashamed.
