Remember that death isn't the only bad outcome: just because you survive doesn't mean you're out of the woods, unfortunately. I'm afraid "Long COVID" is a thing, for adults and children.
"Evidence from the first study of long covid in children suggests that more than half of children aged between 6 and 16 years old who contract the virus have at least one symptom lasting more than 120 days, with 42.6 per cent impaired by these symptoms during daily activities. "
There are folks that are still debilitated, almost a year after their "recovery". We don't know if/when their sequelae will disappear. Time will tell.
