I think this nicely sums up the article's point:
"It's the civic and moral duty of every person, everywhere, to take part in the global effort to reduce this threat to humanity. To postpone any movement or travel that are not vitally essential, and to spread the disease as little as possible. Have your fun in June, July and August when this—hopefully—is over. Stay safe. Good luck."
In other words, it's not "this is young people's fault" but "just because you are young doesn't mean you should ignore this"
