Either way, I think the paper you cited is worth reading. Many people think children are all safe to this, but they do still get infected. What is truly important to pay attention to is that infants are vulnerable to this virus. As the father of an infant, I am very worried.

As for Musk, he can say some dumb stuff like everyone. I just hope he follows through and helps manufacture ventilators with GM and other companies [0, 1]. We're going to be in for a lot of grief if we end up like Italy.
