It is. What's worse, in a way, is that evidently the course of the disease is so unpredictable. I saw a video featuring a doctor from Louisiana. He was perhaps in his late 50s or early 60s, He said at first it was like the flu. He had a low fever, body aches, a dry cough, but he didn't feel all that bad, and so stayed home waiting for it to go away.
And then after five days, he suddenly got a lot sicker. Had breathing problems, and I think was taken to the hospital. He said it was the sickest he'd ever felt. Finally, 12 days after it started, he began to feel it was almost over.
But of course other people, like Rand Paul, are asymptomatic.
