It seems that the CDC's logic is that reducing the quarantine will encourage people 1) to get tested, since 5 days of quarantine isn't as bad as 10 days and 2) to actually quarantine if they are exposed or positive. But no one is going to wear a mask for those 5 days after quarantine. You're either contagious or you're not. If you and/or others believe you're contagious, you're going to isolate. If you don't believe it, you're not going to wear a mask. No one is going to go around saying "yeah, I might still have COVID so I thought I'll still hang out with you, but I'll just wear a mask". Yeah right. And sadly, the CDC don't appear to be offering any advice or information about how long one is actually contagious, which is the information people really need to make safe and responsible decisons. Nor do they appear to be encouraging more rapid at home testing, which is really what needs to happen to start managing this virus. I spent the entire day today calling around for any kind of rapid tests anywhere in Ohio after someone from our Christmas Eve gathering fell sick. They're sold out everywhere. Was finally able to get some tests when a shipment came in to the county health department, but they were gone in a couple of hours. Meanwhile, I think Joe Biden is asleep. Why doesn't he issue an executive order and/or activate the Defense Production Act to get rapid tests to Americans now? He's had plenty of time to prepare.
