Sorry you're still sick?

Are you sure it's the same bug? Did you test positive again? Or is this a case of having residual effects from the first bout?
I read the other day that the U.S. has had 5 million people test positive (that's about one in 70 people) but it is generally accepted that at least 10 times that many people have had it but weren't tested (this has generally been borne out by antibody tests). This means about 1 in 7 Americans has already had the virus. The fact that so many people have few or no symptoms is being pegged to T cells, which may recognize this coronavirus because of past experience with other related coronaviruses.
The fact that our case count is way up but our death rate is way down is very good news. There has been a lot of fear mongering about the "new wave" of cases being a harbinger of doom, and while some areas did see a small spike in deaths, it has been nowhere close to what was happening back in March and April. We can't begin to know how many cases occurred early in the year because tests were scarce and reserved for those with severe symptoms.
I have high hopes that like other common cold viruses, once people have had this one, even if their immunity eventually wears off, their T cells will remember it and be much better at fighting it off in subsequent encounters and symptoms will be fewer, shorter-lived, and far less serious.
