To add, it's a bit concerning seeing that the military has put a ban on enlisting those who have tested positive, were hospitalized, and recovered without the ability to be waivered. (I mentioned this in another post about a week ago when it was reported).

Then just a few days ago, it was reported that ~13 sailors who were positive, recovered, isolated, then tested negative two times in a row, retested positive and some were showing symptoms again.

It could be due to inaccuracies in testing, but given that some showed symptoms again and tested positive, it seems possible that they either didn't develop an immunity and caught it again, or this could be a chronic illness.

The reason for banning enlistees being a vague "as a precaution", is a little suspicious. Who knows though. Regardless, it's a something to keep an eye on as it develops.

It's unfortunate that the guy who highlighted the problems on the Roosevelt was also fired.

The literature has a lot of case reports, but nothing substantial last time I checked. This makes a non-sensationalistic look at those issues (and more importantly, how much they occur) difficult.
