Seven Months Later, What We Know and Don't Know About COVID-19

 It's been a bit more than seven months since the onset of the COVID-19 pandemic, and in that time, researchers have found out a lot about the disease. There's also a lot we still don't know. (I'll leave the issue of information/disinformation) out of this for now). 

STAT News (produced by the Boston Globe) has published an overview article about the pandemic that summarizes out current knowledge, and lack of it, about the disease. One of the authors is Helen Branswell, so I think you can count on the information in the article being accurate. 

I'll list some of the topics. First what we know:

• Covid and kids: it's complicated.
• There are safer settings and more dangerous settings.
• People can test positive for a long time after they recover. It doesn’t matter.
• After the storm, there are often lingering effects.
• 'Long haulers' don't feel like they've recovered.

And what we don't know:

• How much virus does it take to get infected? 
• People seem to be protected from reinfection, but for how long? 
• It’s not clear why some people get really sick, and some don’t.

There's much more in the article.
