Dr Ruth's COVID Brief for 7/6/24

Here's a rare and very succinct warning from Dr Ruth Ann Crystal today, and I hope people will take this seriously:

"I wasn't going to post this week, but COVID is surging, so I wanted to share some data without a research summary. SARS-CoV-2 levels are quite high in many places in the United States now. I would definitely recommend wearing a good fitting N95 or KN95 mask on airplane flights and public transportation now. 

"Have a good rest of your weekend,

"Ruth Ann Crystal MD"
