Are those scare quotes or irony that isn't clear? Why link a CNBC article from 2020?

Here's a paper from last year: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9321237/

I don't put a huge amount of stock in much of the supposed science from June 2020. Also, as in my case, people definitely got mild symptoms of something, tested (if they could), got a negative result, and went on with life--when it's entirely possible they had it.
