Anecdotally people have been saying that testing positive has taken longer and longer into the illness with each omicron variant for a long time now, but this is the first time I've seen someone say it in an article.
I check through the COVIDPositive reddit nearly every day to get an idea of the real life stories and I can't even tell you how many "I tested negative when I started feeling bad, went about my daily life and then tested positive a week later. I feel so bad!" stories I've read this year.
Masking, ventilation, filtration and, as the article stated, steering clear of people with symptoms are your only real options at this point and the last one is, unfortunately, out of your control in public because people insist on being *everywhere* while sick. Honestly, it wasn't OK in 2019 and it's not OK now people!
