It's not faux covid
People are getting Covid and it's wiping them out. I work in a school so we're lucky enough to still have the odd box of LFTs knocking around and what I've noticed is people aren't testing positive until a good few days after feeling at their worst throughout the illness. So, what you get are people feeling rough, testing negative and then presuming they don't have covid.
Then there's the people who don't have any LFTs and don't really want to pay for one, so never know if it's covid or not.
And on top of that there's a pretty mean flu virus going around (lots of chest infections and laryngitis type illnesses). Flu isn't the same as covid - see the first few pages of this thread for a reminder of how they're different
