Unless you’re testing weekly, which would be a huge waste of resources, you won’t know if you’ve had it for sure unless you got symptoms, most people are asymptomatic. Marchlove, you are of course right with regards to how society has accepted that viruses will affect the elderly or sick much worse and that is something about life we must and have accepted until recently. The difference with covid is the way it spreads like a cold but is as potent as other flu strains. It’s the speed of spread that caught us out. I’ve had much worse flu experiences, even when in my twenties, than the two times I’ve had covid. More could be done by helping people stay healthy in the first place, preventative healthcare is not a top priority for any government and it ought to be. My husband was overweight when the covid pandemic started and it was the wake-up call he needed. He joined our child and I with our exercise routines and is now really fit and is a very healthy weight and his bloodwork, cholesterol etc is excellent. More people should of taken the opportunity of lockdown to focus on their health. Taking a jab and wearing a mask are easy things to do, but being a healthy weight is way more important IMO.
