Tl;dr version: Covid is a vascular disease that stays in the bloodstream potentially coming back to cause more harm later - we don't know longterm how it will affect people. (Chicken pox becomes shingles decades later.) It's getting worse and will continue to get worse the longer we ignore it and allow it to spread and mutate into more evasive variants that no longer respond to our current meds, and it can cause dangerous brain effects that go unnoticed. We need to wear masks until we have really clean air in every public building evidenced with CO2 monitors on display showing 700ppm or less. (Actually we need to wear masks until we have eradicated the virus, but that might never happen, so it's nice to have an endpoint to rally behind.)
So one of my friends/colleagues tests before they go to see their elderly mother, which was the only reason they found out they had a new covid infection. They stayed at home and said they have actually felt great for the first ten days of their infection, except every single one of their messages has multiple typos and disjointed sentences, when they're normally very precise. And the messages themselves are full of inaccuracies and contradictions and misrememberings.Hey ho. At least they feel great.Just imagine if that was your pilot or surgeon, or a truck driver, radiologist, gas engineer, politician, cardiologist, air traffic controller, judge, paramedic, sewage handler, biochemist, nuclear plant engineer, rail engineer, pharmacist, armed response unit...Feeling great and not realising they aren't great is not a good scenario for restricting spread of the disease.
