That part I would disagree with.Myself and every person I know that have had it have completely ignored safety precautions after having it.I was far more cautious prior to catching it than after.
I guess it varies by individual. Studies have shown that people who were hospitalized with COVID (which accounts for approximately 12% of the tested cases in western nations (higher in early 2020) prior the vaccine being available -- now down below 6%) tend to be more cautious after getting out of the hospital. Similarly studies have shown people with serious long COVID symptoms tend to be more cautious.
