As with everything pandemic, here’s an opinion you may agree or disagree with. I’m looking forward to the time when covid-19 group-think will be as “common sense” as all the many things we learned as we first left the nest and learned to fly, and public health will once again be something we take for granted:

“The high rate of false negatives means that testing provides the most protection when it’s deployed at the population level. At the group level, it’s only a weak, adjunct tactic to other precautions. And at the individual level, it’s borderline useless.” (

On the other hand, public health has always been better for some people than others. And a lot of our “common sense” up to now has really been quiet acceptance of preventable disease – illness and death statistics that we might know about and quote, but which we may have lost interest in trying to make better.
