Of course there is not going to be 100% protection from a virus, but from the beginning, some have claimed models and the ability to predict spread and infection and death, all the while ignoring far more variables than they ever considered in their predictions. Human behavior has to be modeled and they cant get that right.
This is a highly contagious flu, when it comes down to it. We have all gotten the flu. We mostly recover from the flu. Some folks with compromised immune systems or the elderly have a tougher time. Some die.
We have turned our society on its head to fight off something that can not be completely eliminated, and must be worked through. The social distancing is touted as the best answer and its reasonable and it has broad support without imposing dictates. Shuttering businesses does not have support anymore. Voluntarily wearing masks in certain situations makes sense for certain people. Mandated wearing of masks does not have support and is being used as a divisive issue by too many. If you are one who wants others to wear masks, find ways to adapt and assume everyone does not agree with you. Dont blame others for your fears or disabilities.
We’re past 100% on anything. A mask may be of limited value in a hot spot. That’s all.
