I started thinking about this after the Santa Clara Study and the Sweden experiment.
https://www.cnn.com/2020/04/17/health/santa-clara-coronavirus-infections-study/index.html
Chicken-Pox, Mumps, Measles are all very dangerous to adults. It was why, before vaccines, it was important to be infected as children. So we would be protected for our lives.
Is SARS CoV-2 just another one of these? It does not seem to blow up in most children to a full on COVID-19 disease. Adults who contract it, especially the elderly, seem to be affected the worst, the older you get.
If it is as "wide spread" as the Santa Clara study indicates, maybe it is a "chicken pox" where most people get it, and just become immune without many/any symptoms.
Thoughts?
