It’s not apparent that everyone who is exposed develops symptoms, As random testing becomes more prevalent, we will be able to discern the true fatality rate.
A few points- the sampling in California, in Santa Clara, was not of people showing symptoms or with a high index of suspicion of having contracted Covid , but of people solicited on Facebook to participate. I’m about how you could infer that participants are not representative to random sampling.
Also, I believe that the author mentioned the fact that quarantining the healthy has actually been tried in the past, and then mentioned the plague. How did that work out? I could go on, the author gratuitously uses ad hominems about Dr. Erikson’s credentials and intelligence, these are not germane to the discussion. The main point of Erikson’s presentation is that it is time to start to use a more adaptive approach to this virus as we gather more data. The object was/is to flatten the curve so as to not overwhelm the health care system. The dire predictions have not materialized, considering all other negative societal impacts, we need to start returning , cautiously, to normal.
