I think one of the most useful set of data we could all use as a country is in what situations is the virus most likely to spread in significant amounts. Is it spread in retail situations Is it spread in larger gatherings Is it spread in nursing homes and long term care facilities Is it spread in apartment complexes Is it spread in hospitals Is it spread in open air parks and recreation places Is it spread in office buildings Etc.... I live in Cambria county in Pa, and I work as a pharmacist in a very busy Walmart. We have a total of 21 cases cumulatively in our county since mid March, and 0 cases in the zip code that my Walmart is located. Walmart has been open the entire time this has been going on and in the 6 weeks since this has become a major issue, I have not heard of one case or even one almost case involving any Walmart employee or customer. This leads me to believe that under proper precautions , the retail spread threat is relatively low. My bet is 50,000 people have wandered about that store over those 6 weeks, most without masks or gloves, Plenty of them high risk people, and still no cases at all. So we need to know what situations cause the most likely risk of significant spread, and I assume we can decipher most of this by contact tracing and questionnaires of positive cases of where they have been, etc. The point of the major shutdowns was to flatten the curve, and it appears that has been done in even the most hard hit areas. The point of the shutdown was not to reduce the new cases to 0. Therefore we need to know what situations are pretty darn safe so we can safely and successfully reopen as early as today in most places in this country.
