The only problem with percent positive it’s not a random sample. If I was randomly selecting 1,000 people every day from the population and testing them then that would be a stronger indicator of what percent of the population is infected and if that percent was dropping it would be a really good sign. Similar to the random testing done in NY for anti-bodies. As testing ramps up you would naturally expect a decrease in percent positive since with limited testing only the ill were allowed to be tested in a lot of cases. Now with widespread testing we should be seeing a much lower positive percentage as family members and people who had casual contact with someone can now be tested too as well as potentially the general public without as many limits. With full contact tracing ramped up we should see an even lower positive percentage as many more people get tested with no actual symptoms.That’s why states look at the positivity rate. The number of tests vary each day. Orange County will give both numbers when they do an update at their briefings. I find that very helpful to see if the percentage of positive tests is going up. So far it’s been decreasing. But we need to watch this carefully in the coming weeks with more people out of their homes.
