That does not equate to 9,637,930 individual Americans, adult and children. People are under quarantine, self or imposed. The quarantines are not lifted until a person, adult or child, tests negative. The same person can receive upward of two or more tests. The question is not the number of tests, but, the number of people tested and the their results. The statistics of results of testing is very important. Also, the type/brand of test used and quality of each one in accuracies of results. Accuracies equate to minimizing error.
I believe I posted an old professional article whereby testing error of VIRUS (RNA) was as high as 50 percent and scientists were frustrated with that high level of error. So when evaluating ERROR it may INITIALLY be high, but, demand for quality improvement must accompany such high errors. Scientists are very capable of quality improvement but it takes funding.
Even testing with high number of errors is still valuable in tracking trends, because their is still at least 50 percent accuracy. You have to start somewhere. When dealing with a deadly virus, 50 percent is better than zero percent. Funding does not have to be astronomical so much as sufficient. Thank you.
