I keep hearing rumblings about test kits not being where they need to be, but nothing in the news. It would be so hard to make a clinical diagnosis of COVID-19 when the chief complaints are "Fever, cough, shortness of breath". Is that the common cold or is this SARS-CoV-2? Giving a massive diagnosis like and being wrong is bad.
