Track down everyone exposed to the virus. Test everyone. Isolate the sick and quarantine the exposed to stop the virus from spreading.

The hope was that a wealthy country like the United States would deploy those tried-and-true measures to rapidly contain the virus — like quickly dousing every ember from a campfire to keep it from erupting into a forest fire.

The U.S. has more COVID-19 testing than most. So why is it falling so short? The United States might have more COVID-19 testing capacity than any other country. So why have we seen laboratories overwhelmed and many patients again waiting a week or more for results? Allison Martell U.S.
