The number of people diagnosed with coronavirus is going in the wrong direction. Wednesday marked the single highest number of new cases yet. But an even more disturbing number is coming from CDC director Dr. Robert Redfield. He says, “Our best estimate right now is that for every case that’s reported, there actually are 10 other infections.”

NBC writes:

The estimate comes from looking at blood samples across the country for the presence of antibodies to the virus. For every confirmed case of COVID-19, 10 more people had antibodies, Redfield said.

Currently, there are 2.3 million COVID-19 cases reported in the U.S. The CDC’s new estimate pushes the actual number of coronavirus cases up to at least 23 million.
