Doctor discusses NYC schools suspending in-person learning as COVID rate rises

New York City public schools have suspended in-person learning because the coronavirus positivity rate surpassed 3% citywide. That's despite the fact that the positivity rate within schools is at just 0.23%, and as restaurants and bars remain open. Dr. Eric Cioe-Pena of Northwell Health joined CBSN to discuss why that 3% rate is arbitrary, and what states in the Midwest -- where rates are even higher -- need to do to stop the spread of the virus.
