Dr. Michael Osterholm: 'We'll see a tremendous number of ill people’ without a new lockdown

Dr. Michael Osterholm, Director of the Center for Infectious Disease Research Policy, is calling for a new shutdown to control the spread of the virus. He tells Andrea Mitchell that the lockdowns in the spring helped to slow down transmission, but we “never got our numbers down to a low level where we could fight with traditional public health tools.” He does say that elementary schools can reopen safely, but only “in communities that have low levels of transmission.”
