Just weeks after the coronavirus forced businesses and public spaces across the U.S. to close, more than half of the states have begun the reopening process in hopes of offsetting economic turmoil. Meanwhile, public health officials warn of a resurgence of the virus if social distancing measures are ended too quickly. Dr. Tom Inglesby, director of Center for Health Security of the Johns Hopkins Bloomberg School of Public Health, is a leader in the field of public health preparedness and pandemics. He joins CBS News' Dr. Jon LaPook to discuss what it will take to reopen our country, what precautions will be necessary, the risks of a second wave, and lessons from other countries.
