Doctor urges Americans to cancel holiday travel as COVID-19 spreads

The U.S. has recorded its single worst daily death toll since the beginning of the pandemic, and health officials say the number of infections and deaths will only continue to rise, in part due to the delayed effects of Thanksgiving travel. CBS News correspondent David Begnaud reports on new safety measures being implemented by local officials, and Dr. Shoshana Ungerleider, an internal medicine physician at California Medical Center, joined CBSN to discuss what action needs to be taken to mitigate spread, and what obstacles health care workers are facing.
