The Unsung Heroes of Public Health

With the U.S. public health system front-and-center (think: COVID and Monkeypox), "Sunday Morning" explored what the public health system actually does. Michelle Williams, dean of faculty at the Harvard T.H. Chan School of Public Health said the estimated 270,000 public health workers in this country are unsung heroes who aren't valued enough because the public takes their contributions for granted. "When public health works, nothing bad happens. So, you don't notice that that child that had a spill on the bicycle got up and is just fine because they're wearing a helmet," she said.
