Earlier this year, the Navajo Nation Reservation was a major hot spot for coronavirus cases. Now, it's seen a day without a single positive case. It's a turning point in its battle against the virus. Navajo Nation President Jonathan Nez attributes that to Navajo leaders and citizens heeding the advice of public health officials. "All we did as leaders and public health professionals is we accepted [the] recommendations from the CDC, NIH," Nez says.
