'The worst is behind us': COVID virus ebbs, lending hope to a nation lashed by disease

As vaccinations increase, the U.S. is seeing fewer cases, hospitalizations and deaths caused by COVID-19, suggesting America may have turned a corner in the pandemic.

The virus causing COVID-19 has begun to recede, just slightly, in the U.S. As experts predicted, the pandemic is operating on less of a light switch than a dimmer -- dialing back and forth in different pockets of the country. For once though, it seems, the nation’s pandemic dimmer is turning in the right direction. "I think we can confidently say the worst is behind us barring some crazy unforeseen variant that none of us are expecting to see," said Dr. Ashish K. Jha, dean of the Brown University School of Public Health. "We will not see the kind of suffering and death we have seen over the holidays. I think we are in much better shape heading forward,” Jha told ABC’s "Good Morning America" Friday.
