The coronavirus is now the nation's deadliest pandemic, surpassing the death toll of the 1918 flu outbreak.
Six hundred seventy-five thousand people have died from COVID since the pandemic took hold of the country.
One hundred years ago, the population was about a third of what it is today, so the flu's death toll was more widely felt.
But the flu is still a deadly virus.
And COVID may be too, for years to come.
With the Delta variant pushing hospitals to their limits, doctors say don't push off getting your flu shot.
And this winter could be even more lethal.
