In the seven states hit hardest by the pandemic, more than 1 in every 500 residents have died from the coronavirus.

Why it matters: The staggering death toll speaks to America's failure to control the virus.

Details: In New Jersey, which has the highest death rate in the nation, 1 out of every 406 residents has died from the virus. In neighboring New York, 1 out of every 437 people has died.

• In Mississippi, 1 out of every 477 people has died. And in South Dakota, which was slammed in the fall, 1 of every 489 people has died.

States in the middle of the pack have seen a death rate of around 1 in 800 dead.

• California, which has generally suffered severe regional outbreaks that don't span the entire state, has a death rate of 1 in 899.
• Vermont had the lowest death rate, at 1 of every 3,436 residents.

The bottom line: Americans will keep dying as vaccinations ramp up, and more transmissible variants of the coronavirus could cause the outbreak to get worse before it gets better.

• Experts also say it's time to start preparing for the next pandemic — which could be deadlier.
