A 4th COVID-19 Surge May Be Starting. How Bad Could It Get?

After more than two months of steep declines, coronavirus infections are on the rise again nationally — along with COVID-19 hospitalizations in many states.

In the past seven days, the U.S. reported slightly more than 65,000 new cases per day on average, a jump of 20% from two weeks earlier. Many states have seen even more dramatic growth, as high as 125% in Michigan, according to an NPR analysis of data from Johns Hopkins University.

And hospitalizations have risen for seven consecutive days in more than a dozen states, mostly in the Midwest and Northeast, according to the University of Minnesota’s COVID-19 Hospitalization Tracking Project.

These signs all point to the growing threat of another significant surge in COVID-19 cases, experts say.

But there’s cautious optimism that it’s not likely to be as devastating as the previous wave, which saw 200,000 or more confirmed cases a day on average for most of December and early January, according to data tracked by Johns Hopkins University.

“Thanks to the rapid rollout of vaccines, I don’t think we’ll have a surge that is anything like what we’ve seen before,” says Jennifer Nuzzo, an epidemiologist and senior scholar at the Johns Hopkins Center for Health Security. “Still, any additional deaths at this point are tragedies, given that we have on hand vaccines that could have prevented them.”

What’s driving the growth in infections?

Another surge is inevitable, says epidemiologist Bill Hanage of the Harvard T.H. Chan School of Public Health. But he adds that “it might not be national, not all at the same time, and the consequences will vary depending on how many people are vaccinated when it kicks off.”

Indeed, the rise in cases so far isn’t consistent across the country. The Midwest has seen a 58% increase in new cases over the past 14 days, while the number of cases in the Northeast has climbed by 30%. Cases in the West rose by 5% and the South shows a slight decline.

Overall, 33 states and the District of Columbia have rising cases with seven states (plus Puerto Rico) growing by more than 50%.

A host of factors are fueling the resurgence. States have been loosening restrictions, while pandemic fatigue has led to less vigilance about precautions such as mask-wearing, social distancing and hand-washing.

Perhaps the biggest unknown is how the rapid spread of one particular coronavirus strain may play out.

The highly contagious B.1.1.7 variant represents a growing share of cases in the U.S. and is likely driving the current increase, notes Hanage. The strain, which emerged in the U.K., is up to 50% more infectious, and new research suggests it’s more likely to result in serious illness and death as well.

Hospitalizations are another sign of how the surge is ramping up. The growth over the past week or so is the first time since the winter surge that hospitalizations appear to be rising: 10 states experienced spikes of 10% or more; four states — Michigan, South Dakota, Connecticut and Maryland — saw rises of about 15% or more, according to the University of Minnesota’s COVID-19 Hospitalization Tracking Project.

“A matter of choice”

For now, there’s still plenty of reason for hope. The vaccine rollout is happening fast, though unevenly. So far, about 17% of U.S. adults are fully vaccinated.

And the vaccines appear to be effective at preventing severe illness and death from all the strains currently circulating, including the B.1.1.7 variant, Hanage told NPR’s All Things Considered. So it’s a race to get people vaccinated before the fast-spreading variant can take over.

There are two more positive factors to consider: the warming weather and existing immunity from previous infections, says Natalie Dean, a biostatistician at the University of Florida.

The fact that a lot of people have been infected naturally — during the last surge and even earlier — “will help take the edge off a bit of what potentially can happen in the future,” she explains. “And the fact that we’re moving out of the winter months into the spring, all of those things are working to our advantage.”

Still, Harvard epidemiologist Hanage notes that it’s important to pay attention to high-risk groups who may not be getting vaccinated as quickly.

“It doesn’t take a large number of infections in the most vulnerable groups to cause serious problems,” he told NPR.

Researchers NPR spoke to all cautioned that public policy and Americans’ behavior can still make a huge difference in how bad this next surge will be.

Alessandro Vespignani, a disease modeler at Northeastern University in Boston, warns that relaxing measures like social distancing now could turn this into a bigger surge. Instead, he says, we need more time for the vaccination campaign to roll out.
