The fourth wave is here

By the numbers: On average, roughly 63,000 Americans per day were diagnosed with coronavirus infections over the past week. That’s a 17% increase from the week before, and echoes the rising caseloads of the pandemic’s second wave last summer.

Average daily caseloads increased over the past week in 25 states. The biggest spikes were in Michigan and New York.

Even as vaccinations continue to climb, new cases only declined in five states, mainly in the Southeast.

What we’re watching: Because so many seniors have been vaccinated — 73% have gotten at least one dose — this fourth wave is likely to be a lot less deadly than the previous ones.
