In recent weeks, U.S. coronavirus case data — long a closely-watched barometer of the pandemic’s severity — has sent some encouraging signals: The rate of newly recorded infections is plummeting from coast to coast and the worst surge yet is finally relenting.
But scientists are split on why, exactly, it is happening. Some point to the quickening pace of coronavirus vaccine administration, some say it’s because of the natural seasonal ebb of respiratory viruses and others chalk it up to social distancing measures.
And every explanation is appended with two significant caveats: The country is still in a bad place … and recent progress could still be imperiled, either by new fast-spreading virus variants or by relaxed social distancing measures.
The rolling daily average of new infections in the United States hit its all-time high of 248,200 on Jan. 12…. Since then, the number has dropped every day, hitting 91,000 on Sunday, its lowest level since November.…
“Two [factors] are driving down transmission,” [a February 12 briefing by the University of Washington’s Institute for Health Metrics and Evaluation] says. “1) the continued scale-up of vaccination helped by the fraction of adults willing to accept the vaccine reaching 71 percent, and 2) declining seasonality, which will contribute to declining transmission potential from now until August.”
The model predicts 152,000 more covid-19 deaths by June 1, but projects that the vaccine rollout will save 114,000 lives.
In the past week, the country collectively administered 1.62 million vaccine doses per day…. It was the best week yet for the shots, topping even President Biden’s lofty goal of 1.5 million vaccinations per day.
Nearly 40 million people have received at least their first dose of a coronavirus vaccine, about 12 percent of the U.S. population. Experts have said that 70 percent to 90 percent of people need to have immunity, either through vaccination or prior infection, to quash the pandemic.
Get vaccinated as soon as possible!
