New York, Michigan, Florida, Pennsylvania and New Jersey recorded more than 196,400 of the 453,360 cases reported in the country last week, according to data available Wednesday morning.
These states account for only 22% of the US population, according to estimates from the US Census Bureau.
“Based on our most recent estimates of CDC surveillance, the B.1.1.7 variant is now the most common lineage in circulation in the United States,” Walensky said during the team’s briefing. Covid-19 intervention from the White House.
With the addition of more transmissible variants, outbreaks like those in Michigan may soon be seen more widely, even as vaccination rates have increased nationwide, said epidemiologist Dr Michael Osterholm.
“I wish we had another three or four months before this B.1.1.7 variant push started to happen,” Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, said Tuesday.
The surge in variants in some states like Michigan should prompt the federal government to consider changing the way it allocates vaccines, Dr. Ashish Jha, dean of the Brown School of Public Health, told CNN on Wednesday.
“So the federal strategy must be to move more vaccines to places like Michigan that are booming so they can use more vaccines to stop this surge and save lives,” he said.
The CDC says more than 16,200 cases of the B.1.1.7 variant have been confirmed in surveillance testing in the United States and that B.1.1.7 has been found in every state. This number does not represent the total number of such cases circulating in the United States, but only those that were discovered by analyzing samples.
CDC Director: Decreasing number of daily deaths may be ‘an impact of vaccination’
While cases have recently risen or peaked, the number of daily deaths from Covid-19 has declined.
The United States has recorded an average of 774 Covid-19 deaths per day over the past week, down 22% from the previous week’s average, according to data from Johns Hopkins.
This is even lower since the first day of March, when the average was around 2,000 deaths per day.
At Wednesday’s briefing, Walensky attributed the declining numbers to vaccinations.
“I am really encouraged by this decrease in the number of deaths which I believe is an impact of immunization, especially immunization of our elderly communities,” Walensky said.
But, she added, the current case count is “far too high to think we’ve won this race.”
Half of American adults may have had their first injection on weekends, White House says
By the end of the weekend, the United States will approach nearly half of all adults having their first vaccine for Covid-19, a White House official said.
But vaccine advances don’t mean the country is done with the pandemic, a Biden administration adviser said on Tuesday.
“We have to remember that there are over 100 million adults who still have not been vaccinated,” Andy Slavitt, White House senior advisor on the response to Covid-19, told Chris Cuomo of CNN. “They aren’t here yet, and you don’t win the war until you bring everyone with you.”
Some states are withdrawing hidden mandates and opening up capacity for companies. But Fauci said on Tuesday that giving up preventative measures when the majority of Americans are still unvaccinated is a mistake.
“It is premature to declare a victory,” said Fauci, director of the National Institute of Allergy and Infectious Diseases. “We have to keep going and hang on a little longer by continuing the public health measures.”
The United States always has the tools to stay the course even if the public is tired, Slavitt said. Opening up accessibility to vaccines and focusing on certain groups, as the US has done to give at least one injection to 80% of teachers and school staff amid calls to reopen the school, can help the country continue to fight Covid-19, Slavitt said.
Correction: An earlier version of this story and the title of the story overestimated the percentage of American adults who will be vaccinated by the end of the weekend. The White House clarified that the United States would approach having nearly half of all adults with their first coronavirus vaccine by this weekend.
