But it’s not over yet.
The vast majority of these cases – at least 2,672 – are the most contagious variant known as B.1.1.7, first detected in the United Kingdom. The variant was found in 46 states, Puerto Rico and Washington, DC.
“This strain is growing exponentially, it is increasing,” infectious disease specialist and epidemiologist, Dr. Celine Gounder, told CNN on Saturday. “So, we are probably now at the tipping point of another wave.”
Speaking about the dangers of this variant, Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, warned CNN on Friday: “that the virus is about to take off in the United States.”
The variants are a big reason why experts have repeatedly warned that now is the time to double the measures that work to stem the spread of the virus – and not to ease Covid-19’s restrictions.
“There are so many reasons why you don’t want to back down now,” said Dr. Anthony Fauci to CNN at the end of last week. “You want to plan that you will be able, within a reasonable time, to back off. But not at a time when we have variants circulating and when you have what looks like a plateau of declining cases.”
These states announced loosened restrictions last week
Despite warnings from health leaders, several state leaders announced that they were easing Covid-19 restrictions.
Meanwhile, Michigan Governor Gretchen Whitmer has revealed a series of eased restrictions, including expanded capacity for restaurants, retail, gyms, stadiums and other facilities.
And in Louisiana, Governor John Bel Edwards has also eased restrictions. Most companies – including restaurants and beauty salons – are now able to operate at 75% capacity, while religious services no longer have capacity limits.
Meanwhile, in California, all of the state’s amusement parks, including Disneyland, Magic Mountain and Universal Studios, along with sports and concert venues, will be able to reopen with limited capacity from April 1, the Secretary of Health and Services announced. Human Mark Ghaly on Friday.
“We feel that now is the right time to start reintroducing these activities in some way, and cautiously, slowly and steadily,” said Ghaly.
See how many Americans have been vaccinated
In their announcements for easing restrictions, several state leaders pointed to the growing light at the end of the tunnel and expressed optimism fueled by the increasing numbers of vaccinations.
But experts warned that the United States probably still has a few months to go before enough Americans are vaccinated to help suppress the spread of the virus. So far, less than 10% of the country’s population has been fully vaccinated.
Last week, new research offered reassuring news: there is now more evidence that variant B.1.1.7 poses little threat to vaccine effectiveness.
The research, published on Thursday, shows that while the variant may hide a little from the immune system, it is not enough to significantly diminish the value of vaccines – and does not threaten to reinfect people who have recovered from the previous dominant variant of the virus.
“These findings indicate that variant B.1.1.7 is unlikely to be a major concern for current vaccines or an increased risk of reinfection,” the researchers wrote in their report, published in the journal Cell Host and Microbe.
Receiving both doses in a timely manner is “encouraged for maximum effectiveness” in areas where the variant is circulating, the researchers said.
