According to the CDC, the more contagious Covid variants are predominant in the United States

Washington — The highly infectious variant of the coronavirus, first identified in the United States, has become the most common new source of infection in the United States, the director of the US Centers for Disease Control and Prevention said Wednesday.Anxious developments occur when officials and scientists warn about potential 4th surge Of infectious diseases.

Federal health officials said In January B.1.1.7 variant,Began Soaring in the UK To December Since then, it has blamed Europe and has become a major source of coronavirus infection in the United States, with the potential for significant increases in cases and deaths.

At that time, new cases, hospitalizations and deaths were the highest ever. From that peak, all numbers fell until late February. According to the New York Times database.. After spending a few weeks on the plateau, new cases and hospitalizations are increasing again. As of Tuesday, the average number of new cases in the country has reached about 65,000 per day. Mainly concentrated in Michigan metropolitan areas Not only in the New York City area.It’s an increase 19 percent Compared to the figure two weeks ago.

CDC director Dr. Rochelle Walensky warned last week that he “felt a repetitive sensation.”Imminent ruin“Wednesday. 52 of the 64 jurisdictions of government agencies, including states, several major cities and territories, are currently reporting. Cases of these so-called “variants of concern” Includes B.1.1.7.

However, the number of deaths continues to decline. This may indicate that mass vaccination is beginning to protect older Americans and other highly vulnerable people.

“These trends show two clear truths,” said Dr. Warensky. “One is that the virus is still catching us, infecting people and endangering them. We need to stay vigilant. And second, we accelerate our vaccination efforts. You must continue to do so and take personal responsibility to get vaccinated if possible. “

B.1.1.7, the first variant of widespread attention, More contagious than 60 percent And 67% More Deadly According to the latest estimates, than the original form of coronavirus. The CDC is also tracking the epidemic of other variants, such as B.1.351, which was first discovered in South Africa, and P.1, which was first identified in Brazil.

The proportion of cases due to variants is clearly increasing. Lab test company Helix has been tracking the constant increase in B.1.1.7 since the beginning of the year. As of April 3 Estimated Variants make up 58.9 percent of all new tests.

The variety has been found to be the most prevalent in Minnesota, Florida, Colorado, California, Minnesota, and Massachusetts. According to the CDC Until recently, Variant rise Disguised somewhat by lower overall infection rates, some political leaders have relaxed restrictions on indoor dining, social distance, and other measures.

When the incident fell, the restless Americans returned to school to work, Against the warning Of some scientists.

Federal health officials are tracking reports of an increase in cases related to day care centers and youth sports, and hospitals are seeing an increasing number of young people in their 30s and 40s hospitalized for “severe illness.”

Due to the increasing frequency of B.1.1.7, it is difficult for scientists to say exactly how many current infection patterns are.

Dr. Adam Rolling, a virologist at the University of Michigan, said:

But he said people were losing caution when it was time to be more vigilant against more contagious variants. “I’m curious,” he said.

At the same time, the United States is now Vaccination of about 3 million people a day on average, And the state is in a hurry to qualify all adults. The CDC reported on Tuesday that approximately 108.3 million people had been vaccinated at least once with the Covid-19 vaccine, including approximately 64.4 million who were fully vaccinated. New Mexico, South Dakota, Rhode Island, and Alaska are the leaders, with approximately 25% of the total population fully vaccinated.

Scientists hope that vaccination will slow down a potential fourth surge.

on Tuesday, President Biden raises vaccination schedule By two weeks, call on the state to qualify all American adults by April 19. All states have already achieved or will achieve this goal after first requesting it to do so by May 1.

The B.1.1.7 variant first arrived in the United States last year. In February, a study analyzing 500,000 coronavirus tests Hundreds of genomes We predicted that this variant could become dominant in the country in a month.At that time, the CDC was having a hard time Sequence the new variant, It made it difficult to track them.

However, these efforts have improved significantly in recent weeks, primarily at $ 1.75 billion. Funding for Genome Sequencing In Stimulation package Mr. Biden signed the law last month. In contrast, the United Kingdom, which has a more centralized medical system, launched a highly facilitated sequencing program last year that allows it to track the spread of B.1.1.7 variants.

Dr. Carlos del Rio, a professor of medicine at Emory University and an infectious disease expert, said: University. In addition to spreading more efficiently, he said the B.1.1.7 strain appears to cause more serious illness, “it causes double pain to you.”

Perhaps even more troublesome is the emergence of pathogenicity P.1 variant In North America.First identified in Brazil, it has become the predominant variant in the country and has helped drive it. Hospital to the limit..In Canada, P.1 variant Appeared as a cluster in OntarioAfter that, we will close the Whistler Ski Resort in British Columbia.On Wednesday, the National Hockey League Vancouver Canucks said at least 21 players And four staff members were infected with the coronavirus.

In a statement, team doctor Jim Bobard said, “This is a clear reminder of how quickly the virus can spread, even among healthy and young athletes, and its serious consequences.” Said.
