Scientists worry virus variant may push up COVID-19 cases in US

With coronavirus outbreaks rising in parts of Europe and Asia, scientists worry that an out-of-contagion version of the micron variant could soon increase the incidence in the United States. Experts are also watching for another mutant: a rare delta-micron hybrid that they say is not a big threat right now, but shows how smart the coronavirus can be. The U.S. is likely to see an increase in cases caused by Omicron’s BA.2 offspring starting in the coming weeks, according to Dr. “It is inevitable that we will see a BA.2 wave here,” said Eric Topol, head of the Scripps Research Translational Institute. One reason; After about two months of falling COVID-19 cases, pandemic restrictions have been lifted in the US Many people take off their masks and return indoors to restaurants and theaters. Dr. Anthony Fauci, the US government’s top infectious disease specialist, told ABC “This Week” at the weekend that he also believed the US was likely to face a “rise” similar to that in Europe, particularly in the UK. where BA.2 is the dominant strain. He said he did not think it would be a “wave”. The United Kingdom “was in the same situation as we are now,” Fauci said. “They have BA.2. They have relaxation of certain restrictions such as indoor coverage and there is a reduction in immunity” from vaccines and previous infections. In the US, the latest data from the Centers for Disease Control and Prevention show the overall COVID- 19 cases are declining. But the share caused by BA.2 has increased significantly. the variant accounted for about 35% of the new infections reported last week. To the northeast, it was about half. Keri Althoff, a researcher at the Johns Hopkins Bloomberg School of Public Health, warned that CDC cases underestimate the real numbers because some people are no longer tested and others take tests at home and do not report results. He also said that not every sample is genetically determined to determine the variant. It’s clear, he said, “BA.2 is coming on the scene.” One reason the variant has gained ground, scientists say, is that it is about 30% more contagious than the original micron. In rare cases, research shows that people can get sick even if they already have a micron infection – although it does not appear to cause a more serious illness. Vaccines are equally effective against both types of microns, but unprecedented infections are possible. Experts also point out that vaccination rates are lower in the US than in the UK. About 74% of people aged 12 and over are fully vaccinated in the US, compared with 86% in the UK. country compared to peers “, said Topol. However, not all experts are equally concerned about the increase in BA-related cases in the US.2. Dr James Musser, head of genomic medicine and infectious diseases at the Houston Methodist, said the variant has so far caused only about 1% to 3% of cases in his medical system. The cases there usually follow closely what is happening in the UK. He called BA.2 “something we watch”, but said, “I’m not losing my sleep” because of it. This is how many scientists see the other variant that some in the public call “deltacron”, a hybrid that contains genetic information from both the delta and the micron. Earlier this month, the World Health Organization’s Maria Van Kerkhove said the hybrid had been detected at “very low levels” in France and the Netherlands and Denmark. Both recent studies, which have not yet been peer-reviewed, indicate a small number of cases in the US. Many remain unknown about the hybrid. There is no evidence that it causes a more serious illness and it does not seem to infect many people. CDC researchers identified nine samples, seven from the Mid-Atlantic region, in a study released Monday that has not yet been peer-reviewed. Topol, who did not take part in the investigation, said there was no indication that it could spread. It is common for coronaviruses to mix up parts of genes, said Dr. Stuart Campbell Ray, an infectious disease specialist at Johns Hopkins University. With two variants circulating at the same time, people can catch duplicate infections and a “offspring virus” could appear. “Given the virus’ ability to give birth to new mutants – and the rise of BA.2 – experts say people should be vaccinated if they are not and keep their masks handy.” Be careful, “Topol said. “It’s not over.” The AP is solely responsible for all content.

With coronavirus outbreaks rising in parts of Europe and Asia, scientists worry that an out-of-contagion version of the micron variant could soon increase the incidence in the United States.

Experts are also watching for another mutant: a rare delta-micron hybrid that they say is not a big threat right now, but shows how smart the coronavirus can be.

The U.S. is likely to see an increase in cases caused by the offspring of the micron BA.2 starting in the coming weeks, according to Dr. Eric Topol, head of the Scripps Translation Research Institute.

“It is inevitable to see a BA.2 wave here,” he said.

One reason? After about two months of falling COVID-19 cases, pandemic restrictions have been lifted in the US Many people take off their masks and return indoors to restaurants and theaters.

Dr. Anthony Fauci, the US government’s top infectious disease specialist, told ABC “This Week” at the weekend that he also believed the US was likely to face a “rise” similar to that in Europe, particularly in the UK, where BA. 2 is the dominant strain.

Keri Althoff, a researcher at the Johns Hopkins Bloomberg School of Public Health, warned that CDC cases underestimate the real numbers because some people no longer get tested and others do home tests and do not report the results. He also said that not every sample is genetically determined to determine the variant.

Clearly, he said, “BA.2 is coming on stage.”

One reason the variant has gained ground, scientists say, is that it is about 30% more contagious than the original micron. In rare cases, research shows that people can get sick even if they already have a micron infection – although it does not appear to cause a more serious illness.

Vaccines seem equally effective against both types of microns, but unprecedented infections are possible. Experts also point out that vaccination rates are lower in the US than in the UK. About 74% of people aged 12 and over are fully vaccinated in the US, compared with 86% in the UK.

“We must emphasize that we are not protected in this country compared to our peers,” Topol said.

However, not all experts are equally concerned about the increase in BA-related cases in the US.2. Dr James Musser, head of genomic medicine and infectious diseases at the Houston Methodist, said the variant has so far caused only about 1% to 3% of cases in his medical system. The cases there are usually closely monitored by what is happening in the UK

He called BA.2 “something we watch” but said, “I’m not losing my sleep” about it.

This is how many scientists see the other variant that some in the public call “deltacron”, a hybrid that contains genetic information from both the delta and the micron.

Earlier this month, the World Health Organization’s Maria Van Kerkhove said the hybrid had been detected at “very low levels” in France, the Netherlands and Denmark. And two recent studies, which have not yet been evaluated by peers, show a small number of cases in the US.

Much remains unknown about the hybrid. There is no evidence that it causes a more serious illness and it does not seem to infect many people. CDC researchers identified nine samples, seven from the Mid-Atlantic region, in a study released Monday that has not yet been peer-reviewed. Topol, who did not participate in the investigation, said there was no indication that it could spread.

Given the virus’ ability to give birth to new mutants – and the rise of BA.2 – experts say humans should be vaccinated if they are not and have their own masks.

“Keep your watch,” Topol said. “This is not over.”
