US media reports suggested the delta version of the coronavirus could spread as easily as chickenpox
US media reports, quoting an internal document from the US health authority, said that the delta version of the coronavirus can cause more severe illness than all other known versions of the virus and spread as easily as chickenpox. The report said the Centers for Disease Control and Prevention (CDC) document outlines unpublished data showing that fully vaccinated people can spread the delta variant, previously identified in India, to the same At the rate that was for people without vaccinations.
The contents of the document – a slide presentation – were first reported on Thursday by The Washington Post. CDC Director Dr. Rochelle P. Valensky acknowledged Tuesday that people with the so-called breakthrough infection of the delta variant have the same amount of virus in their nose and throat as people without vaccinations and can spread it less easily. Often.
But the internal document offers a broader and even grim view of the version. The delta variant is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu and smallpox, and is as contagious as chickenpox, according to the document, a copy of which was also obtained by The New The York Times went.
According to the document, the delta version – originally known as B.1.617.2 – can cause more severe disease. The document said the immediate next step for the agency is to “accept that the war has changed”.
The tone of the document reflects alarm among CDC scientists about the spread of delta across the country, the NYT said, citing a federal official who has seen the research described in the document.
The agency is expected to publish additional data on the fatal version on Friday. “CDC. is very concerned with the data coming into Delta that Delta is a very serious threat that needs action right now,” the official said.
There are about 35,000 symptomatic infections per week among the 162 million vaccinated Americans cited in the internal presentation, according to data collected by the CDC as of July 24.
But the agency does not track all mild or asymptomatic infections, so the actual incidence may be higher.
The document mentions that infection with the delta variant produces an amount of virus in the airways that is ten times higher than in people infected with the alpha variant, which is also highly contagious.
According to a recent study, the amount of virus in a person infected with Delta is a thousand times higher than in people infected with the original version of the virus.
The CDC document relies on data from several studies, including an analysis of the recent outbreak in Provincetown, Massachusetts, which began after the city’s Fourth of July celebration.
Valensky told CNN that the delta variant is “one of the most spreading viruses we know about. Measles, chickenpox, this — they’re all out there.” And she said everyone in schools – students, staff and visitors – must wear masks at all times.
“The measures we need to get this under control are extreme. The measures you need are extreme,” Valensky said. “The bottom line was that, unlike other types, vaccinated people, even if they weren’t sick, became infected and shed the virus at similar levels to those who were infected,” said Walter Orenstein, who heads Emory Vaccines. The center and the one who saw the documents told CNN.
But vaccinated people are safe, the document indicates. “Vaccines prevent more than 90 percent of severe disease, but may be less effective in preventing infection or transmission,” it reads.
“Therefore, despite vaccination there is greater success and greater community spread,” the document says.
