As the world grapples with rising cases of the Delta variant coronavirus, new reports suggest that the variant may cause more severe illness than all other known versions of the virus and spread as easily as chickenpox. An internal document from the US health authority, the Centers for Disease Control and Prevention (CDC), outlines unpublished data showing that fully vaccinated people can spread the delta variant, the report said. which was first identified in India, at the same rate as for unvaccinated people. The contents of the document – a slide presentation – were first reported on Thursday by The Washington Post.
Vaccines can also spread covid
CDC Director Dr. Rochelle P. Valensky acknowledged that people vaccinated 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 more easily, if less frequently. Tuesday. But the internal document offers a broad and even grim view of the version.
Delta Version As Contagious As Chicken Pox
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.
Alarm on Transmissibility of Delta Variant
The document says the next next step for the agency is to acknowledge 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 that data coming into Delta is a very serious threat that requires action, 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 doesn’t track all mild or asymptomatic infections, so the actual incidence may be higher.
Why is the delta version more passable?
The document mentions that infection with the delta variant produces amounts of virus in the airways that are ten times higher than those 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 transmissible viruses we know of. Measles, smallpox, 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.
‘Vaccine may be less effective in preventing transmission’
“The bottom line was that, unlike other types, people who were vaccinated, 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 those who saw the document told CNN, but the people vaccinated 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, greater success and greater community spread despite vaccination,” the document states.
