Delta variant may spread as easily as chickenpox, cause more severe infection: Reports
New York, Jul 30: The Delta variant of the coronavirus may cause more severe illness than all other known versions of the virus and spread as easily as chickenpox, media reports quoting an internal document from the US health authority said.
The document from the Centers for Disease Control and Prevention (CDC) outlines unpublished data that shows fully vaccinated people might spread the Delta variant, first identified in India, at the same rate as unvaccinated people, reports said.
The contents of the document a slide presentation were first reported by The Washington Post on Thursday.
Dr Rochelle P Walensky, the director of the CDC, acknowledged on Tuesday that vaccinated people with so-called breakthrough infections of the Delta variant carry just as much virus in the nose and throat as unvaccinated people and may spread it just as readily, if less often.
But the internal document lays out a broader and even grimmer view of the variant.
The Delta variant is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu and smallpox, and it is as contagious as chickenpox, according to the document, a copy of which was also obtained by The New York Times.
The Delta variant originally known as B.1.617.2 might cause more severe disease, according to the document.
The immediate next step for the agency is to acknowledge the war has changed, the document said.
The document's tone reflects alarm among CDC scientists about Delta's spread across the country, the NYT quoted a federal official, who has seen the research described in the document, as saying.
The agency is expected to publish additional data on the deadly variant on Friday.
The CDC. is very concerned with the data coming in that Delta is a very serious threat that requires action now, the official said.
There are roughly 35,000 symptomatic infections per week among 162 million vaccinated Americans, according to data collected by the CDC as of July 24 that was cited in the internal presentation.
But the agency does not track all mild or asymptomatic infections, so the actual incidence may be higher.
Infection with the Delta variant produces virus amounts in the airways that are tenfold higher than what is seen in people infected with the Alpha variant, which is also highly contagious, the document noted.
The amount of virus in a person infected with Delta is a thousandfold more than what is seen in people infected with the original version of the virus, according to one recent study.
The CDC document relies on data from multiple studies, including an analysis of a recent outbreak in Provincetown, Massachusetts, which began after the town's Fourth of July festivities.
Walensky told CNN that the Delta variant "is one of the most transmissible viruses we know about. Measles, chickenpox, this -- they're all up there."
And she said everyone in schools students, staff and visitors should wear masks at all times.
"The measures we need to get this under control they're extreme. The measures you need are extreme," Walensky said.
"The bottom line was that, in contrast to the other variants, vaccinated people, even if they didn't get sick, got infected and shed virus at similar levels as unvaccinated people who got infected," Walter Orenstein, who heads the Emory Vaccine Center and who viewed the documents, told CNN.
But vaccinated people are safer, the document indicates.
"Vaccines prevent more than 90 per cent of severe disease, but may be less effective at preventing infection or transmission," it reads.
"Therefore, more breakthrough and more community spread despite vaccination," the document adds.

US SC rejects 26/11 attack accused Tahawwur Rana’s plea seeking stay on his extradition to India
New York, Apr 7 (PTI): The US Supreme Court has rejected 26/11 Mumbai terror attack accused Tahawwur Rana's appeal seeking a stay on his extradition to India, moving him closer to being handed over to Indian authorities to face justice.
Rana, 64, a Canadian national of Pakistani origin, is currently lodged at a metropolitan detention centre in Los Angeles.
He is known to be associated with Pakistani-American terrorist David Coleman Headley, one of the main conspirators of the 26/11 attacks. Headley conducted a recce of Mumbai before the attacks by posing as an employee of Rana’s immigration consultancy.
Rana had submitted an ‘Emergency Application For Stay Pending Litigation of Petition For Writ of Habeas Corpus' on February 27, 2025, with Associate Justice of the Supreme Court of the United States and Circuit Justice for the Ninth Circuit Elena Kagan.
Kagan had denied the application earlier last month.
Rana had then renewed his ‘Emergency Application for Stay Pending Litigation of Petition for Writ of Habeas Corpus previously addressed to Justice Kagan’, and requested that the renewed application be directed to US Chief Justice John Roberts.
An order on the Supreme Court website noted that Rana's renewed application had been “distributed for Conference” on April 4 and the “application” has been “referred to the Court.”
A notice on the Supreme Court website Monday said that “Application denied by the Court.”
Rana was convicted in the US of one count of conspiracy to provide material support to the terrorist plot in Denmark and one count of providing material support to Pakistan-based terrorist organisation Lashker-e-Taiba which was responsible for the attacks in Mumbai.
New York-based Indian-American attorney Ravi Batra had told PTI that Rana had made his application to the Supreme Court to prevent extradition, which Justice Kagan denied on March 6. The application was then submitted before Roberts, “who has shared it with the Court to conference so as to harness the entire Court’s view.”
The Supreme Court justices are Associate Justice Clarence Thomas, Associate Justice Samuel A. Alito, Jr., Associate Justice Sonia Sotomayor, Associate Justice Elena Kagan, Associate Justice Neil M. Gorsuch, Associate Justice Brett M. Kavanaugh, Associate Justice Amy Coney Barrett, and Associate Justice Ketanji Brown Jackson.
In his emergency application, Rana had sought a stay of his extradition and surrender to India pending litigation (including exhaustion of all appeals) on the merits of his February 13.
In that petition, Rana argued that his extradition to India violates US law and the UN Convention Against Torture "because there are substantial grounds for believing that, if extradited to India, the petitioner will be in danger of being subjected to torture."
"The likelihood of torture in this case is even higher though as petitioner faces acute risk as a Muslim of Pakistani origin charged in the Mumbai attacks,” the application said.
The application also said that his “severe medical conditions” render extradition to Indian detention facilities a “de facto" death sentence in this case.
The US Supreme Court denied Rana's petition for a writ of certiorari relating to his original habeas petition on January 21. The application notes that on that same day, newly-confirmed Secretary of State Marco Rubio had met with External Affairs Minister S Jaishankar.
When Prime Minister Narendra Modi arrived in Washington on February 12 to meet with Trump, Rana’s counsel received a letter from the Department of State, stating that “on February 11, 2025, the Secretary of State decided to authorise” Rana’s "surrender to India,” pursuant to the “Extradition Treaty between the United States and India”.
Rana’s Counsel requested from the State Department the complete administrative record on which Secretary Rubio based his decision to authorize Rana’s surrender to India.
The Counsel also requested immediate information of any commitment the United States has obtained from India with respect to Rana’s treatment. “The government declined to provide any information in response to these requests,” the application said.
It added that given Rana’s underlying health conditions and the State Department’s findings regarding the treatment of prisoners, it is very likely “Rana will not survive long enough to be tried in India".
During a joint press conference with Prime Minister Modi in the White House in February, President Donald Trump announced that his administration has approved the extradition of "very evil" Rana, wanted by Indian law enforcement agencies for his role in the 26/11 Mumbai terror attacks, "to face justice in India”.
A total of 166 people, including six Americans, were killed in the 2008 Mumbai terror attacks in which 10 Pakistani terrorists laid a more than 60-hour siege, attacking and killing people at iconic and vital locations in Mumbai.
