CDC Report Warns ‘War Has Changed’ Due To Highly Contagious Delta

The Washington Post: ‘The War Has Changed’: Internal CDC Document Urges New Messaging, Warns Delta Infections Likely More Severe 
The delta variant of the coronavirus appears to cause more severe illness than earlier variants and spreads as easily as chickenpox, according to an internal federal health document that argues officials must “acknowledge the war has changed.” The document is an internal Centers for Disease Control and Prevention slide presentation, shared within the CDC and obtained by The Washington Post. It captures the struggle of the nation’s top public health agency to persuade the public to embrace vaccination and prevention measures, including mask-wearing, as cases surge across the United States and new research suggests vaccinated people can spread the virus.

The New York Times: C.D.C. Internal Report Calls Delta Variant As Contagious As Chickenpox 
Dr. Rochelle P. Walensky, the director of the agency, 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 obtained by The New York Times.

CNN: CDC Document Warns Delta Variant Appears To Spread As Easily As Chicken Pox And Cause More Severe Infection 
CDC Director Dr. Rochelle Walensky confirmed the authenticity of the document, which was first reported by The Washington Post. "I think people need to understand that we're not crying wolf here. This is serious," she told CNN. "It's one of the most transmissible viruses we know about. Measles, chickenpox, this -- they're all up there." The CDC is scheduled to publish data Friday that will back Walensky's controversial decision to change guidance for fully vaccinated people. She said Tuesday the CDC was recommending that even fully vaccinated people wear masks indoors in places where transmission of the virus is sustained or high. (LeBlanc, Fox and Cohen, 7/29)
