US CDC warns Delta is making patients more severe and spreading like chickenpox
The Washington Post, citing internal documents from the US Centers for Disease Control and Prevention (CDC), said it appears that the delta strain of Covid-19 appears to exacerbate symptoms and spread as easily as chickenpox.
Those infected can infect 8-9 other people, while those infected with the original strain spread like the common flu. infecting an average of 2 other people
The CDC document also cited unpublished data from epidemic investigations and external research. People who have been vaccinated and who are infected with the delta strain may transmit it as easily as those who have not been vaccinated and are infected. Because vaccinated patients have the same amount of virus in their bodies as unvaccinated patients.
The issue, a federal health official told the Washington Post, was a major cause for the CDC to change its recommendation for vaccinated Americans to wear masks on Tuesday (July 27).
The document also states that It is expected that from now on there will be infection among those who have been vaccinated. and the numbers are likely to increase further. Because now there are many people who have been vaccinated. This is consistent with Singapore data that 75% of new infections occur among people who have had both single and double dose vaccinations.
The CDC also recommends that authorities communicate this clearly to the public to ensure the vaccine’s efficacy.
However, CDC documents confirm that people who have been vaccinated are safer. And vaccines reduce the risk of getting sick or die 10 times and the risk of infection 3 times.
“Vaccines prevent more than 90% of severe symptoms, but their effectiveness in preventing infection or transmission may be reduced. Therefore, there is infection in the vaccinated group and community transmission even after vaccination,” the document states.
After the document was published, CDC director Rochelle Walenski confirmed the document was authentic and the CDC is scheduled to release it today (July 30), which will help support advice for Americans. Come back to wear a mask that was announced 2 days ago.
