The Delta coronavirus variant appears to be as contagious as chickenpox, a leaked internal document from the Centers for Disease Control and Prevention warned.
The document, first obtained by The Washington Post, also warned that the variant is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu, and smallpox.
The document also said there is early evidence that fully vaccinated people could spread the virus as easily as unvaccinated people.
But it said that vaccines protect people from severe disease and death caused by the Delta variant by up to 10 times.
