Delta variant as contagious as chickenpox, says CDC
The US Centers for Disease Control and Prevention (CDC) has described the Delta variant of the coronavirus to be as contagious as chickenpox and could cause severe illness, the New York Times reported, citing an internal CDC document.
The report said that the agency’s reverse course on masking guidelines for fully vaccinated Americans on Tuesday was based on this document.
The CDC’s figures show that the vaccines are highly effective in preventing serious illness, hospitalization and death in vaccinated people, the report said, citing experts.
The Delta variant is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu and smallpox, the report said.
