CDC internal report says Delta variant as contagious as chickenpox - NYT

The U.S. Centers for Disease Control and Prevention (CDC) has described the Delta variant of the coronavirus as being as transmissible as chickenpox and cautioned it could cause severe disease, the Washington Post said, citing an internal CDC document.

The variant was also more likely to break through protections afforded by the vaccines, but the health authority said such incidents were very rare, the CDC report posted on the Washington Post website showed. In its summary, the CDC report said Delta is highly contagious, likely more severe than other variants and breakthrough infections may be as transmissible as unvaccinated cases.
