‘Contagious as chicken pox’: CDC releases new data on threat of delta variant

According to the data, the delta variant spreads between even people who are vaccinated

The delta variant of the coronavirus is as “contagious as chicken pox,” according to new data from the Centers for Disease Control and Prevention — and it can be readily spread by fully vaccinated people to others who are fully vaccinated, leading to far more COVID-19 breakthrough cases than previously reported. The data also projects that delta can cause more severe illness than earlier variants of the virus.

A memo on the data — released publicly Friday — shows CDC scientists wanted to recommend “universal masking is essential to reduce transmission of Delta.” Health experts worry the information could shake public confidence in the efficacy of COVID-19 vaccines and emphasize the shots will still protect against severe illness, hospitalization and death. The CDC released the data after it was leaked to news media.
