Washington Post: CDC document warns Delta variant appears to spread as easily as chicken pox and cause more severe infection
CNN
The Delta coronavirus variant surging across the US appears to cause more severe illness and spreads as easily as chicken pox, according to an internal document from the US Centers for Disease Control and Prevention obtained by The Washington Post.
The document -- a slide presentation -- outlines unpublished data that shows fully vaccinated people might spread the Delta variant at the same rate as unvaccinated people, according to the Post. A federal health official told the newspaper that the data, which is expected to be released Friday, played a large role in the CDC's updated mask guidance, which recommends that fully vaccinated people wear masks indoors when in areas with "substantial" and "high" transmission.More Related News
