John,

The COVID-19 Delta variant has moved the pandemic into a new phase. As a recent internal CDC document put it: "The war has changed."

Fortunately, there are clear steps you can take to protect yourself and others. First, get the vaccine. Second, follow the CDC's updated guidance on mask wearing.

In our Road to Recovery series, Dr. Kelly Henning, an epidemiologist who leads our Public Health program, looks at what we know -- and why we need to be masking up again:

With people returning to offices and kids heading back to schools, we all have a role to play in stopping the spread of the Delta variant.

COVID vaccines have proven effective at preventing severe illness and deaths. And by following the CDC's guidance on mask wearing, you can help protect those -- like kids under 12 -- who can't get vaccinated yet.

Learn more about what has changed, and what precautions you can take, in our latest Road to Recovery video:
