Delta Variant: Infections and Spread
On July 27, 2021, CDC released updated guidance on the need for urgently increasing COVID-19 vaccination coverage and a recommendation for everyone in areas of substantial or high transmission to wear a mask in public indoor places, even if they are fully vaccinated. CDC issued this new guidance due to several concerning developments and newly emerging data signals.
The Delta variant causes more infections and spreads faster than early forms of SARS-CoV-2, the virus that causes COVID-19.
Prevent the Spread. Act
The CDC recommends a series of everyday actions to prevent the spread of COVID-19:
Avoid close contact with people who are sick.
Avoid touching your eyes, nose, and mouth.
Stay home when you are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
Clean and disinfect frequently touched objects and surfaces using cleaning spray or a wipe.
Wash your hands often with soap and water for at least 20 seconds.
If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol.
Follow the CDC's recommendations for using a facemask:
Facemasks should be used by people who show symptoms of COVID-19 to help
prevent the spread of the disease to others.
The use of facemasks is critical for health workers and people who are taking care of someone in close settings (at home or in a health care facility).
Facemasks should completely cover your nose and mouth.
