Video: GBAC Explains Latest CDC Mask Advisory

Experts examine the science behind the CDC’s latest advisory regarding both vaccinated and unvaccinated individuals and the use of face coverings.

July 29, 2021

Earlier this week, the U.S. Centers for Disease Control and Prevention (CDC) updated its guidance on the usage of face masks to prevent the spread of COVID-19.

The CDC issued the revised guidelines based on the rise in cases nationwide of the B.1.617.2. variant of COVID-19, also known as the delta variant. The agency now recommends that fully vaccinated people wear masks indoors when in areas with “substantial” and “high” transmission of the virus.

In this Cleaning Industry Alert, Patricia Olinger, executive director of the Global Biorisk Advisory Council™ (GBAC), a Division of ISSA, and Senior GBAC Director Dr. Gavin Macgregor-Skinner examine the science behind the CDC’s latest advisory regarding both vaccinated and unvaccinated individuals and the use of face coverings.

The GBAC experts also put into perspective what individuals and organizations should concentrate on as the pandemic lingers, which continues to be cleaning, disinfecting, and proper hygiene and safety best practices.
