The Centers for Disease Control and Prevention is warning of another rise in COVID-19 cases, with the seven-day average of daily infections up by 5% or more in 27 states. CDC Director Rochelle Walensky on Monday asked U.S. residents to continue to wear masks, to avoid crowds and to delay travel, even if they’ve been vaccinated.

Dr. Rochelle Walensky: “We are at a critical point in the pandemic, a fork in the road, where we, as a country, must decide which path we are going to take. We must act now. And I am worried that if we don’t take the right actions now, we will have another avoidable surge, just as we are seeing in Europe right now and just as we are so aggressively scaling up vaccination.”
