“I feel compelled to underscore for you the need for each of us to remain steadfast in our commitment to taking all of the appropriate steps to protect ourselves and our communities,” Walensky said. And one very important step, according to the CDC director, is steering clear of one kind of place in particular: “Avoid crowds and poorly ventilated spaces,” she said plainly. “There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others and travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes),” the CDC warned in September. “In general, indoor environments without good ventilation increase this risk.” Read on to find out what else the new CDC chief says to do and what not to do as these new variants start to spread.

As a result, the U.S. State Department issued a serious warning this week that all non-essential international travel should be avoided amid COVID. “The Department of State is committed to helping U.S. citizens overseas who find themselves in dire situations, but that assistance is likely to be limited,” Ian Brownlee, Bureau of Consular Affairs Acting Assistant Secretary at the U.S. State Department, said during a Jan. 26 press briefing. “Our main message to U.S. citizens considering travel abroad remains the same: Seriously reconsider going overseas right now. If you’re overseas right now, it’s going to be harder to come home for a while.” And for more COVID news sent right to your inbox, sign up for our daily newsletter. Of course, as the CDC has been recommending for the past 11 months, Walensky bluntly told Americans: “Wear a mask.” This is in line with the executive order President Joe Biden signed during his first week in office, making mask mandatory in airports and on trains, planes, buses, and maritime vessels.

Walensky’s final point was the one that offers the best long-term solution to the pandemic. “When it’s your turn, please roll up your sleeve and get vaccinated,” she said. Her colleague, White House COVID adviser Anthony Fauci, MD, reiterated this point at the press briefing, saying that vaccinations both protect you as an individual and also lessen the likelihood of new strains emerging. “The fundamental principle of getting people vaccinated as quickly and as efficiently as you possibly can, will always be the best way to prevent the further evolution of any mutant,” he said. “Because when you do that, you prevent replication and replication is essential for mutation.” And for more on the latest news regarding vaccinations, check out why Dr. Fauci Says Doing This After Getting Vaccinated Is a Huge Mistake.
