The United States is likely in for a hard winter as the Omicron variant of Covid-19 spreads rapidly, Dr. Anthony Fauci says, straining a health care system already battered by the Delta variant. "It's going to take over," Fauci, the nation's top infectious disease expert, said of the Omicron variant on CNN's "State of the Union" on Sunday, urging Americans to get vaccinated and get their booster shots. "And be prudent in everything else you do: When you travel in your indoor settings that are congregated, wear a mask."
"We can't walk away from that, Jake, we can't," he told CNN's Jake Tapper. "Because with Omicron, that we're dealing with, it is going to be a tough few weeks to months as we get deeper into the winter." According to the World Health Organization, Omicron cases are doubling every 1.5 to 3 days with documented spread. And in the US, it's expected to become the "dominant strain" in the coming weeks, the director of the US Centers for Disease Control and Prevention said Friday.
