Fauci says if we didn't have the tools, he'd be way more worried about omicron
Asked how worried Americans should be about omicron and a post-holiday surge, Dr. Anthony Fauci said that if we didn't have vaccines, boosters and masks he'd "really be worried."
"But we have tools. So get vaccinated, get boosted," Fauci said at Wednesday's White House COVID-19 briefing.
CDC Director Rochelle Walensky said the agency expects to see omicron continue to grow.
"What does this mean for individuals and families as we head into the winter months? A time when families may be gathering with one another over the holidays? It means that it is vital for everyone to get vaccinated and boosted if they are eligible," Walensky said.
White House COVID-19 response coordinator Jeff Zients added, "We're not going to shut down our economy in any way. We're going to keep our schools and our businesses open."

Over 67,000 COVID-19 patients hospitalized in US amid winter surge
With winter closing in and COVID-19 cases on the rise, hospitals across the United States are once again facing the pressures of caring for thousands of patients.
More than 67,000 people are currently hospitalized with COVID-19 nationwide, according to federal data.
Rebecca Long, lead nurse in a COVID-19 intensive care unit at Nebraska Medical Center in Omaha, told ABC News that she and her team "literally do not have any ICU beds" available.
"I don't want anyone else's family member or loved one to have to be in the position where we say, like, we can't help you because we don't have the resources," Long said. "As health care providers, all we want to do is help people and we can't because we physically can't."
Dr. Kyle McCarty, medical director of emergency services at both HSHS St. Mary's and HSHS St. Vincent hospitals in Green Bay, Wisconsin, told ABC News that health care workers are feeling burned out after "being asked to do more with less."
"We're exhausted by the knowledge that we are the duct tape that is preventing a complete collapse of the health care system," McCarty said. "There's a national shortage of hospital staff, which is making it difficult to take care of patients the way that we want it. There aren't enough inpatient beds for the patients that need to be admitted to the hospital."
"This is a call for reinforcements, not a warning to stay away, because we don't want this to be the new normal," he added. "If we can recruit more health care teammates, it doesn't have to be."
