Fauci backs CDC isolation recommendations
Dr. Anthony Fauci appeared on ABC News Live Wednesday and shared his thoughts on the U.S. Centers for Disease Control and Prevention's decision to lower its recommended isolation period to five days for asymptomatic patients.
Fauci also said that while new evidence shows omicron may be less severe than delta, people should still be cautious of contracting and spreading the virus.
"You can get people safely back out in a five day period so long as they wear a mask, if they are without symptoms. That is the science," he told ABC News Live. "The impact of that is to try and not be in a situation where we essentially have to shut down the entire country."
Fauci also said it would be too premature to be less worried based on evidence that omicron may be less severe.
"We are heartened by the fact that from the South African data, the data from the U.K., and the accumulating data in the United States that it looks like it is less severe," he said. "It's much more transmissible, which is something you need to take seriously."

3 Americans testing positive every second
The U.S. reported more than 1.9 million new cases this week, which equals about three Americans testing positive for COVID-19 every second.
The U.S. is now averaging 277,000 new cases each day, shattering the previous record average from Jan. 11, 2021, which was 250,000 cases each day, according to federal data.
Although this significantly high number is in large part due to the latest surge, it’s also attributable to the soaring demand for tests and backlogs of data following Christmas weekend.

The U.S. recorded more than 486,000 new COVID-19 cases in a day, marking the third straight day of record numbers, according to data released by the U.S. Centers for Disease Control and Prevention.

In the last week, the U.S. has reported more than 2.2 million new cases, which averages out to about 220 Americans testing positive for COVID-19 every minute.
The CDC will not be providing new data updates until Jan. 3, due to the New Year's holiday.
