The White House COVID task force held a news briefing on Tuesday as information on the omicron variant continues to develop.

U.S. health officials said Sunday that while the omicron variant of the coronavirus is rapidly spreading throughout the country, early indications suggest it may be less dangerous than delta, which continues to drive a surge of hospitalizations.

President Joe Biden’s chief medical adviser, Dr. Anthony Fauci, told CNN’s “State of the Union” that scientists need more information before drawing conclusions about omicron’s severity.

Reports from South Africa, where it emerged and is becoming the dominant strain, suggest that hospitalization rates have not increased alarmingly.

“Thus far, it does not look like there’s a great degree of severity to it,” Fauci said. “But we have really got to be careful before we make any determinations that it is less severe or it really doesn’t cause any severe illness, comparable to delta.”
