The White House's chief medical adviser said the latest wave of the COVID-19 flu could peak by the end of the month.
Fauci told CNBC's "Closing Bell" that the Omicron variant of the coronaviruses peaked in South Africa at the end of November.
The Omicron variant is the most common coronaviruses in the US.
Fauci told CNBC that the peak probably will be more than a couple of weeks, considering the size of the US and the country's levels of vaccination.
A recent University of Texas report estimated that US Omicron cases could peak between January 18 and February 3, while daily COVID-19 cases could bottom out in March.
Fauci told CNBC that there's no guarantee that the Omicron variant could accelerate the end of the Pandemic.
If you have a very transmissible virus that replaces another virus, that would be a positive outcome.
A small study by scientists in South Africa suggests that people with the Omicron variant could have better immunity against the Delta variant.
This virus has fooled us before. We thought the vaccines would be fine. Fauci told CNBC that Delta threw a monkey wrench into everything.
He told CNBC that there was no guarantee that the end of a serious outbreak would be achieved.
