'And so when you look at the curve of acceleration of seven-day averages of cases per day, it is going up in a very steep fashion.'
Cases have been surging in the United States over the last month.
On Wednesday, the U.S. recorded 106,557 new cases of coronavirus with a seven-day rolling average of 90,576.

Fauci explained that those cases could quickly accelerate.
'Remember, just a couple of months ago, we were having about 10,000 cases a day,' he continued.
