Fauci declined to give a number. A total of 36 states are now seeing an increase in cases compared to the previous week.
"We are now having forty-plus thousand new cases a day".
The US is seeing a surge in coronavirus cases, with roughly 40,000 new ones coming in a day.

Elizabeth Warren (D-Mass.) about how many deaths and infections Americans should expect before the pandemic ends.
Then Fauci added, "I would not be surprised if we go up to 100,000 a day if this does not turn around, and so I am very concerned". During testimony before the Senate Health, Education, Labor and Pensions Committee Tuesday, Fauci said it's hard to precisely predict how bad the spread of the virus will get, but said he believes it will be "very disturbing". "I'm very concerned and I'm not satisfied with what's going on because we're going in the wrong direction if you look at the curves of the new cases, so we really have got to do something about that and we need to do it quickly".
Fauci said areas seeing recent outbreaks are putting the entire nation at risk, including regions that have made progress in reducing COVID-19 cases.

"Clearly we are not in total control right now", Fauci told the committee, warning that far worse conditions are ahead without new efforts to tamp down spread.
President Trump, who refuses to wear a mask at public events and in the past has mocked his rivals for wearing them, has signalled he wants to move on from the coronavirus crisis and focus on his re-election campaign.
