In his Tuesday testimony before members of Congress, infectious disease expert Dr. Anthony Fauci spoke about his concerns over certain states’ reopening plans and the surge of cases the nation has seen in past days. He noted the death totals will be concerning and the country is “going in the wrong direction.”

Before the Senate Health, Education, Labor and Pensions committee, Fauci fielded questions from senators — one question covered new data showing a 40,000 increase in cases one day last week. He said that “we’re not in control” and it would come at no surprise to him if the nation saw an increase by 100,000 cases in one day.

“The numbers speak for themselves,” Fauci testified. “I’m very concerned. I’m not satisfied with what’s going on because we’re going in the wrong direction.”

According to the Guardian, Fauci called out younger Americans to follow guidelines.

“What we saw were a lot of people who maybe felt because they think they are invulnerable – and we know many young people are not because they’re getting serious disease – that therefore their getting infected has nothing to do with anyone else,” Fauci said.

Fauci urged the public to follow CDC and local guidelines, including the wearing of a mask in public and maintaining six feet distance from others.
