The number of people to test positive for the novel coronavirus in the U.S. surpassed 50,000 for the first time ever on Wednesday, Johns Hopkins data shows.

Driving the news: The pandemic is accelerating across the U.S., with the Sun Belt being hit particularly hard. Daily coronavirus case records were reported on Wednesday in Texas (8,076), Arizona (4,878), Georgia (2,946), North Carolina (1,843) and Tennessee (1,806).

  • As the outbreak worsens throughout the South and the West, caseloads are growing fastest in counties with large communities of color, Axios' Caitlin Owens notes.

By the numbers: Across the U.S., almost 2.7 million people had tested positive for COVID-19 from more than 32.8 million tests as of Thursday morning, per Johns Hopkins. Over 128,000 Americans have died from the virus.

  • The U.S. reported on Wednesday 50,655 new cases in a single day.

What they're saying: NIAID director Anthony Fauci testified to a Senate committee Tuesday that the U.S. was seeing about 40,000 new cases daily and that number would rise rapidly "if this does not turn around." He said he would "not be surprised" if the U.S. begins reporting up to 100,000 new cases per day.

  • On Monday CDC principal deputy director Anne Schuchat told The Journal of the American Medical Association, "This is really the beginning, and what we hope is that we can take it seriously and slow the transmission."
  • President Trump told Fox Business Wednesday, "We're heading back in a very strong fashion, with a V. And I think we're going to be very good with the coronavirus. I think at some point that's going to sort of just disappear, I hope. ... And I think we're going to have a vaccine very soon too."

Between the lines: The Centers for Disease Control and Prevention warned in June that the country's total number of infections may be closer to more than 23 million — or around 10 times the 2.3 million confirmed cases at the time.

  • Former FDA commissioner Scott Gottlieb told CNBC Wednesday, "We're probably diagnosing maybe one in 10 infections nationally. So the 40,000–50,000 infections that we're diagnosing each day right now really represents 400,000–500,000 infections. "

Of note: State governors across the country have been pausing or adjusting reopening plans in recent days in response to the surging cases.

There’s not much good news about kids and coronavirus

The more we learn about kids and the coronavirus, the riskier reopening schools for in-person learning appears to be, at least in areas with high caseloads.

Why it matters: There have already been many reports about the virus spreading through schools and summer camps, and evidence has begun to support the notion that children can play a key role in community transmission.
