Hospitalizations could reach 32,800 per day by Sept. 1: Forecast
The U.S. could see as many as 32,800 hospitalizations per day by Sept. 13, according to the COVID-19 Forecast Hub at U Mass Amherst, which is used by the Centers for Disease Control and Prevention. The low end of the forecast is 9,000 per day.

Doctor talks treating kids with RSV, COVID-19
As COVID-19 cases surge pediatricians are experiencing a first: sick children facing both respiratory syncytial virus, or RSV, and COVID-19.
"We've not seen this before -- we have two very highly contagious respiratory viruses circulating at the same time, particularly throughout the South around Texas and neighboring states," Dr. Jim Versalovic, pathologist-in-chief at Texas Children's Hospital, told ABC News Live on Monday.
Infants, young children and older adults are most at-risk for RSV, a respiratory virus that's usually more prevalent in the fall and winter. RSV kills 100 to 500 children under 5 each year, according to the Centers for Disease Control and Prevention.
"It's not surprising now to see children being impacted with both viruses, particularly infants and young children who are most susceptible to respiratory syncytial virus," Versalovic said.
He said in "recent weeks we've had 30% or more of our pediatric ICU beds [filled] with RSV infections," including some children also with COVID-19, which "could "mean more severe respiratory illness."
"We do know how to treat these children with RSV and with COVID. And so, for now we're managing that, but it is certainly a new challenge for us," Versalovic said.
