That number was up from 282 on Thursday.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 643,000 Americans have died from COVID-19 while over 4.5 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 61.7% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the U.S. Centers for Disease Control and Prevention.

Pfizer studying new pill in hopes it'll help with mild COVID symptoms
Pfizer is launching a large clinical study for a new pill that it hopes could prevent worse symptoms for patients with mild COVID-19.
The first participant has now been dosed in this "pivotal Phase 2/3 clinical trial," Pfizer said.
Drugs like Remdesivir and Dexamethasone can help people recover faster, but those are only reserved for people who are extremely ill and in the hospital.
If proven effective, Pfizer will ask the FDA for authorization.

Virginia Tech disenrolls 134 students who didn't meet vaccination policy
Virginia Tech says 134 students have been disenrolled after they didn't comply with COVID-19 vaccine requirements.
The university's roughly 37,000 students were required to submit vaccination documentation or receive a medical or religious exemption, Virginia Tech said.
"The university does not know whether any of these [134] students were not planning to return for reasons unrelated to the COVID-19 vaccine requirement," Virginia Tech said.

Pediatric hospitalizations nearly 4 times higher in states with low vaccination: CDC
Two studies to be published Friday found fewer pediatric hospitalizations among children and communities with higher vaccination rates, the director of the U.S. Centers for Disease Control and Prevention said.
In one study, national data from August showed that children were nearly four times more likely to be hospitalized with COVID-19 in the states with the lowest vaccination rates when compared to states with the highest rates -- proof that "cocooning" children with vaccinated people keeps them safe, Dr. Rochelle Walensky said at a White House briefing Thursday.
The second study, which looked at hospitalizations rates in 12- to 17-year-olds across 14 states during July, found that adolescents who were unvaccinated were 10 times more likely to be hospitalized with COVID-19 than their fully vaccinated peers, Walensky said.
"Both studies, one thing is clear: cases, emergency room visits and hospitalizations are much lower among children and communities with higher vaccination rates," Walensky said. "We must come together to ensure that our children, indeed, our future, remain safe and healthy during this time."
