The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 628,000 Americans have died from COVID-19 while over 4.4 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 59.9% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

Pfizer/BioNTech submit early booster shot data to FDA
Pfizer/BioNTech have submitted early booster shot data to the Food and Drug Administration.
Phase 1 data found that people given a third shot eight to nine months after their primary doses had a boosted immune response and higher neutralizing antibody levels against the delta variant.
Pfizer/BioNTech plan to continue to study booster shots and submit additional data to the FDA.
It's not clear when or if the FDA and Centers for Disease Control and Prevention might recommend booster doses for all. Only severely immunocompromised people are currently eligible.

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.
Positivity rate climbs to 25% at Children's Hospital New Orleans
The positivity rate has climbed to 25% at Children's Hospital New Orleans, Dr. Mark Kline, the hospital's physician-in-chief, told ABC News on Sunday.
The hospital had 12 pediatric patients on Sunday. Half of them were under 2 years old, Kline said.
Five of the 12 patients in the hospital were in the ICU: an 8-week-old, a 3-month-old, a 13-month-old, a 23-month-old and a 17-year-old, Kline said.
"As we see more children infected and ill with COVID-19, it occurs to me that our children have become the collateral damage of many adults who frame refusal of masks and vaccines as an issue of personal freedom rather than the common-sense public health measures that they are," Kline said.
"Children currently have no way out of this pandemic other than through the advocacy and personal responsibility of their parents and all adults," Kline added. "So far, we are failing them miserably."

2nd field hospital to open in Mississippi following record-number of hospitalizations
Another field hospital with critical care capacity is now under construction on the University of Mississippi Medical Center’s campus – just days after the first in the state was opened in the parking garage of the medical center.
The opening comes in response to a record number of COVID-19-related hospitalizations across the state, and an "increasingly dire" crisis, the hospital said on Monday.
On Monday, Samaritan’s Purse began setting up the second surge facility for adult patients in another parking lot on the UMMC campus. Medical staff from the organization will provide care for up to 32 patients at a time. The facility will include five intensive care beds.
"We have approximately 30 patients statewide, including upwards of 10 individuals at UMMC, waiting for ICU beds at any given time," Dr. LouAnn Woodward, vice chancellor of health affairs and dean of the School of Medicine at UMMC, said in a statement. "These startling numbers prove just how critical the COVID-19 crisis is in the state."
Hospitals around the state will continue to transfer severely ill COVID-19 patients to UMMC for a higher level of care.
