Around 981,000 children in the United States tested positive for COVID-19 last week, according to a new report from the American Academy of Pediatrics and the Children's Hospital Association.

This "dramatic" uptick is a nearly 70% increase over the 580,000 added cases reported the week ending Jan. 6, and a tripling of case counts from the two weeks prior, the organizations said.

With nearly 9.5 million children having tested positive for the virus since the onset of the pandemic, that means 10% of those cases were in the past week alone.

In recent weeks, there has been a significant increase in demand for coronavirus tests as more Americans are exposed to the virus. Many students have also been tested as they return to school, which can lead to an increase in these numbers.

The organizations said there is an "urgent" need to collect more age-specific data to assess the severity of illness related to new variants as well as potential longer-term effects, and noted in their report that a small proportion of cases have resulted in hospitalization and death.

The rising number of pediatric cases has renewed the push for vaccination. Nearly 19% of children ages 5 to 11 and about 55% of those ages 12 to 17 are fully vaccinated, according to federal data.

All intensive care units are full in Oklahoma City, where 117 patients are in emergency rooms waiting for an open bed, Dr. Julie Watson, chief medical Officer of INTEGRIS Health, said Tuesday.

Some patients have been waiting more than 24 hours for an available ICU bed, Watson said.

"Our emergency departments are overflowing. Our health care professionals are exhausted. We've been working nearly nonstop for over two years now," Watson said at a news conference. "Omicron cases are rising faster than previous variants and we are struggling to keep up."

"We aren't able to care for patients the way we normally do," she continued. "It feels, and sometimes even looks, like a war zone. … We have to care for patients in hallways, sometimes closets."

Oklahoma City hospitals are also experiencing staffing shortages and supply chain shortages.

"Some days we don't have syringes, or saline or chest tube setups," she said.

Kansas will end its contact tracing program at the end January due to an overwhelming number of COVID-19 cases and a "diminished" willingness of people to take part, the state health department announced Tuesday.

"As we enter the third year of this pandemic, public health has to begin to adjust the level of response to help alleviate the strain on the Public Health system," Janet Stanek, acting secretary of the state's Department of Health and Environment, said in a statement. "The pandemic is far from over, but this step is a move toward managing COVID-19 as an endemic disease. The responsibility of protecting yourself and others belongs to all of us."

ESPN commentator Stephen A. Smith is opening up about his intense COVID-19 battle.

After Smith tested positive in December, he said he had a 103 degree fever every night.

"Woke up with chills and a pool of sweat. Headaches were massive. Coughing profusely," Smith said, according to The New York Post.

Smith said he was admitted to the hospital over New Year's with pneumonia in both lungs.

“They told me, had I not been vaccinated, I wouldn’t be here. That’s how bad it was," he said.

Smith is now back to work, but he said, "two-and-a-half, three weeks ago, I didn’t know if I was gonna make it.”
