In hard-hit Louisiana, the Ochsner Health System is seeing a significant decline in COVID-19 patients, now down to 530 -- dropping by nearly 250 patients in the last week, hospital CEO and president Warner Thomas said.

But in the wake of deadly Hurricane Ida, releasing patients from hospitals has been difficult, as some patients have no homes to return to, he said.

Hospitals in Oregon are "scrambling" to stay afloat with cases and hospitalizations "hovering at or near pandemic highs," the state epidemiologist, Dean Sidelinger, said at COVID-19 briefing Tuesday.

Oregon saw 16,252 new cases in its most recent weekly report – which is 13 times higher than the reported cases for the week ending July 4, Sidelinger said.

Hospitalizations and intensive care unit admissions are "alarmingly high" and hospitals are at a "saturation point" where they aren't "able to provide care to everyone arriving at their door," Sidelinger warned.

Former Phoenix Suns and Los Angeles Lakers player Cedric Ceballos, 52, tweeted that he's on his 10th day in the ICU battling COVID-19.

About 60 military medical personnel are heading in three, 20-person teams to Arkansas, Alabama and Idaho to help treat hospitalized COVID-19 patients following a request from FEMA, the U.S. Army North said.

The personnel, including doctors, nurses and respiratory therapists, were sent to hospitals in Coeur d'Alene, Idaho; Ozark, Alabama; and Little Rock, Arkansas.

Six teams had previously been dispatched to six other hospitals: three in Louisiana, two in Mississippi and one in Dothan, Alabama.

The Texas attorney general has filed lawsuits against six school districts that mandate masks, the office said Friday.

The lawsuits target the school districts of Richardson, Round Rock, Galveston, Elgin, Spring and Sherman for flouting Gov. Greg Abbott’s executive order prohibiting local entities from requiring masks -- what Texas Attorney General Ken Paxon referred to in a statement as "acts of political defiance."

In a statement to ABC News, Sylvia Wood, a spokesperson for Spring Independent School District, said the district had yet to be served and had no details about the lawsuit beyond a press release.

"Spring ISD will let the legal process unfold and allow the courts to decide the merits of the case," Wood said.

Elgin Independent School District Superintendent Jodi Duron also told ABC News the school district had not been served yet, and that schools in Travis County, part of Elgin ISD, are required to have students wear masks. "To the District’s knowledge, the Travis County Order has not been suspended," she said.

Round Rock Independent School District spokesperson Jenny LaCoste-Caputo told ABC News the school district is following Texas Education Agency guidance that allows for mask requirements "for adults or students for whom it is developmentally appropriate" and is working with local authorities "who advise us that masks remain an essential tool in stemming the spread of COVID-19 in our classrooms."

Sherman Independent School District told ABC News in a statement that it had not received any information on the lawsuit yet and for now "will continue to focus on promoting a safe and healthy learning environment for our students and staff."

ABC News has reached out to the other school districts for comment.

Nearly 90 school districts currently have mask mandates, according to a list compiled by Paxton's office. The attorney general anticipates more lawsuits if school districts "continue to defy state law," his office said in a statement.

Several school districts have sued the state to challenge the ban on mask mandates.

Last week, the Texas Education Agency said it is not enforcing the governor's executive order "as the result of ongoing litigation."
