Utah is “in the middle of a very, very serious spike,” Greg Bell, president and CEO of the Utah Hospital Association, said Thursday.

The state’s seven-day positivity rate has climbed to 18.1%, up from 15% last week, state epidemiologist Angela Dunn said at a news conference.

Utah’s ICUs are 72% full, Dunn said.

“Our hospitals are getting too full to function,” Gov. Gary Herbert warned.

Herbert said gatherings will be limited to 10 people.

“I know you have holidays coming up, Halloween and Thanksgiving … it can be done,” Hebert said. “That will help us get past this surge.”

Ohio hit another record high number of daily cases on Thursday, with 3,590 more people diagnosed, Gov. Mike DeWine said.

“It’s the first time we’ve surpassed 3,000 [daily] cases -- and 25% more than Saturday’s previous record high,” he tweeted.

Ohio now has over 208,000 COVID-19 cases and at least 5,275 deaths.

"The virus is raging throughout Ohio. There is no place to hide,” DeWine tweeted.

“Today I'm calling on the leaders of each county, each community, in Ohio to come together to create a COVID Defense Team. This is what we need to fight back. It should include commissioners, mayors, hospital leaders, business leaders, religious leaders, health commissioner, etc.,” DeWine continued. “These teams should assess their county's situation, inventory assets, and focus on what steps are needed to turn this around.”

A Centers for Disease Control and Prevention (CDC) case study released Thursday found that one ninth grade boy, who tested PCR negative before traveling, likely spread COVID-19 to over 100 people at a boys’ overnight summer school retreat in Wisconsin.

Among the 152 high school aged boys, counselors and staff members, there were 118 confirmed COVID-19 cases and 38 probable cases, the CDC said.

The tightly packed students, in session from July 2 to Aug. 11, didn't wear masks and shared dorms with beds close together.

The ninth grade boy who likely set off the spread had a negative PCR test less than a week before the retreat, but he developed symptoms the day after arriving, according to the CDC. A family member of the boy tested positive while he was at the retreat.

In order to lower the risk in this type of setting, the CDC said it is critical to implement pre-arrival quarantine and testing, symptom monitoring, early identification and isolation of cases, mask use, distancing and enhanced hygiene and disinfection practices.

Liege, Belgium, is emerging as an epicenter of Europe's worsening coronavirus crisis.

In Liege, where there's a roughly 41% infection rate, the local hospital is at full capacity. ICU numbers have tripled in the last three weeks.

A doctor told ABC News that health workers who have tested positive for COVID-19 are still treating patients to keep the hospital system from crashing.

Just days after issuing a countywide curfew, a judge in El Paso County, Texas, ordered a two-week shutdown of nonessential businesses -- a move that was met with pushback from the state attorney general.

Judge Ricardo Samaniego announced Thursday that beginning at midnight, El Paso County will enter a two-week shutdown of nonessential businesses and services, including tattoo parlors, hair salons, gyms and in-person dining. Essential businesses, including polling sites and schools that provide meals, will remain open, he said. 

"Since the inception of this pandemic, El Paso County has never seen this level of infections through our community," Samaniego told reporters at a press briefing Thursday evening. "Our hospitals are at capacity, our medical professionals are overwhelmed and if we don't respond, we will see unprecedented levels of deaths."

The judge said that El Paso had seen a 365.2% increase in COVID-19 hospitalizations since the beginning of the month.

Following the announcement, Texas Attorney General Ken Paxton tweeted that Samaniego "has no authority to shut down businesses" and was violating Gov. Greg Abbott's executive order.

"My office is quickly exploring all legal actions," Paxton said.

El Paso Mayor Dee Margo also questioned the new county order.

"The Judge did not consult me and refuses to return my call, so I am seeking clarification from the Attorney General on the new County order, which does not supersede the Governor's orders," Margo said in a statement.

"We must strike a balance of keeping our neighbors safe while not destroying people's abilities to feed their families," he added.

Several community leaders joined Samaniego in supporting the order.

"In recent days it's apparent that stricter measures are necessary to flatten the curve and, bottom line, save lives," Texas state Rep. Cesar Blanco, a Democrat, said at Thursday's briefing. "The status quo, it's no longer working."

There were 937 hospitalizations due to COVID-19 in El Paso on Thursday, a new record, University Medical Center CEO Jacob Cintron said.

On Sunday, Samaniego ordered a two-week curfew to limit mobility in the community amid rising COVID-19 cases and hospitalizations, and after intensive care units at all area hospitals reached 100% capacity as of Saturday. The curfew has been imposed for 10 p.m. to 5 a.m., and trick-or-treat activities on Halloween are not allowed, Samaniego said.
