Coronavirus updates: US reports nearly 300,000 new cases in all-time high

The U.S. reported 3,903 deaths on Wednesday, a new record for daily fatalities, according to The COVID Tracking Project.

Hospitalizations also reached a record high with 125,220 and there were 225,671 new cases, according to the tracking project.

"Holiday reporting delays are still markedly affecting testing, case, and deaths figures," the group tweeted.

The COVID Tacking Project said the death count included a backlog of 200 fatalities from Washington state.

"Even without this backlog, today's total would still be the highest to date," the tracking project tweeted.

It warned that more data disruptions are expected with the New Year's Day weekend.

Texas health officials announced a record 326 deaths on Wednesday.

The previous record was set on July 23 with 278 deaths, according to health data.

The state had 17,458 new daily cases and 11,992 hospitalizations, according to the health department. There are currently 602 intensive care unit beds remaining in Texas, health officials said.

Arizona Gov. Doug Ducey issued an executive order Wednesday to speed up access to the COVID-19 vaccine in the state.

The Arizona Department of Health Services will take the lead in the vaccination rollout under the order. The department is tasked with establishing and delivering a statewide implementation model.

Currently, Arizona counties are responsible for their own implementation plans.

"This is a health emergency, and we need all levels of government and our health system operating as such. Vaccines don't do any good sitting in a freezer," Ducey said in a statement.

The state health department will have the authority to establish private distribution sites, according to the executive order.

There is no statewide data for vaccinations. The executive order mandates that all counties display their vaccination numbers on their websites and share the info with the state health department.

Maricopa County, which leads the state with over 314,000 cases, has administered at least 36,000 doses as of Wednesday, according to the county's health department.

Los Angeles County officials said the National Guard will be deployed next week to assist the medical examiner's office with its growing number of COVID-related deaths.

Hilda Solis, the chair of Los Angeles County Board of Supervisors, said six guardsmen will arrive on Jan. 4.

"They will be assisting until the end of January. It might be extended if warranted," she said at a news conference.

The deployment comes as the county recorded 274 additional deaths Wednesday, bringing the death toll to 10,056.

"The average number of deaths is about 150 people a day," Dr. Barbara Ferrer, the director of the Los Angeles County Department of Public Health, said at a news conference.
