There has been a nationwide decrease in the seven-day averages for tests, cases, hospitalizations and deaths in the U.S, according to the COVID Tracking Project.

Many states are reporting a decrease in the number of new cases per million people, though California, Virginia and South Caroline reported more than 1,000 new cases per million Sunday.

Along with the states that do not regularly report on Sunday, Washington reported data system issues over the weekend. There will be some disruptions to reporting expected on Monday due to Martin Luther King Jr. Day.

States reported 1.8 million tests, 186,000 cases, 124,387 people currently hospitalized with COVID-19, and 2,044 deaths on Sunday, according to the COVID tracking project.

The number of patients entering hospitals in the U.K. every day is showcasing the dire situation as the new variant of the COVID-19 virus that originated there continues to spread.

Sir Simon Stevens, Chief Executive of England’s NHS, announced Sunday that "every thirty seconds across England another patient is being admitted to hospital with coronavirus."

Hospitals and staff are under “extreme pressure,” Stevens said.

Prime Minister Boris Johnson also announced Sunday that the vaccine was being administered at a rate of "140 jabs a minute."

The state of California is poised to surpass 3 million positive COVID-19 cases within two days, according to data from the California Department of Public Health.

On Sunday, the state health department reported 42,229 new cases and 432 new deaths.

Los Angeles County, the hardest hit in the state, surpassed 1 million cases on Saturday. Dodger Stadium, the largest vaccination site in the country, reopened on Friday, but officials told ABC News they only have enough doses to last until Wednesday.

New York Gov. Andrew Cuomo is urging the federal government to send more COVID-19 vaccines to the state as the variant that originated in the U.K. continues to spread.

Nearly 14,000 positive tests were reported Sunday, with 18 known cases of the variant and an infection rate of 5.6%, Cuomo announced.

While 7 million New York residents are currently eligible to receive the vaccine, the federal government sent less vaccines than what was expected, he added.

"We have the weapon that will win this war and we can see the light at the end of the tunnel, but how fast we get there depends upon two things-our own individual actions and the federal supply, which is where we are facing the greatest challenge," Cuomo said in a statement.

Disneyland Resort in Anaheim, California, opened as a mass COVID-19 vaccination site Wednesday.

About 3,000 people were expected to receive the vaccine on the first day, with about an hour-and-a-half wait time, county officials said. The site ultimately should be able to vaccinate over 7,000 people a day, Orange County First District Chairman Andrew Do said at a press briefing.

Vaccinations are by appointment only. Those without an appointment and proper identification will be turned away, the Orange County Health Care Agency warned repeatedly on Twitter Wednesday.

Over 10,000 people signed up for a slot within two hours of online registration opening on Tuesday, officials said. Disneyland has been closed to parkgoers since last spring.

Other mass vaccination sites are slated to open in the hard-hit state, including Dodger Stadium in Los Angeles and Cal Expo in Sacramento. Petco Park in San Diego also opened earlier this week as a vaccination site.

People in Phase 1A -- health care workers and long-term care residents -- currently have the highest priority to receive vaccines in California.

On Wednesday, the state announced that people 65 and older are also now eligible, in an effort to help speed up vaccine distribution.
