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.

A new, more infectious variant of the novel coronavirus that was first detected in the United Kingdom has now been discovered in Mexico.

The strain, called B117, was confirmed in a 56-year-old foreign citizen who had traveled from Amsterdam to Mexico City on Dec. 28, and then to the northeastern city of Matamoros the following day. The individual was asymptomatic when he arrived in the country, according to Mexico's director general of epidemiology, Jose Luis Alomia Zegarra.

After testing positive for COVID-19, the man was admitted to a Mexican hospital last week where he remains intubated, Zegarra said.

Genomic sequencing of the patient's sample that tested positive for COVID-19 revealed its B117 lineage. More than 500 suspected cases of the U.K. variant have been tested in Mexico, but this is the country's first verified case, according to Zegarra.

Mexican health authorities are tracking contacts of the patient, including people who traveled on the same flight. Two individuals who showed symptoms have since tested negative for COVID-19, while another 31 are asymptomatic and remain in isolation. Officials have been unable to locate 12 others, Zegarra said.

The highly contagious strain has become prevalent in London and other parts of southeast England, after first being identified in the English county of Kent in September. The B117 variant has since been detected in over a dozen other countries.
