December 21 coronavirus news

Virgin Atlantic will require proof of a negative Covid-19 test for all passengers traveling from London to the United States starting December 24, the company said in a statement.

The United Kingdom is currently grappling with what appears to be a more infectious variant of the coronavirus, which has resulted in new restrictions in the south of England and numerous countries cutting off travel from the UK, including most of its European neighbors.

The Australian state of New South Wales reported eight new locally-transmitted Covid-19 cases from Monday following almost 45,000 tests being carried out.

That's the lowest number of new local cases since a mystery outbreak sprang up in Sydney's Northern Beaches area last week.

Seven of the eight new local cases are linked to the Sydney cluster, NSW Health said Tuesday, and the eighth is still under investigation. The total number of cases from the cluster now stands at 90.

The state saw a record number of Covid-19 tests reported to 8 p.m. last night, with 44,466 tests carried out on Monday, NSW Health added.

NSW reported 18 total new cases, the other 10 being imported from travelers in hotel quarantine.

Mystery cluster: Health authorities in New South Wales have acted quickly to get on top of the new cluster, which ended a run of days with no community transmission in Sydney.

The Northern Beaches municipality, with a population of just over 250,000, has been locked down until Wednesday night in an attempt to stop the spread.

NSW has recorded a total of 4,600 Covid-19 cases since the pandemic began.

The United States reported 115,351 current Covid-19 hospitalizations on Monday, setting a new record high since the pandemic began, according to the Covid Tracking Project (CTP).

This is the twentieth consecutive day that the US has remained above 100,000 current hospitalizations.

The highest hospitalization numbers according to CTP data are:

There have been at least 18,006,061 cases of coronavirus in the United States and at least 319,190 people have died from Covid-19, according to data compiled by Johns Hopkins University. 

It took the US 284 days to reach 9 million Covid-19 cases, according to university data. It only took the nation 52 days to reach the second 9 million cases.

Johns Hopkins recorded the first case of coronavirus in the US on Jan. 21. 

Operation Warp Speed has delivered more than 4.6 million vaccines to all 50 states, Washington, DC, and Puerto Rico, and 614,117 people have received the shot as of 9 a.m. Monday morning, according to the US Centers for Disease Control and Prevention’s Covid Data Tracker.

The total doses distributed are cumulative counts of Covid-19 vaccine doses that have been recorded as “shipped” in the CDC’s Vaccine Tracking System since Dec. 13, the agency reported Monday.

The total number of administered doses are reported to the CDC from state, territorial and local public health agencies and five federal agencies, including the Bureau of Prisons, the Veterans Administration, the Department of Defense, the Department of State and Indian Health Services.

The numbers of vaccines shipped account for both Pfizer/BioNTech and Moderna, but the number of doses administered includes only Pfizer’s vaccine at this time, the CDC said.

Pfizer’s vaccine started rolling out on Dec. 14 and Moderna’s, which just received an emergency use authorization from the US Food and Drug Administration Friday, started shipping out Monday.

Massachusetts reported 3,760 new Covid-19 cases and 41 deaths on Monday, according to the Massachusetts Department of Public Health. 

The state currently has a seven-day average positivity of 5.94%, according to the health department's Covid-19 dashboard.

Note: These numbers were released by Massachusetts' public health agency and may not line up exactly in real time with CNN’s database drawn from Johns Hopkins University and the Covid Tracking Project.

Connecticut's hospitalizations and positivity rate are moving downward, according to Gov. Ned Lamont at a news conference on Monday.

Hospitalizations are continuing to trend downward and are currently at 1,143, which is 24 less than what they were on Friday. The positivity rate is 5.18% and was at 6.85% on Friday. 

Lamont also reported 4,595 new Covid-19 cases and 95 new deaths. 

A total of 7,761 doses of the Covid-19 vaccine have been administered in the state so far, Lamont said.

Moderna vaccine deliveries will begin in the state starting today, he said. 

Note: These numbers were released by the state Connecticut and may not line up exactly in real-time with CNN’s database drawn from Johns Hopkins University and the Covid Tracking Project.

British Airways and Delta Airlines have agreed to test all passengers before they enter New York state, Gov. Andrew Cuomo announced Monday afternoon.

Cuomo also asked Virgin Atlantic to join those airlines in voluntary testing passengers before boarding flights to New York.

The news comes after a new Covid-19 variant was reported in England, prompting some countries to ban travel from the United Kingdom.

Remember: There is no evidence the new coronavirus variants are any more virulent, meaning they do not cause more severe disease. They do not appear to impact the effects of treatments or the protection offered by vaccines.

President-elect Joe Biden received the first dose of his Covid-19 vaccine in Newark, Delaware, Monday afternoon during a live televised event.

Biden's wife, Jill, was by his side.

The President-elect received the vaccine at ChristianaCare’s Christiana Hospital and it was administered by Tabe Mase, nurse practitioner and head of Employee Health Services.

When Biden was asked by Mase if she wanted him to count to three before administering the shot, he said, "No, you just go ahead any time you're ready."

Correction: The name of the facility where Biden received the vaccine was ChristianaCare’s Christiana Hospital in Newark, Delaware. The shot was administered by Tabe Mase.
