U.S. Surgeon General Jerome Adams tweeted Thursday morning that his wife had been admitted to a hospital because of complications with her cancer treatment. He said he wasn’t allowed to visit her because of COVID-19-related restrictions.

Adams’ wife, Lacey Adams, was first diagnosed with metastatic melanoma in 2018.

“I’m hoping she doesn’t have to spend New Year’s in a hallway because the beds are full,” Adams tweeted.

At least 342,734 lives have been lost to COVID-19 in the U.S., representing approximately 18.9% of the total global death toll of 1.8 million people.

One in every 965 Americans has now died from the virus, according to ABC News’ of data compiled by the COVID Tracking Project.

The U.S. death toll is 114 times the total lives lost on Sept. 11, 2001, and just over half the total number of deaths that were recorded in U.S. during the 1918 influenza pandemic.

At least 19.7 million Americans have tested positive for COVID-19 in the 345 days since the Centers for Disease Control and Prevention confirmed the first U.S. case on Jan. 21.

That means about 1 in every 16 Americans has contracted the virus.

The oldest resident of Massachusetts, 112-year-old Hazel Plummer, received her first dose of the vaccine on Wednesday.

Plummer was among the 49 residents and 50 employees at the Life Care Center of Nashoba Valley, a nursing home in Littleton, Massachusetts, to do so.

The Life Care Center of Nashoba Valley suffered from the coronavirus outbreak in the spring but “was free of COVID-19 by the end of May,” the facility said.

In Wuhan, China, where COVID-19 was first identified in December 2019, small crowds gathered to take in a fireworks display and ring in 2021.

Wuhan was the first epicenter of the pandemic, but the central Chinese metropolis of 11 million emerged out of lockdown in mid-April and has not had a reported case since May.

In New York City, no New Year’s revelers will be gathering in Times Square to watch the ball drop this year.

New York City Mayor Bill de Blasio said this is "the most moving New Year's Eve," but urged New Yorkers to "watch on TV. Don't go down there."

Kentucky Gov. Andy Beshear spoke out Monday after Walgreens stores in Louisville and Lexington, Kentucky, gave COVID-19 vaccines to members of the general public.

Beshear said at a press conference that last week, the pharmacies were left with extra doses of the vaccine after administering it to long-term care facilities, so, they offered the leftover doses to average citizens. This, the governor said, does not follow government protocol, as the vaccine is not yet being given to the general public.

"I don't think that this was intentional, and we have to understand that in an undertaking this massive that mistakes are going to happen," Beshear said. "I believe that here a mistake happened in the thawing, but the reaction wasn't what it should've been."

In a statement, Walgreens said that per the Centers for Disease Control and Prevention's guidance, Pfizer’s COVID-19 vaccine can be at refrigerated temperatures for only five days, so, to avoid wasting doses of the valuable vaccine after giving it to at-risk adults in long-term care facilities, they used the leftover doses they had on residents.

The doses were offered to local first responders, Walgreens pharmacy and store team members and residents of the community, many of whom were over age 65, Walgreens said.

"These measures were taken to ensure every dose of a limited vaccine supply was used to protect patients and communities," the company added. "We will utilize excess vaccine inventory in priority patient populations and continue to work closely with state and federal health agencies in our efforts to vaccinate residents in long-term care facilities and ensure requested doses meet their needs."
