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."

New York has become the fourth state to cross 1 million COVID-19 cases, the governor announced Saturday.

New York joined California, Texas and Florida in hitting that mark. Illinois, at over 975,000 cases, is likely to join those four in the coming days. California has already crossed 2 million cases.

"With 2020 now behind us, we can see brighter days ahead, but to get there quickly, it's going to take all New Yorkers staying smart and staying united," Gov. Andre Cuomo said in a statement. "We have the vaccine, and that is good news, but it will be months before we've reached critical mass, making it as important as ever that we do not let COVID fatigue get the best of us."

The state reported just over 15,000 new cases on Saturday and a percent-positivity rate that has grown to 7.45%. That number was around 1% for much of the summer after being the epicenter for the pandemic in the spring.

There was some good news on Saturday as Cuomo reported there were 72 fewer people hospitalized due to the virus in the state.

Officials continue to fear growing cases in the new year after Christmas and New Year's travel in recent weeks. New York crossed 30,000 deaths earlier this week.
