Coronavirus updates: US will soon have 'half a million' deaths, CDC says

U.S. President-elect Joe Biden has chosen Dr. David Kessler, former commissioner of the Food and Drug Administration (FDA), to help lead the federal government's COVID-19 vaccine initiative.

Kessler, a pediatrician and lawyer who headed the FDA from 1999 to 1997 under the Bush and Clinton administrations, will replace Dr. Moncef Slaoui, who is the current chief science officer to Operation Warp Speed.

Biden also announced several other appointees who will join his incoming administration's COVID-19 response team.

"We are in a race against time, and we need a comprehensive strategy to quickly contain this virus," Biden said in a statement Thursday. "The individuals announced today will bolster the White House’s COVID-19 Response team and play important roles in carrying out our rescue plan and vaccination program. At a time when American families are facing numerous challenges I know these public servants will do all that is needed to build our nation back better."

There were 5,534 newly confirmed cases of COVID-19 and a record 81 deaths from the disease registered in Moscow on Thursday, according to Russia's coronavirus response headquarters.

In total, the Russian capital has reported 882,962 confirmed cases with 12,322 deaths, according to the coronavirus response headquarters.

With more than 3.4 million confirmed cases, Russia has the fourth highest cumulative total in the world, after the United States, India and Brazil, according to a real-time count kept by Johns Hopkins University.

There were 229,386 new cases of COVID-19 confirmed in the United States on Thursday, according to a real-time count kept by Johns Hopkins University.

It's the 10th consecutive day that the country has reported more than 200,000 new cases. Thursday's tally is less than the country's all-time high of 302,506 newly confirmed infections on Jan. 2, Johns Hopkins data shows.

An additional 3,769 new deaths from COVID-19 were registered nationwide on Thursday, down from a peak of 4,462 fatalities logged on Jan. 12, according to Johns Hopkins data.

COVID-19 data may be skewed due to possible lags in reporting over the holidays followed by a potentially very large backlog.

A total of 23,314,238 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 388,705 have died, according to Johns Hopkins data. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.

Much of the country was under lockdown by the end of March as the first wave of pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up over the summer.

The numbers lingered around 40,000 to 50,000 from mid-August through early October before surging again to record levels, crossing 100,000 for the first time on Nov. 4, then reaching 200,000 on Nov. 27 before topping 300,000 on Jan. 2.

Los Angeles' Dodger Stadium will open as one of the largest mass vaccination sites in the country on Friday, officials announced.

The stadium will have the capacity to vaccinate 12,000 people a day, LA Mayor Eric Garcetti said during his COVID-19 briefing Thursday.

Eligibility in Los Angeles County currently is limited to health care workers and seniors in nursing facilities.

The vaccination push comes as 1 in 3 people in LA County has been infected with COVID-19, Garcetti said. The county reported 17,323 new cases on Thursday.

"Our numbers remain very high. We remain one of the epicenters of this disease across the country," Garcetti said, though he added that there are signs that hospitalizations may be stabilizing.
