Coronavirus updates: 84% of California population to go on lockdown Sunday night

The United States saw another record day of COVID-19 hospitalizations, according to the COVID Tracking Project, a volunteer-run effort to track the U.S. outbreak.

The group said the country currently has 96,039 people hospitalized with the disease, with a seven-day average of 91,331.

"Hospitalizations have doubled since November 1 and tripled since October 1. We should see 100k hospitalizations in the next couple of days," The COVID Tracking Project wrote on its Twitter account Monday night.

The group called November the "worst month of the pandemic outside of April," as the nation recorded a record 4.28 million new cases of COVID-19, over 72,000 new hospitalizations and 36,256 new deaths.

President Donald Trump’s coronavirus adviser Dr. Scott Atlas resigned on Monday.

Atlas, a neuroradiologist with no background in infectious diseases who had supplanted Dr. Anthony Fauci and other top federal public health officials as one of Trump's top medical advisers, was reaching the end of his 130-day term as a “special government employee,” according to the official.

Fox News, where Atlas first caught Trump’s eye before the president appointed him to a paid advisory role in the White House, initially reported the news.

Atlas spoke with the president Monday, a White House official confirmed to ABC News.

Atlas did not respond to a request for comment.

Miami-Dade County Mayor Daniella Levine Cava, who assumed office less than two weeks ago, announced Monday that she has tested positive for the coronavirus.

Her husband, Dr. Robert Cava, also tested positive and was exposed to the virus by one of his patients last Wednesday, according to the mayor. The couple is currently quarantining, the mayor said.

"We both remain in good spirits and are fortunate to have only mild symptoms at this time," Mayor Cava said in a statement.

Cava, a former Miami-Dade County district commissioner, was elected as the city's first female mayor on Election Day and assumed office on Nov. 17.

The county has over 229,000 total COVID-19 cases and at least 3,835 total deaths, according to the Florida Health Department.

California Gov. Gavin Newsom tweeted Monday that the state will receive 327,000 doses of the Pfizer COVID-19 vaccine.

"Transparency, equity, and safety will continue to be our top priorities as we begin the distribution process for Phase 1," Newsom tweeted.

The pharmaceutical company announced earlier this month that its vaccine was more than 95% effective in its Phase 3 trial. The vaccine is given in two doses over three weeks, according to Pfizer.

Pfizer has asked the Food and Drug Administration for an emergency use authorization and a public hearing to address the request has been scheduled for Dec. 10.

The agency could make its official authorization decision shortly thereafter.
