The U.S. is forecast to have almost 500,000 COVID-19 deaths by mid-February.
A pandemic of the novel coronavirus has now infected more than 94.2 million people worldwide and killed over 2 million of them, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
President-elect Joe Biden got his second dose of the two-dose Pfizer/BioNTech vaccine on Monday in Newark, Delaware.
After two doses, the Pfizer vaccine is 95% effective.
U.S. Rep. Bonnie Watson Coleman, D-N.J. announced Monday that she has received a positive result for COVID-19 from a rapid antigen test and is awaiting results from a polymerase chain reaction (PCR) test.
Coleman said she was forced to shelter in place with unmasked colleagues last week when a mob of President Donald Trump's supporters stormed the U.S. Capitol building in Washington, D.C.
"Following the events of Wednesday, including sheltering with several colleagues who refused to wear masks, I decided to take a Covid test," Coleman, 75, wrote on Twitter. "I have tested positive."
The congresswoman, who previously received one dose of the Pfizer/BioNTech vaccine, said she is experiencing mild, cold-like symptoms and is isolating at home.

Japan has identified a new variant of COVID-19, Dr. Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, said during a Monday news conference.
Japanese health officials alerted the WHO of the new variant, which is different than COVID-19 variants first identified in the U.K. and in South Africa, over the weekend. High transmission of the virus in much of the world is giving it more chances to mutate and evolve into new variants.
"Most notably, transmissibility of some variants of the virus appears to be increasing," Tedros said. "This can drive a surge of cases and hospitalizations, which is highly problematic for health workers and hospitals already close to breaking point," he added.
"At present, the variants do not seem to show increased severity of disease," Tedros said.

COVID-19 killed more law enforcement officers in the line of duty than anything else in 2020, according to a new report.
The National Law Enforcement Officers Memorial Fund report found that 145 of the 264 federal, state, military, tribal and local law enforcement officer deaths last year were related to COVID-19, with that number expected to rise as more deaths from the virus are confirmed. Other officer fatalities in 2020 included car crashes, heart attacks, stroke and firearm deaths.
Last year marked the highest number of line-of-duty law enforcement deaths since 1974.
