A pandemic of the novel coronavirus has now infected more than 75.5 million people worldwide and killed over 1.6 million of them, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Another 15,800 to 27,700 COVID-19 deaths are expected in the U.S. by Jan. 9, according to a forecast released by the Centers for Disease Control and Prevention.
This would bring the nation’s pandemic death toll to between 357,000 and 391,000.

The grim milestone came hours after the country reached new record highs in daily deaths, cases and hospitalizations.
A staggering 3,656 American deaths were reported on Wednesday -- resulting in an average of two deaths every minute in the last 24 hours.
Across the nation, 17,581 COVID-19 deaths were reported in the last week, more deaths that any other week since the start of the pandemic.
The U.S. is now averaging more than 2,500 reported deaths a day, according to a seven-day average, increasing by nearly 120% in the last month.
There are currently 113,069 people hospitalized with COVID-19 across the country, according to the COVID Tracking Project, marking the eleventh consecutive day that the nation has hit a record high of current hospitalizations. There are now nearly 40,000 more Americans currently hospitalized than one month ago.

At the Food and Drug Administration's Vaccines and Related Biological Products Advisory Committee Thursday on meeting about a potential recommendation of an emergency use authorization of Moderna’s vaccine, officials discussed concerns over anaphylactic reactions to Pfizer's vaccine.
Dr. Doran Fink, deputy director-clinical of the Division of Vaccines and Related Products Applications at the FDA, highlighted the two cases of allergic reactions -- one of which was anaphylaxis -- in health workers in Alaska on Wednesday.
Last week, in the U.K., there were also two cases of anaphylaxis after the Pfizer vaccine was administered. As a result, prior to emergency authorization, the FDA clarified its guidance, saying it is safe for people with any history of allergies, but not for those who might have a known history of severe allergic reaction to any “ingredient” of the vaccine.
Fink said the FDA anticipates there may be more reports of allergic reactions to the vaccines, and they will be investigated as they occur.
The FDA is coordinating with the Centers for Disease Control and Prevention to further investigate cases in the U.S. The FDA is also working with Pfizer to further revise the fact sheets and prescribing information for the vaccine to highlight CDC guidelines for post-vaccination monitoring and management of allergic reactions.
Fink noted that this “revision will be in addition to the information already included in the contraindications and warnings, including the facilities where vaccines are being administered should ensure that medical treatment for managing serious allergic reactions is immediately available.”
Fink said the same recommendations will be done for the Moderna vaccine, if it is authorized for use under an EUA.
