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

More people in the United States died of COVID-19 in the past week than they did from the flu during all of last season, data show.

There were an estimated 22,000 flu deaths nationwide during the 2019-2020 flu season, according to the U.S. Centers for Disease Control and Prevention. The flu season was regarded as moderate and stretched out over several months.

By contrast, there were 23,119 new COVID-19 deaths reported between Jan. 6-12, according to The COVID Tracking Project.

There were 4,056 deaths due to COVID-19 reported on Tuesday in the U.S., according to The COVID Tracking Project.

That marks the second time new deaths surpassed 4,000, based on the tracker's tally, following the record 4,081 reported less than a week ago on Jan. 7.

The seven-day average number of deaths reported Tuesday also set a new record, the tracker said.

There were 213,885 new cases and 131,326 people are currently hospitalized due to the virus in the U.S.

Deaths from COVID-19 in the United Kingdom have jumped, as the country battles a new, more contagious variant of the novel coronavirus.

The U.K. reported 6,298 new COVID-19 deaths in the week ending Jan. 10, up from 4,165 the previous week, according to the World Health Organization's latest epidemiological report. There were 9.3 new deaths per 100,000 residents -- a 51% increase over the previous week, according to the WHO.

Elsewhere, the African region reported the highest percentage increases over any other region in cases and deaths during that time frame. There were over 174,000 new cases and over 4,300 new deaths, according to the report.

COVID-19 cases are on the decline in India, the second-most populous nation in the world. There were just over 126,000 new cases reported -- a 7% decrease in infections per 100,000 residents over the previous week, according to the report.

Beginning Jan. 26, those flying to the U.S. from foreign countries must follow new rules that were announced by the Centers for Disease Control and Prevention on Tuesday.

Passengers must take a COVID-19 test “within the 3 days before their flight to the U.S. departs, and provide written documentation of their laboratory test result (paper or electronic copy) to the airline or provide documentation of having recovered from COVID-19,” the CDC said.

“Airlines must confirm the negative test result for all passengers or documentation of recovery before they board,” the CDC said. “If a passenger does not provide documentation of a negative test or recovery, or chooses not to take a test, the airline must deny boarding to the passenger.”

The CDC also asks travelers “to get tested again 3-5 days after arrival and stay home for 7 days post-travel.”
