The US counted a record number of daily coronavirus deaths Thursday at nearly 4,000, according to data from Johns Hopkins University.
The 3,998 deaths were recorded over the 24-hour period ending at 8.30pm local time (0130 GMT Friday), during which the US notched 265,246 new infections, according to the university.
Sharp rises in cases around the world have led authorities to impose a slew of new lockdowns and other restrictions, even as dozens of countries roll out the first stages of the vaccination campaigns hailed as the light at the end of the tunnel.
The plight of countries struggling to control the virus matters beyond their borders, said the International Federation of Red Cross and Red Crescent Societies.
“The fact is that no one is safe until we are all safe,” it said.
“The nature of this virus means that the world can only be as strong as the weakest health system.”
The global outbreak shows no signs of abating, with nearly 1.9 million people known to have died worldwide and 87 million confirmed cases.
