Covid news live: South Korea reports record daily cases, US to require vaccination proof at all border crossings


As cases begin surging once more in the US, millions of people are expected to travel for the Thanksgiving holiday, and health workers and hospital systems are now preparing for an influx of Covid patients after having little time to recover from the summer surge.

Last year, there was a major surge in cases around the holidays. But this year, new tools could blunt the spread – if they are taken up quickly.

US scientific agencies on Friday recommended boosters for all adults six months after mRNA vaccination, and children over the age of five recently became eligible for vaccines.

Existing treatments like monoclonal antibodies are highly effective if given early, while two promising antiviral medications from Merck and Pfizer may be authorized in coming weeks. But the new treatments may come against a backdrop of rising cases during the holiday season.

“It is a race against time,” Kyle Enfield, the associate chief medical officer of critical care at University of Virginia Health, said.

More than 92,000 Americans are now testing positive for Covid-19 each day, and more than 1,000 people are dying from the virus every day, according to the US Centers for Disease Control and Prevention. Cases are rising in a majority of states, with hotspots in the midwest, north-east and parts of the south-west.

Concerns have been raised that a lack of diversity among people participating in clinical trials means drugs and medical equipment may be less effective in certain groups.
