After the UK hit a record 218,724 cases in 24-hours, Prime Minister Boris Johnson promised action to plug staffing gaps in the worst-hit areas, including drafting medical volunteers backed by army support.
The United States, the United Kingdom, France, and Australia have all reported record daily COVID-19 cases, as the WHO warned on Tuesday of the emergence of newer, more dangerous variants with rapidly spreading Omicron.
Britain breached 200,000 cases for the first time on Tuesday, Australia posted almost 50,000 and France registered more than 270,000, all three countries easily topping their previous records.
But dwarfing even those numbers was the 1,080,211 reported by the United States on Monday, a global record.
The country’s Monday figures are usually higher due to delays in weekend tallying — and were likely inflated further after a three-day New Year’s holiday weekend.
The rolling average over seven days — which experts see as more reliable — was 486,000 cases per day as of Monday evening, Johns Hopkins University said.
The heavily mutated Omicron variant, the most transmissible to date, accounted for around 59% of US cases near the end of last year.
Omicron’s rates of deaths and hospitalisations have been lower across the world, raising hopes the virus could be evolving into a relatively benign seasonal illness.
But the World Health Organization in Europe sounded an ominous note of caution on Tuesday, warning the soaring infection rates could have the opposite effect.
"The more Omicron spreads, the more it transmits and the more it replicates, the more likely it is to throw out a new variant," WHO senior emergencies officer Catherine Smallwood told AFP in an interview.
"Now, Omicron is lethal, it can cause death... maybe a little bit less than Delta, but who’s to say what the next variant might throw out," she added.
"Even in well-capacitated, sophisticated health systems there are real struggles that are happening at the moment."
‘War footing’
Such a scenario was feared in Britain, where the government said Tuesday that hospitals have switched to "war footing" due to staff shortages.
After the UK hit a record 218,724 cases in 24-hours, Prime Minister Boris Johnson promised action to plug staffing gaps in the worst-hit areas, including drafting medical volunteers backed by army support.
Johnson also defended his decision not to increase restrictions over Christmas in England — unlike in other parts of the UK — and ruled out another nationwide lockdown.
Australia, which had previously successfully suppressed infections for much of the pandemic, also smashed its previous caseload record with 47,738.
The surging infections have driven a rush on increasingly scarce self-administered rapid antigen kits and created hours-long queues at centres providing more reliable PCR tests.
"I think at this point we all know somebody who has either got Covid or we have got coworkers off work because they are quarantining or isolating," Australia’s deputy chief medical officer Sonya Bennett said.
Cyprus also posted a new record of 5,457 cases on Tuesday and now has the highest infection rate per capita, according to AFP figures.
Wealthy nations have rushed to give their population third booster shots to counteract the rising cases, while many in poorer nations have not yet been able to receive a first.
Ahead of the pack, Israel began rolling out fourth doses last week. Prime Minister Naftali Bennett said Tuesday that a small Israeli study indicated that fourth coronavirus vaccinations increased antibodies "fivefold".
More restrictions
In China, which has pursued a "zero Covid" approach, just three asymptomatic cases prompted 1.2 million people in the central city of Yuzhou to be confined to their homes.
Daily infections have hit a two-month high in the Philippines, which will expand restrictions in Manila from Wednesday to include more than 11 million people living near the capital.
Omicron is also fuelling surging cases in India, where authorities said the capital will lockdown over the weekend.
The sprawling megacity’s new restrictions came the same day as its chief minister, Arvind Kejriwal, announced he had been infected and was suffering "mild symptoms".
Also testing positive on Tuesday were Sweden’s king and queen, as well as Mauritanian President Mohamed Ould Ghazouani, none suffering serious symptoms.
Omicron has also sent the sports world — only just back on its feet after previous Covid restrictions — reeling, with many leagues forced to cancel or postpone games.
Tennis world number Novak Djokovic — who has repeatedly refused to confirm whether he has been vaccinated — said Tuesday that he was heading to the Australian Open after being granted a medical exemption.
