NEW YORK • The United States recorded its 12th million Covid-19 case on Saturday, even as millions of Americans were expected to travel for the upcoming Thanksgiving holiday, ignoring warnings from health officials about furthering the spread of the disease.
More than 12,010,000 cases of the coronavirus have been reported, according to a Reuters tally of public health data, capping a series of days with record-breaking infections, with the Midwest experiencing one of the most dramatic increases in cases per capita.
The Covid-19 pandemic has claimed more than 255,000 lives in the US - more than in any other nation - according to the Reuters tally, and the recent escalation has prompted over 20 states to impose sweeping new restrictions this month to curb the virus.
Reuters data shows the pace of new US infections has quickened, with nearly one million more cases recorded in just the last six days before the latest record.
This compares with the eight days it took to get from 10 million cases to 11 million, and the 10 days it took to get from nine million to 10 million.
More than one million people flew through US airports last Friday, according to data from the Transportation Security Administration (TSA), fuelling fears of even greater spread of the virus.
Bloomberg reported that according to TSA data, a total of 1,019,836 people passed through US airport security screening portals last Friday, 40 per cent of the nearly 2.6 million who flew on the equivalent day last year. Friday's total was well above the one-week average of 829,000 passengers a day.
The increase came in spite of recent warnings from carriers, including American Airlines, United Airlines and Southwest Airlines, about softening holiday travel demand. The Thanksgiving period is usually one of the busiest for travel.
It was the second-heaviest domestic air traffic day since the start of the pandemic, despite pleas from health officials for Americans to stay home.
"This is the second time since the pandemic passenger volume has surpassed one million," TSA spokesman Lisa Farbstein wrote on Twitter on Saturday.
Last Friday marked another milestone in the US as the highest number of new Covid-19 cases was reported - 196,815 infections in a day.
Health officials have warned that the burgeoning wave of infections could soon overwhelm the healthcare system if people do not follow public health guidance, particularly around not travelling and mingling with other households for Thursday's traditional Thanksgiving celebration.
Still, video footage on Twitter showed more than a hundred people, wearing masks, crowding departure gates at Sky Harbor airport in Phoenix, Arizona, last Friday.
Lines for TSA checkpoints and kiosks at Chicago O'Hare airport were also long last Friday and "reminiscent of pre-pandemic times", local TV station WGN reported.
The number of Thanksgiving air travellers was expected to decline by 47.5 per cent from last year, but nonetheless, 2.4 million people were forecast to take to the skies, according to a report earlier this month from the American Automobile Association (AAA). It said the number travelling by car was expected to fall by only about 4 per cent.
"For those who are considering making a trip, the majority will go by car, which provides the flexibility to modify holiday travel plans up until the day of departure," AAA senior vice-president Paula Twidale said in a statement.
The US Centres for Disease Control has issued a "strong recommendation" to Americans to refrain from all kinds of travel over Thanksgiving.
"We're alarmed with the exponential increase in cases, hospitalisations and deaths," CDC official Henry Walke told reporters last Thursday.
Seven governors of Midwestern states - Wisconsin, Minnesota, Illinois, Ohio, Kentucky, Indiana and Michigan - encouraged their residents to heed medical advice over the holidays and not to celebrate Thanksgiving with people outside their households.
In a video message, the governors also referred to the recent announcement from Pfizer that its Covid-19 vaccine is more than 90 per cent effective. Pfizer said it would seek emergency-use authorisation of its vaccine from US regulators, the first such application.
"This is great news, but it doesn't mean we can let our guard down," Illinois Governor J.B. Pritzker said.
