Washington, The Covid-19 situation is exploding at an unprecedented speed and could alter daily life for millions of Americans during the first month of the New Year, the media reported on Sunday.

The number of one day case additions has increased 219 per cent since December 27, when New York reported an addition of 26,737 cases.

"Omicron is truly everywhere. What I am so worried about over the next month or so is that our economy is going to shut down, not because of policies from the federal government or from the state governments, but rather because so many of us are ill," Dr Megan Ranney, a professor of emergency medicine at Brown University's School of Public Health, was quoted as saying in the report.

The US continues to be the worst-hit country with the world's highest number of cases and deaths at 54,859,966 and 825,816, according to the Johns Hopkins' Center for Systems Science and Engineering (CSSE).

In Ohio, Governor Mike DeWine has announced the deployment of about 1,250 National Guard members as hospitals struggle with staffing shortages.

According to FlightAware, a flight-tracking website, 2,311 flights entering, leaving or within the US were cancelled as of 7.30 a.m. on Saturday, and another 424 flights were delayed.
