The United States topped 12 million cases of Covid-19 on Saturday, as the third wave's uncontrolled spread prompted the Centers for Disease Control and Prevention to urge Americans not to travel for Thanksgiving.

The country recorded more than 200,000 coronavirus cases over the last 24 hours, bringing the total to 12,002,863, according to NBC News' tally.

"If you are planning to spend Thanksgiving with people outside your household, we urge you to reconsider," they said.

During a call on Thursday with reporters, Erin Sauber-Schatz with the CDC said that in the last week the United States had over a million new cases of Covid-19.

Less than a week ago, the country had recorded 11 million total cases.

In the last week we've seen over a million new cases Thanksgiving is a week away," said Sauber-Schatz, head of the CDC's Community Interventions and Critical Populations Task Force.

Henry Walke, the CDC's Covid-19 incident manager, said the agency is not mandating that Americans spend the holiday at home, but recommending it.

Meanwhile, China's President Xi Jinping said Saturday that the country is ready to step up global Covid-19 vaccine cooperation
