More than 117,000 confirmed cases of COVID-19 among children were reported in the United States last week, representing a 10% increase in cases between Jan. 21 and Feb. 4, according to a report released Monday by the American Academy of Pediatrics and the Children's Hospital Association.

The report, which compiles state-by-state data on infections among kids, found that 2.9 million children have tested positive for COVID-19 nationwide since the start of the pandemic. In total, children represent 12.9% of all cases in U.S. states that report COVID-19 data by age.

Facebook announced Monday a global campaign to promote authoritative COVID-19 sources and push back on disinformation.

The effort will including helping people find out where and when to get vaccinated, expanding the social media company's efforts to remove false COVID-19 information from Facebook and Instagram, and giving $120 million in advertising credits to health ministries, NGOs and UN agencies.

Facebook also said it would provide data for education to help build trust in COVID-19 vaccines, as well as to inform vaccine delivery efforts.

Ten percent of Americans, or 31.6 million people, have received one or more doses of the COVID-19 vaccine, according to a U.S. Department of Health and Human Services planning document obtained by ABC News.

Three percent of the population, or 9.1 million people, have gotten both shots of the two-dose vaccine, according to the document.

U.S. President Joe Biden has pledged to get 100 million shots into Americans' arms during the first 100 days of his presidency. Since his Jan. 20 inauguration, 24.6 million doses have been administered.

U.S. Rep. Ron Wright, R-Texas, died Sunday after contracting COVID-19 last month, his office confirmed in a statement Monday.

Wright, who had lung cancer, was diagnosed with the disease on Jan. 21 and admitted to Baylor Hospital in Dallas. He was 67.

"Over the past few years, Congressman Wright had kept a rigorous work schedule on the floor of the U.S. House of Representatives and at home in Texas’ Congressional District 6 while being treated for cancer," his office said.

Wright is the second American lawmaker to die after testing positive for COVID-19. Luke Letlow, Louisiana's incoming Republican congressman, died at age 41 in late December, just days before he was due to be sworn in.

Grocery store and meatpacking workers said they still feel just as vulnerable to contracting COVID-19 now as they did at any point during the pandemic. In an organized call, the United Food Commercial Workers union called for hazard pay and that food service workers be prioritized for the vaccine.

At least 137 grocery workers and 132 meatpacking workers have died from COVID-19, according to the call.

Guidelines from the Centers for Disease Control and Prevention say that front-line essential workers, like grocery store employees, should be prioritized for the vaccine. But not every state has done so and union officials said their workers still can't get the vaccine even when it's being offered at the pharmacy in the store where they work every day.

"What is inexplicable, given the threats and the risks that these essential workers face and the fact that a new report, it shows only 13 states currently prioritize access for food workers, which puts our food supply at risk,” said UFCW President Marc Perrone.
