Dr. Anthony Fauci and Republican Kentucky Sen. Rand Paul engaged in a heated exchange at a Tuesday Senate hearing on COVID-19.

When Paul claimed Fauci was attacking scientists who disagreed with him, Fauci responded, "you keep distorting the truth."

"I brought together a group of people to look at every possibility with an open mind ... you're completely turning it around," Fauci said.

Fauci said the purpose of the committee was to get help to the American public, but he said Paul instead chooses to "keep coming back to personal attacks on me that have absolutely no relevance."

Fauci told the Senate committee on Health, Education, Labor and Pensions that Paul's attacks are "for political reasons" and inspire "the crazies out there."

Fauci referenced the December arrest of a California man who, at a traffic stop, was allegedly found with an AR-15 style rifle, loaded magazines, boxes of ammunition and body armor. Prosecutors said the driver downloaded TikTok videos, compiling a list of people he allegedly wanted to kill, including Fauci and former Presidents Bill Clinton and Barack Obama.

The U.S. daily death average from COVID-19 is steadily rising, with an average of 1,550 new fatalities each day -- up by about 44% since Christmas, according to federal data.

This average is still significantly lower than last winter when the nation peaked at about 3,400 deaths per day.

Indiana now has the nation's highest death rate, followed by Delaware and Wyoming.

Nearly 146,000 Americans with COVID-19 are currently in hospitals -- a pandemic high -- according to new data from the Department of Health and Human Services.

On average, more than 18,500 virus-positive Americans are being admitted to the hospital each day, a figure which has more than doubled over the last month. It's still not clear how many COVID-19-positive people in hospitals were admitted to the hospital for the virus or admitted for other reasons and coincidentally tested positive.

About 30% of hospitals (with available data) are facing critical staffing shortages.

With 48,686 New Yorkers testing positive on Monday, the state saw a case drop for the first time in weeks, Gov. Kathy Hochul announced.

Hochul called this "a glimmer of hope," but warned, "we are not at the end."

While hospitalizations continue to rise, "the rate of increase is slowing, and to us that is very encouraging," the governor said.

Uganda reopened its schools to students on Monday after nearly two years, ending the world's longest school closure due to the coronavirus pandemic.

Schools across the East African nation of 44 million people have been fully or partially closed since March 2020, when the pandemic began. The closures affected more than 10 million learners, according to data from the United Nations Educational, Scientific and Cultural Organization (UNESCO).

Save the Children welcomed the reopening of Uganda's schools but warned that "lost learning may lead to high dropout rates in the coming weeks without urgent action."

The London-based charity revealed in a report last November that up to one in five children in low-income countries, including Uganda, had dropped out of school due to rising poverty, child marriage and child labor, which have been exacerbated by the pandemic. In a statement Monday, Save the Children warned of "a 'second wave' of dropouts as returning students who have fallen behind in their learning fear they have no chance of catching up."

To tackle the potential crisis in Uganda, Save the Children has launched "Catch-up Clubs," which assess children and teaches them at the required level to help them regain literacy and other learning, with child protection support and cash assistance for families struggling to send them to school.

"As schools begin to reopen across the country, it is critical that all girls and boys have access to the support they need to successfully return to the classroom," Edison Nsubuga, head of education at Save the Children in Uganda, said in a statement Monday. "Many children have fallen behind in school as a result of the COVID-19 pandemic. Children who are behind in their learning are less likely to unlock their potential as adults. However, when children receive the learning boost they need and have access to quality education, they can reach their full potential."
