The United States will remain a member of the World Health Organization, Dr. Anthony Fauci, the nation's top infectious disease expert, announced Thursday.

Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, made the announcement via video link to the WHO's executive board in Geneva, a day after Joe Biden was sworn-in as the 46th president of the U.S.

"I am honored to announce the United States will remain a member of the World Health Organization," Fauci told the board Thursday, adding that the U.S. will also "fulfil its financial obligations" to the WHO and stop reducing its staff at the United Nations agency..

Fauci, who is Biden's chief medical adviser on the coronavirus pandemic, also announced that the president will issue a directive Thursday that shows the country's intent to join the COVAX Facility, a global initiative to ensure rapid and equitable access to COVID-19 vaccines for all countries regardless of income.

Within hours of becoming president, Biden had signed an executive order reversing former President Donald Trump's decision to withdraw from the WHO. Trump had accused the organization of failing to correctly respond to the coronavirus pandemic and of allegedly giving too much power to China.

There were 178,255 new cases of COVID-19 confirmed in the United States on Wednesday, according to a real-time count kept by Johns Hopkins University.

The latest daily case count is far less than the country's all-time high of 298,031 newly confirmed infections on Jan. 2, Johns Hopkins data shows.

An additional 4,231 fatalities from COVID-19 were registered nationwide on Wednesday, just under the peak of 4,462 new deaths on Jan. 12, according to Johns Hopkins data.

COVID-19 data may be skewed due to possible lags in reporting over the holiday weekend and earlier holidays.

A total of 24,438,720 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 406,147 have died, according to Johns Hopkins data. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.

Much of the country was under lockdown by the end of March as the first wave of pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up over the summer.

The numbers lingered around 40,000 to 50,000 from mid-August through early October before surging again to record levels, crossing 100,000 for the first time on Nov. 4, then reaching 200,000 on Nov. 27 before nearing 300,000 on Jan. 2.

Rochelle Walensky, the new director of the Centers for Disease Control and Prevention who began her role after U.S. President Joe Biden's inauguration Wednesday, released a statement saying she is extending the eviction ban due to the ongoing COVID-19 pandemic.

"As a protective public health measure, I will extend the current order temporarily halting residential evictions until at least March 31, 2021," she said in the statement. "The COVID-19 pandemic has presented a historic threat to our nation’s health. It has also triggered a housing affordability crisis that disproportionately affects some communities."

She said that as cases continue to rise, it's important to "keep people in their homes and out of congregate settings — like shelters — where COVID-19 can take an even stronger foothold."

An additional 450 deaths from COVID-19 were reported in Texas on Wednesday, marking a new record for the Lone Star State, according to data from the Texas Department of Health.

There were also 25,512 newly confirmed cases of COVID-19 and 5,017 probable cases reported Wednesday.

The cumulative totals now stand at more than 2.1 million confirmed and probable cases, including at least 32,844 deaths, according to the state health department data.

Shortly after U.S. President Donald Trump announced his administration would be lifting COVID-19 travel restrictions for the United Kingdom, Brazil and much of Europe, President-elect Joe Biden's team said that would not be the case.

Biden's incoming White House press secretary, Jen Psaki, said the new administration doesn't intend to lift the travel restrictions next week.

"With the pandemic worsening, and more contagious variants emerging around the world, this is not the time to be lifting restrictions on international travel," Psaki wrote on Twitter late Monday. "On the advice of our medical team, the Administration does not intend to lift these restrictions on 1/26. In fact, we plan to strengthen public health measures around international travel in order to further mitigate the spread of COVID-19."

Trump issued a proclamation earlier Monday night, announcing he will rescind entry bans imposed because of the coronavirus pandemic on most non-U.S. citizens arriving from Brazil, the United Kingdom and much of Europe.

The travel restrictions were put in place last year toward the beginning of the pandemic, following calls from health officials who urged the president to stop the spread of the novel coronavirus.

The proclamation said the entry bans will be removed starting Jan. 26, the same day that all travelers must present a negative COVID-19 test or proof of recovery from the disease in order to enter the United States. Biden and his administration will be sworn in Wednesday.

"Public health officials in the jurisdictions have a proven record of working with the United States to share accurate and timely COVID-19 testing and trend data, and the United States has active collaborations with the jurisdictions regarding how to make travel safe between our respective countries," the proclamation states.
