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.

The Los Angeles County Fire Department (LACoFD) saw its COVID-19 testing positivity rate fall significantly after 75% of firefighters on the force received their first COVID-19 vaccine.

When the first vaccines were being rolled out in late December, weekly LACoFD positivity rates reached 18%, roughly equivalent to positivity rates in the county's general population. Today, after three-quarters of the force opted to get vaccinated, the LACoFD positivity rate has fallen to 5.6%.

"As expected, the vaccine began to have its impact seven to 10 days after the first vaccines were given," Dr. Clayton Kazan, the department's medical director, said in a statement. "This is the first time in the entire pandemic that our data diverged from that of the county," he added.

This week, firefighters will start receiving their second dose of the two-dose vaccine.

Dr. Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, took aim at rich countries hoarding the COVID-19 vaccine and the pharmaceutical companies profiting off of it, during a WHO executive board meeting Monday.

"It’s right that all governments want to prioritize vaccinating their own health workers and older people first,” Tedros said. "But it’s not right that younger, healthier adults in rich countries are vaccinated before health workers and older people in poorer countries."

Tedros pointed to one of the lowest income countries in the world, which he did not name. "Just 25 doses have been given," he said. "Not 25 million, not 25,000 -- just 25. I need to be blunt: The world is on the brink of a catastrophic moral failure."

The deals rich countries have made with vaccine producers are putting the effectiveness of COVAX, the WHO's global vaccine-sharing program, at risk by driving up prices, according to Tedros. "This could delay COVAX deliveries and create exactly the scenario COVAX was designed to avoid, with hoarding, a chaotic market, an uncoordinated response and continued social and economic disruption," he added.

Disneyland Paris, which was slated to reopen Feb. 13, will delay reopening until April 2, 2021, "due to the prevailing conditions in Europe," Disney said in a statement posted on Twitter Monday.

As of now, Disneyland Paris is taking reservations from April 2 onward. Those with existing bookings between Feb. 13 and April 1 should consult Disney's website. "Given the current context our plans continue to evolve," according to Disney.

There were 174,513 new cases of COVID-19 confirmed in the United States on Sunday, according to a real-time count kept by Johns Hopkins University.

It's the first time in two weeks that the country has logged under 200,000 newly confirmed infections in a 24-hour reporting period. Sunday's tally is far less than the country's all-time high of 302,506 new cases on Jan. 2, Johns Hopkins data shows.

An additional 1,723 fatalities from COVID-19 were registered nationwide on Sunday, down from a 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 23,936,772 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 397,600 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 topping 300,000 on Jan. 2.
