COVID-19 updates: US has 1st day since November with fewer than 100K new cases

Delta will offer vaccinations to Georgia employees who are 65 and older starting on Monday, a company spokesperson confirmed to ABC News.

A health care provider will administer the vaccines in a section of the Hartsfield-Jackson Atlanta International Airport (Concourse C) and space at the Delta Flight Museum from Feb. 8 to Feb. 14. Delta's headquarters are located in Atlanta.

Delta CEO Ed Bastian said in a memo last week that 690 Delta employees had received at least one vaccination shot.

"We continue to work with federal and state authorities to prioritize immunizations for frontline Delta people," Bastian wrote in the memo. "While healthcare workers and our most vulnerable are already getting their shots, I strongly encourage each of you to get vaccinated when your time comes."

The number of COVID-19 vaccinations around the world now surpasses infections, Dr. Tedros Adhanom Ghebreyesus, director general of the World Health Organization, said during a Friday news briefing. "In one sense, that is good news and a remarkable achievement in such a short time frame."

On the other hand, he noted, those vaccinations have not been distributed equally.

"More than three quarters of those vaccinations are in just 10 countries that account for almost 60% of global GDP," Tedros said. "Almost 130 countries with 2.5 billion people [have] yet to administer a single dose. Some countries have already vaccinated large proportions of their population who are at lower risk of severe disease or death.”

Tedros urged drug companies to share their technology and data to ensure more equitable access.

"The longer it takes to vaccinate those most at risk everywhere, the more opportunity we give the virus to mutate and evade vaccines," Tedros said. "Unless we suppress the virus everywhere we could end up back at square one."

People with certain chronic conditions will be eligible for COVID-19 vaccinations on Feb. 15, Gov. Andrew Cuomo announced during a Friday press conference. Underlying conditions are a key risk factor for severe COVID-19 illness and death. Cuomo posted the full list of conditions on Twitter Friday afternoon, which included people with cancer, heart conditions, chronic kidney disease, severe obesity and those who are pregnant.

States that instituted mask mandates reported a decline in COVID-19 hospitalizations, according to a new report from the Centers for Disease Control and Prevention.

Researchers analyzed hospitalization data in 10 states with mask mandates between March and October of last year. They found a 5.5% decline in weekly COVID-19 hospitalizations among adults, compared to the period before the mandates were implemented.

In addition to reducing virus exposure and transmission, masks are part of a multi-pronged strategy to "reduce strain on the health care system," the researchers note, adding that masks likely have a direct effect on COVID-19 illness and death.

The researchers did not examine whether other policies, such as school closings and physical distancing recommendations, contributed to the decline. The results were published Friday in the CDC's Morbidity and Mortality Weekly Report.
