Emirates, Etihad Airlines to test IATA COVID-19 travel pass
Emirates Airlines and Etihad Airways said they have partnered with the International Air Transport Association to trial IATA Travel Pass -- a mobile app that serves as a “digital passport” to verify pre-travel COVID-19 testing or vaccination status.
The app also helps passengers find information on travel and entry requirements at their destinations.
Emirates Airlines said it plans to roll out the first phase in April, during which passengers leaving Dubai can share their COVID-19 test status directly with the airline through the app before arriving at the airport. Etihad will first offer the travel pass on some flights out of Abu Dhabi in the first quarter of 2021.

U.S. death toll from COVID-19 surpasses 400,000
The U.S. death toll surpassed 400,000 on Tuesday and now stands at 400,022 fatalities.
The number of American lives lost to the coronavirus is more people than the number of U.S. soldiers who died in battle during World War I, World War II and the Vietnam War combined, according to a data estimate compiled by the Department of Veterans Affairs.
The U.S. death toll is roughly equivalent to the population of Tampa, Florida, or Tulsa, Oklahoma.
By the middle of February, "we expect half a million deaths" in the U.S. from COVID-19, Dr. Rochelle Walensky, who’s nominated to serve as the next director of the Centers for Disease Control and Prevention, told CBS’ "Face the Nation" on Sunday.

Norway says it 'can't rule out' vaccine side effects in 23 deaths
Twenty-three reports of suspected deaths associated with COVID-19 vaccines have been submitted to Norway's national health registry as of Jan. 14, according to an updated statement from the country's drug regulator on Monday.
The Norwegian Medicines Agency said it "cannot rule out that adverse reactions to the vaccine occurring within the first days following vaccination (such as fever and nausea) may contribute to more serious course and fatal outcome in patients with severe underlying disease."
Thirteen of those reports have been assessed by the drug regulator, as well as the Norwegian Institute of Public Health.
"The reports suggest that common adverse reactions to mRNA vaccines, such as fever and nausea, may have contributed to a fatal outcome in some frail patients," Sigurd Hortemo, chief physician at the Norwegian Medicines Agency, said in the statement.
Steinar Madsen, medical director of the Norwegian Medicines Agency, told the state-run broadcaster NRK: "We are not alarmed by this."
"It is quite clear that these vaccines have very little risk, with a small exception for the frailest patients," Madsen said. "Doctors must now carefully consider who should be vaccinated. Those who are very frail and at the very end of life can be vaccinated after an individual assessment."
Norway is currently administering COVID-19 vaccines to the elderly and people in nursing homes with serious underlying diseases -- at first with just the Pfizer/BioNTech vaccine up until Jan. 15, and then also with the Moderna vaccine. Official figures show that more than 30,000 people have received the first shot of the Pfizer or Moderna vaccines in Norway since the end of December.
According to the Norwegian Medicines Agency, an average of 400 people die each week in nursing homes and long-term care facilities nationwide.
The Scandinavian country of 5.3 million people has confirmed more than 58,000 cases of COVID-19 since the start of the pandemic, including at least 521 deaths, according to the latest data from the Norwegian Institute of Public Health.
