JetBlue Is First Airline to Mandate Face Coverings for Passengers
Face coverings will have to be worn by all passengers flying with JetBlue as of May 4, making it the first major U.S. airline to implement the precaution.
"Wearing a face covering isn't about protecting yourself, it's about protecting those around you," said Joanna Geraghty, JetBlue's president and chief operating officer, CNN reported.
"This is the new flying etiquette. Onboard, cabin air is well circulated and cleaned through filters every few minutes but this is a shared space where we have to be considerate of others. We are also asking our customers to follow these CDC guidelines in the airport as well."
JetBlue already requires all crew members to wear face coverings while on the job.
Meanwhile, American Airlines said Tuesday that flight attendants will have to wear face masks during every mainline and regional flight, CNN reported.
Also, American Airlines and United Airlines said they'll offer face masks for passengers beginning in May, but a United Airlines spokesperson said passengers won't be required to wear them.
On Tuesday, it was announced that three major New York City area airports will restrict terminal access to ticketed passengers, airport employees and others who need to enter the airport for business, CNN reported.

Trump Orders Meat Processing Plants to Stay Open
An executive order mandating that U.S. meat processing plants remain open during the coronavirus pandemic was signed Tuesday by President Donald Trump.
The order classifies meat processing as a critical infrastructure and is an attempt to prevent a shortage of meat in stores, the Associated Press reported.
The move jeopardizes lives and places more importance on cold cuts than workers' health, according to unions representing plant employees.
More than 20 U.S. meatpacking plants have closed temporarily, including two of the nation's largest, and production has slowed at others due to workers becoming ill or staying home to avoid getting sick, the AP reported.

Coronavirus Found In Airborne Droplets
Scientists have found the new coronavirus in tiny airborne droplets in two hospitals in Wuhan, China, which adds to growing evidence that it can spread through the air.
Previous laboratory experiments made the same finding, but this is the first time the coronavirus was found in airborne droplets in real-world settings, The New York Times reported.
It's not known if the coronavirus in the droplets was infectious, according to the study published this week in the journal Nature.
Such tiny droplets are expelled by breathing and talking and can remain in the air and be inhaled by other people, the Times reported.

Researchers Report First U.S. Dog With Coronavirus
A pet dog that's part of a Duke University study is believed to be the first in the United States to test positive for the new coronavirus.
The dog is a pup named Wilson who belongs to a family in Chapel Hill, NC. The mother, father and son in the home also tested positive for the coronavirus, but another family dog and cat didn't test positive, CBS News reported.
The family also has a lizard, which wasn't tested.
"To our knowledge, this is the first instance in which the virus has been detected in a dog. Little additional information is known at this time as we work to learn more about the exposure," Dr. Chris Woods, the lead investigator of the Molecular and Epidemiological Study of Suspected Infection (MESSI), said in a statement to CBS News.
Last month, health officials in Hong Kong said a coronavirus patient's pet dog tested positive for the virus and was likely the first case of human-to-animal transmission.
Since then, there have been several suspected cases of coronavirus reported in cats, but research suggests that dogs have low susceptibility to the virus, according to CBS News.
