After dropping its mask mandate, Delta Air Lines spurred further controversy over an announcement, later amended, in which it referred to COVID-19 as having transitioned to an ordinary seasonal virus.

There is an ongoing controversy around changing COVID-19 policies. The Centers for Disease Control and Prevention had a mask mandate for air travel. Several major airlines, including Delta, Alaska Airlines, United Airlines, Southwest Airlines, American Airlines, and JetBlue Airways, dropped their own mask requirements.

The New York Times reporter initially posted a picture of the original post.

Delta's initial statement said they were relieved to see the U.S. mask mandate lifted to facilitate global travel. The company's statement was edited Tuesday, and the comment about the ordinary seasonal virus was removed and replaced with a more manageable respiratory virus with better treatments, vaccines and other scientific measures to prevent serious illness.

White House Assistant Press Secretary Kevin Munoz added a link to President Joe Biden's plan to fight carbon dioxide.

The COVID-19 virus will fade into a pattern of seasonal outbreaks according to experts. According to the Centers for Disease Control and Prevention, COVID-19 is different from the seasonal flu because it spreads more easily and can cause more serious illnesses in some people.
