Blend of kung fu + flu, in reference to the disease's presumed origin in Wuhan, China, in late 2019.
Particularly in the United States, the use of Kung Flu and similar terms became associated with President Trump after he coined the phrase to pin the blame for the spread of COVID-19 on the Chinese government. Critics, including the Chinese government, have said these terms were racist, stigmatizing, and part of a strategy to minimize the threat posed by the coronavirus.
