For months, misinformation about the novel coronavirus and vaccines has spread on social media — including about the meaning of the name assigned to the disease caused by the virus: COVID-19. 

Back in March, we debunked a claim that it “literally stands for Chinese Originated Viral Infectious Disease.”

Now, a new Facebook post claims that COVID-19 means: “Certificate of identification of vaccination with artificial intelligence.”

The post is wrong. 

The 2019 novel coronavirus was first reported in Wuhan, China, on Dec. 31, 2019. 

On Feb. 11, the World Health Organization announced that the name for the disease would be COVID-19 and the complete official name for the virus that causes the disease would be “severe acute respiratory syndrome coronavirus 2” or “SARS-CoV-2.” 

Until that point, the virus and the infection had been referred to as the “2019 novel coronavirus” or “2019-nCoV.”

“Having a name matters to prevent the use of other names that can be inaccurate or stigmatizing,” tweeted Tedros Adhanom Ghebreyesus, director-general of the WHO.

COVID-19 is an abbreviation of “coronavirus disease 2019,” the CDC says. “CO” stands for “corona,” “VI” stands for “virus” and “D” stands for “disease.” 

The number 19 reflects the year it was identified — 2019.
