COVID-19 (the 2019 coronavirus) does not mean that there were earlier numbered versions, but there are jokes.
 
“I would love to know who took COVID-1-18” was posted on Twitter by Justin Stangel on February 11, 2020. “Does someone want to ask what happened to Covid 1-18?” was posted on Twitter by Ghostzilla later on February 11, 2020.
