In 2017, Vietnamese artists Min x Erik released a song called "Ghen" to YouTube. It was a pretty popular song. Everyone know "Ghen", the Vietnamese word for jealous. The song was written by Khắc Hưng. It's a catchy song about... well, jealousy.
Fast forward to 2020. The Vietnam National Institute of Occupational and Environmental Health (NIOEH) were looking to commission a song that would help Vietnamese people learn how to stop the spread of Coronavirus, as it was called at the time (it became better known as COVID-19). The timeline to write and record this was short.... so Khắc Hưng just went back to his old catalog and put new lyrics on his well-known song. Hence, "Ghen Cô Vy", or jealous coronavirus.
The song and accompanying dance challenge were a worldwide hit. And who can blame people for loving this? It's darned catchy. And, even if you don't know Vietnamese 1) turn on the subtitles, because you'll find it's been translated into many languages 2) the video will give you a good idea as to what's going on here.
Of course, you could also listen to the English translation.
