People around the world have been tasked with regular, thorough hand-washing to help mitigate the spread of the coronavirus.
In Vietnam, they are using music to teach just why hand-washing is so important, but also, the right way to do it.
A public service announcement from Vietnam's Health Ministry has caught on, racking up millions of views on YouTube.
Vietnamese dancer Quang Dang took the song to the next level. His choreography has carried the song to millions of additional viewers on the video app Tik Tok.
"The first one is you have to rub your hands like this. Rub your hands very easy, palm to palm," Quang Dang told CNN. "The second one is the back of this hand to the palm of the other hand. The third one is fingers interlaced...fingers interlaced."
