The public service announcement, which was resurfaced this week by the Nelson Mandela Foundation, shows the late activist and former South African president using soap and water while instructing the boy to wash and rinse thoroughly.
"While we continue to deliver safe water and sanitation to all our people, only you can protect yourself through good hygiene," the PSA's narrator says.
"Everybody should practice good hygiene," Mandela continues.
The Centers for Disease Control and Prevention recommends thorough and frequent handwashing as a way to protect oneself from a COVID-19 infection.
Use soap and water for at least 20 seconds, especially after you have been in a public place, the CDC advises.
