Key points

  • Wearing a mask and washing hands are effective ways to prevent COVID-19 infection — but not everyone knows how to wash their hands properly.
  • Handwashing should take more than 20 seconds.
  • The demonstration uses black paint: palm against palm, then fingers interlaced, then palm against the back of the hand, repeated on both sides.
  • To do it better still, rub each finger separately, then the thumb, and finally the wrist.
  • After all these steps the whole pair of hands is thoroughly washed.
