Step One: Apply the sanitizer to one palm.
Step Two: Rub both palms together.
Step Three: Rub product over your hands until dry.
The post says: “The C.D.C. method takes 35 seconds on average to complete; the alternative, 42.5 seconds.”
According to the post, this is the WHO way:
Step One: Rub palms together.
Step Two: Rub each palm front to back over the back of the other hand, interlacing fingers.
Step Three: Twist palms with fingers interlaced, and rub between fingers.
Step Four: Interlock your fingers, (thumbs should be on opposite sides), and twist again, this time, backs of fingers against palms.
Step Five: Clasp your left thumb in your right hand and move thumb in circular motion — then switch thumbs.
Step Six: (Still with us?) Press your right fingers together and rub them in a circular motion on your left palm, then switch. You’re done!
I have noticed here that even if the hands are washed properly, dirty towels are used to dry them off.
This leads to: "back to square one." It is just like have safe drinking water in a container, and leaving the container uncovered.
