" 'Wash your hands' thoroughly. To prevent the spread of cholera bacteria, you should follow proper hand hygiene. Follow the three minute rule when washing your hands. Start by wetting your hands and lathering them with soap. Rub your palms together and then rub the backs of each of your hands for at least 20 seconds. Clean the areas between your fingers and then work your way up to your wrists. Rinse your hands thoroughly with clean water and then pat them dry. This should all take about three minutes." nghĩa là gì?
