During an epidemic, it is best to use hand sanitizer or soap with germicidal and disinfectant properties, rinse under running water, and rub for no less than 20 seconds. It is also important to master the correct hand-washing steps: rub your palms relative to each other; cross your fingers and rub your palms against the back of your hands; cross your fingers and rub your palms relative to each other; bend your knuckles in your palms; rub your thumbs in your palms; rub your fingertips in your palms and then rinse well with water. After washing your hands, wipe them with disposable paper towels or clean towels. In addition, wash your hands regularly before meals, after defecating, after coming home from a trip, after touching garbage, after petting animals, and avoid touching your eyes, nose or mouth with your hands. If it is not convenient to wash your hands with water, you can also use a no-rinse hand sanitizer with alcohol content. Content source: Dr. You Lai
