Chapter 22 Washing hands for no less than 20 seconds

Dr. Philip, director of the Department of Clinical Microbiology at New York University Central Hospital, pointed out that there are also many bacteria in the working environment of the office.There are also many germs on telephones, computer keyboards, mice, coffee machines, and elevator buttons. Influenza viruses, staphylococci, and E. coli are the most common germs.

The most contacted part of the human body and the environment is the hand, and the hand is also the most susceptible to infection with germs.If you don't wash your hands carefully, you can bring germs into your body when you touch your mouth, nose, eyes or eat.

People's first line of defense against germs is washing their hands.According to the survey, less than 50% of people wash their hands after going to the toilet, and they are often perfunctory when washing their hands.The correct procedure is to scrub thoroughly after applying soap, and carefully wash the crevices of fingers, knuckles and nail crevices, and the time should not be less than 20 seconds.In addition to proper hand washing, work areas, phones, desks, computer keyboards and mice should be cleaned frequently.
