When mucus or droplets containing the virus enter the human body through the eyes, nose or throat, it can cause the spread of respiratory viruses such as the virus that causes COVID-19. Communication is often achieved by hand. The hands are also one of the most common channels through which the virus spreads from person to person.
During the global pandemic of the disease, frequent hand washing with soap and running water is one of the most economical, simple and most important ways to prevent the spread of the virus.
You need to know the following about proper hand washing:
How to wash hands properly?
Rubbing and rinsing in a hurry will not remove all the viruses on your hands. Here are the steps to achieve effective hand washing:
Wet hands with running water;
Use plenty of soap on your hands;
Carefully rub all parts of your hands, including the back of your hands, between your fingers and between your nails, for at least 20 seconds;
Rinse the foam with running water;
Dry your hands with a clean cloth or disposable towel.
How long is it appropriate to wash your hands?
Each hand wash should last at least 20 to 30 seconds. You can use some simple timing methods, such as singing “Happy Birthday Song” twice.
The use of hand sanitizer should also follow the same time principle, that is, use a hand sanitizer with an alcohol content of not less than 60% and wipe your hands with it for at least 20 seconds to ensure that all parts of your hands are covered.
When should I wash my hands?
In order to prevent COVID-19, make sure to wash your hands at the following times:
After blowing your nose, coughing or sneezing;
After using public transportation, going to public spaces such as markets or religious places;
After touching the surface of objects outside the home, including after touching banknotes;
Before, during and after caring for the patient;
Before and after meal.
In general, you should always wash your hands at the following times:
After going to the toilet
Before and after meal
After touching garbage;
After touching animals or pets;
After changing baby diapers or helping children go to the toilet;
When the hands are visibly dirty.
Which is better to wash your hands with soap or with a wash-free lotion?
Whether you are washing your hands with soap and running water or using hand sanitizer, as long as you operate or use it correctly, you can usually kill most bacteria and pathogens effectively. It is often more convenient to use hand sanitizer when you are away from home, but its price may be higher and it is difficult to buy in an emergency. In addition, although alcohol-based hand sanitizers can kill the coronavirus, they cannot kill all types of bacteria and viruses. For example, it is relatively ineffective against norovirus and rotavirus.
What else can I do to help stop the spread of the virus, in addition to washing my hands?
Pay attention to hygiene when sneezing and coughing: When sneezing or coughing, cover your mouth and nose with a bent elbow or a tissue, properly dispose of the used tissue, and then wash your hands;
Avoid touching your face (especially the mouth, nose and eyes);
Maintain social distancing: avoid shaking hands, hugging or kissing others; avoid sharing food, utensils, cups and towels;
Avoid close contact with anyone who has cold or flu-like symptoms;
If you or your child has symptoms such as fever, cough or difficulty breathing, please seek medical advice promptly;
Clean the surfaces that the virus may touch. Clean the surface of various objects more frequently than usual, especially in public places.
