The epidemic in the United States continued to deteriorate. Various universities began to change their online courses, and classes in K-12 in Washington, New Jersey, Ohio and other states began to suspend classes. Today U.S. stocks melted again, which increased the public’s panic.
In the face of menacing viruses, how can we effectively protect them? At present, even in New York and California, where the epidemic is severe and densely populated, masks are rarely seen. One is that “a mask is hard to find”, and the other is that because of cultural differences, Americans do not wear masks when they are really sick.
Domestically, the importance of wearing masks has always been emphasized and the use of masks is mandatory; however, the US government suggests that unless you take care of a pneumonia patient or you need to wear a mask, you do not need to wear a mask but wash your hands!
1. How effective is hand washing in preventing the new crown?
Data show that people touch the face 23 times per hour on average, and 44% of them touch the mouth, nose, and eyes where infections are likely to occur.
It is easy for us to touch our faces inadvertently with our hands, to think about problems, itchy eyes, itchy noses, tidy up our hair, hold glasses … for children and people who have the habit of touching their faces, the frequency is much more.
Your hands will touch many surfaces, public transportation seats, armrests, door handles, keyboards, mobile phones, drinking fountains, etc., and they may be contaminated. Touching the face with hands contaminated will undoubtedly increase the risk of infection, and inadvertently become a medium of communication.
A variety experiment in Japan simulates the process of family contact transmission. It is assumed that my father has a virus at home (simulated with fluorescent powder) and lives normally without the knowledge of his family. After a period of time, the amount of virus on his face is detected (fluorescent powder) , 5 out of 6 people were infected (not including dad).
Although the simulation test is not rigorous, it can still reflect the importance of the process of virus transmission and hand washing.
After dad touches the door handle, the virus is passed on to the family; the child is lively and active, likes to rub his eyes and touch his face, the sister is used to tidying the hair, the virus on the face is most obvious; the mother coaxes the child; Rinse hands under hand, the virus on the face is least.
Washing your hands can indeed take away the virus on your hands. Washing your hands and not touching your face can effectively block the spread of contact. Wash your hands frequently, wash your hands properly, and wash your hands carefully.
Second, you need to know about hand washing, masks and gloves
1. Which one is more important, such as wearing a mask, gloves, and hand washing?
Patients spread through droplets, and masks are very important for those who have close contact with patients. How much the effect of wearing a mask on the public has not yet been confirmed by data. However, the incubation period of new coronary pneumonia is long and there is the possibility that it can spread without symptoms. This is probably the most important reason for mandatory masks in China. The World Health Organization believes that the protection of wearing only a mask is useless, and it is necessary to wash your hands when wearing a mask correctly. Especially for children, uncomfortable wearing a mask may make you want to touch your face with your hands, increasing the risk.
Similarly, wearing gloves sometimes increases the risk of exposure to the virus, giving people the illusion that they are not exposed to the virus, and relax their vigilance and directly touch the face with gloves.
Therefore, whether you wear a mask or not, it is very important to wash your hands often!
2. How to wash your hands correctly?
When hands are dirty, wash hands with soap and tap water.
When washing hands for 20 seconds, 2 birthday songs should not be accelerated manually;
Perfunctory hand washing and short hand washing time can not achieve the effect of sterilization;
Turn off the faucet with disposable wet tissues or elbows after washing hands;
Wash your hands and dry them in time. Wet hands are suitable for the survival of germs. Drops of water may also spread germs.
When conditions do not allow rinsing, use alcohol-based (at least 60%) hand sanitizer as an alternative to hand washing. Hand soap is sufficient, and scrub for 20-30 seconds.
3. In what situations do you need to wash your hands?
First, wash your hands before eating
Second, wash hands before and after going to the toilet (to change the habit of washing hands only after going to the toilet)
Third, wash your hands after sneezing
Other situations that require strict attention to hand washing: wash hands before and after visiting patients; wash hands before touching babies; wash hands if any other hands are contaminated
4. Wearing gloves can reduce the direct contact between hands and public goods, but still need to wash hands.
There is a virus risk in places where people gather in public transportation, shopping supermarkets, etc., and you can wear gloves for protection. It is recommended to use disposable gloves (or cleaned gloves), do not reuse them, take them off at home and wash your hands immediately.

3. What protection can be done in the US?
The public in the United States and European countries generally accepts that only people who are ill and medical staff wear masks. Officials also do not list masks as public protection measures. Nowadays, masks are scarce, and it is also a question whether they are available. If you have a mask, weigh the pros and cons and decide not to wear it yourself; if you do n’t have a mask, strict other measures can effectively reduce the risk.
In addition to masks, the daily protective measures we can do are:
1. Avoid close contact with sick people (6 inches);
2. Clean your hands frequently and wash your hands with soap and water for at least 20 seconds. If there is no soap and water, use a hand sanitizer containing at least 60% alcohol;
(Touch items in public places, after returning home, before contact with children and the elderly, before and after contact with patients, after coughing and sneezing, before and after meals, before handling ingredients, etc.)
3. Cover your mouth and nose with tissues and arms when you cough or sneeze. If you are an infected person (do not know who you are), this is very important to protect others.
4. Try to avoid touching your face, nose, eyes, etc. with your hands;
5. Avoid touching the surface of public places as much as possible, such as elevator buttons, door handles, handrails, etc. If you must touch, cover your fingers with paper towels or sleeves;
6. Home cleaning and disinfection: daily cleaning of frequently touched surfaces (tables, door handles, light switches, handles, desks, toilets, faucets, sinks, mobile phones, keys, etc.) About indoor disinfection: “epidemics” and flu current, Are you doing daily household disinfection correctly?
7. Avoid going to crowded and crowded places, people in the crowd are sick, crowded and closed environment will increase the risk of infection;
8. Cancel unnecessary travel, especially do not board the cruise. The “epidemic” in the United States is intensifying, effectively protecting children, and see if you do this?
