On January 12, 2021, Shenyang Health Network published health information: “The prevention and control of the new coronavirus be the first person responsible for your health.”
The climate is getting colder and the low-temperature environment is more suitable for the survival of the new corona virus. Faced with the sudden and severe situation of epidemic prevention, each of us is primarily responsible for our own health. We must take personal precautions and standardize the prevention of epidemics.
To better understand the meaning of various epidemic prevention measures, let’s first understand the epidemic characteristics of the new coronavirus.
The source of infection of the new coronavirus are mainly patients infected by the new coronavirus and asymptomatic patients. Transmission methods include:
1. It is spread directly by respiratory droplets: Close contact with the droplets from sneezing, coughing and exhaled air from the patient can cause an infection.
2. Aerosol transmission: droplets mix in air to form aerosols. Prolonged exposure to high concentrations of aerosols in a relatively closed environment can cause infection.
3. Contact transmission: When droplets are deposited on the surface of the article, the article becomes contaminated, after touching it with the hands, touching the mouth, nose, eyes, etc. with your hands can cause infection. The crowd is generally touchy.
As for the source of infection, everything will be fine without contact with patients with new coronary pneumonia. Asymptomatic infections, contaminated items, and the environment are important factors in the spread of the new coronavirus. Therefore, it should not be taken lightly and the mentality of luck is not acceptable.
To cut the route of transmission, the use of masks, the hygiene of the hands, avoiding the close contact and getting along in closed spaces are important measures of prevention of epidemics.
Regarding the selection and precautions of masks, first of all, there are currently two types of masks that are clearly useful in preventing new coronavirus infections. One is clearly marked with “Medical Surgical Masks” on the outer packaging to prevent respiratory infections to some extent; the other is of type N95. The masks, without breathing valves, have a filtration efficiency of 95% to prevent infection by droplets; other types are useless, remember.
It should be noted that it is recommended to change the mask every 2-4 hours. Once contaminated, replace the mask as soon as possible; fold the side that touches the nose and mouth and put it in a clean self-adhesive bag when storing; elevators, shops in front of houses, public toilets, indoor places, hospitals and other places, do not remove the mask easily.
Question: What should I do if the use of masks and goggles fog up?
Answer: Apply a suitable amount of shower gel evenly on the lens and pat dry to prevent fogging. Place a napkin under the metal strip of the mask to increase the tightness of the mask and reduce water mist.
Question: What should I do if wearing a mask is prone to acne?
Answer: Please replace the mask in time when it is wet to avoid bacteria growth. If pimples appear, an antibiotic ointment can be used. If symptoms worsen, it is recommended to consult a doctor.
Regarding hand washing, after coughing and sneezing, before touching the mouth, nose and eyes, before and after preparing food, before eating, after using the toilet, after touching the environment of public goods , going out, before and after putting on and taking off masks, after handling animals, etc. are important times for hand washing. . Avoid touching your mouth, nose, eyes and other parts with your hands and foreign objects.
Hand washing method: seven-step hand washing method, see the picture below; use plain water, soap or hand sanitizer, etc.

When it is necessary to travel or work, avoid close contact and closed spaces; reduce contact with other people; reduce contact with surfaces in public areas, such as elevator buttons, etc., wash your hands after touching them; reduce transportation, etc.
After you return home, do a good job of disinfecting and protecting your home environment: 1. Open windows to ventilate at least twice a day, at least 30 minutes each time, and stay warm; 2. High frequency contact with door handles, switches, tables, chairs and faucets in the home.
