These days are still the peak of the outbreak. More and more people may have heard: there are suspected or confirmed cases of this epidemic in nearby communities and even in their own communities.
How do you protect yourself and your family in this situation? What’s worth noting?
To this end, we have collected readers’ questions and summarized 10 selected questions from them to answer them.

1. Is there any risk of infection by taking the elevator? How to prevent it?
There are risks, but they can be prevented.
“Pneumonitis diagnosis and treatment plan for new type of coronavirus infection (trial version 4)” states that the new type of coronavirus is mainly transmitted by “droplet transmission” and “contact transmission”.
Elevators are confined and confined environments. If they take the same elevator with a virus carrier, they may be infected by droplets caused by their cough, sneeze, and speech.
If the droplet falls on the button or wall, it may spread to the next person through contact. If he touches his mouth, nose or eyes with his hands, he may be infected.
But don’t worry, want to prevent, remember three words: wear a mask and take the elevator, do not touch your face with your hands, wash your hands when you get home.
The popular tissue bag fingers in the circle of friends is also a good way.

Special attention is required: do not touch the contaminated surface with the wrapped paper or masks; if so, wash your hands with soap and running water for 20 seconds as soon as possible.
2. What about public facilities such as stair handrails and community equipment?
Similarly, viruses may attach to the surfaces of these public facilities and spread through contact.
In a word, do n’t touch it if you ca n’t touch it. If you really touch it, do n’t touch your nose, mouth and eyes, please wash your hands immediately.
3. There are confirmed cases in the neighborhood. Is it safe to use public toilets?
Basic security, but there are details to pay attention to.
There may be contact transmission in public toilets, although everyone in the toilets do n’t want to touch anything … but sometimes it is inevitable that clothes will get around and touch the toilet ring. At this time, extra hand washing and clothes should be done. Disinfection work.
Also, droplets may spread in public toilets. Wear a mask.
4. How many days can the new coronavirus persist in these in vitro environments?
The virus can survive in vitro for some time, but it is not necessarily contagious.
The current lack of understanding of the biological characteristics of new coronaviruses requires further study.
Based on the biological characteristics of the highly similar SARS virus:
-
It can be used on the surface of various objects such as plastic, glass, mosaic, metal, cloth, copy paper, etc.Survive 2 to 3 days;
-
It can survive in urine at room temperature of 24 ℃ for at least 10 days.
However, survival does not necessarily mean infectious.
Research has shown that if droplets containing high concentrations of SARS virus fall on water-absorbent materials, (such as Dry paper, cotton cloth) , no longer contagious within 5 minutes; if it falls on non-absorbent material (such as plastic, waterproof jacket) < / span>, it takes 1 hour.

5. The droplets may fall on the hair after going out. Will the virus be brought to the bed if I do not wash my hair at night?
Don’t worry too much.
Based on the research conclusion that “SARS virus can survive on plastic, glass, mosaic, metal, cloth, copy paper and other surfaces for 2 to 3 days”, we speculate that the virus may also live on hair for 2 to 3 days. .
Because hair is a “non-absorbent material”, it is speculated that virus-containing droplets will not be contagious for more than an hour.
So you do n’t have to worry too much about getting into the bed, but for insurance reasons …
Too lazy to wash your hair or wear a hat, remember to disinfect the hat accordingly.
6. Will the garbage used in the suspected / diagnosed cases in the community cause infection?
It is possible, but the chance is very small. The rubbish used by virus carriers can basically be transmitted to the next person only through contact.
So our prevention advice is:
➊ Wash your hands carefully at all times, or bring a bottle of alcohol-free hand sanitizer;
➋ Do n’t touch anything suspicious;
➌ When throwing garbage, if you must lift the garbage cover, please bring a disposable glove;
➍ Masks you have used, please consciously seal them and classify them as hazardous waste;
➎ Warmly remind the cleaning staff to take precautions.
7. When the sun comes out, can I bask? Is there a risk of contamination?
Don’t worry about contamination when drying the quilt.
According to the “environmental viability of coronavirus” research, it is shown that under the combined effects of dryness, heat, ventilation, and ultraviolet light, the activity and survival time of the virus will decrease in the sun.
8. Why ventilate? Will the virus come into the house with dust?
Because ventilation can reduce the virus concentration in the room.
The virus has a survival time of at least 2 to 3 days. It can gradually accumulate indoors and increase the indoor virus concentration. On the other hand, not only the space is large, but also the ultraviolet rays, and the virus concentration is relatively low.
9. How should my clothes be disinfected after going home?
Generally, as long as you are not in contact with dangerous people, you can change your clothes normally. If you are really worried, you can also choose to disinfect the coat with alcohol. If there is no alcohol, 70% to 75% alcohol is also possible.
Fold the sterilized jacket and fold it in half with the inside facing outward and place it on the porch.
Special reminder: Alcohol spray is flammable and explosive! Stay away from kitchens and flames!
10. In addition to alcohol, what other methods can be used to disinfect clothes?
With reference to previous research on SARS virus, there are several ways to disinfect clothes:
➊ Appropriate temperature (56 ～ 75 ℃) and time (30 ~ 90 minutes) dryer;
➋ Irradiate with UV lamp for 60 minutes;
