What are the problems in 0 1' s outing activities and how to prevent them?
First, taking the elevator risks infecting novel coronavirus, but it can be prevented.
According to the Diagnosis and Treatment Plan for Infected Pneumonia in novel coronavirus (Trial Fourth Edition), novel coronavirus is mainly transmitted by droplets and contact.
The enclosed elevator is a closed and narrow space. If you take the same elevator as a virus carrier, you may be infected by droplets from coughing, sneezing and talking.
If these water drops on the elevator button or the wall, they may spread to the next person through contact. And if it happens that the next person touches his mouth, eyes or nose, he may be infected.
However, this is not without preventive measures. The way is: wear a mask in the elevator, don't touch your face with your hands, and wash your hands when you go home.
In addition, the popular way of "wrapping fingers with paper towels" on the Internet is also a good method!
However, it should be noted that the paper wrapped by your fingers and the mask you wear may have novel coronavirus. Please do not touch the contaminated surface. If you accidentally touch it, wash your hands with soap and tap water for more than 20 seconds as soon as possible.
In addition to closed elevators, the same is true of public facilities such as escalators, stair handrails and fitness equipment in the community. They may all be infected with the virus and pass it on to the next person through contact.
So, again, don't touch it if you can; If you really accidentally touch it, don't touch your eyes, nose or mouth. If you still accidentally touch it, remember to wash your hands immediately.
Second, there are confirmed cases nearby, and it is basically safe to use public toilets.
Although it is basically safe to use public toilets in this case, there are still some problems to pay attention to.
There may be contact transmission in public toilets. And everyone will inevitably encounter clothes rubbing against the surrounding walls and touching the toilet seat. At this time, it is necessary to do one more job of washing hands and disinfecting clothes.
In addition, there are many people in public toilets, so it is necessary to wear masks.
Third, novel coronavirus can survive in vitro for a period of time, but it is not necessarily contagious.
Because of the lack of understanding of the biological characteristics of novel coronavirus at present, if we refer to the biological characteristics of SARS virus which is highly similar to it, we can speculate:
Novel coronavirus can live on the surface of plastic, glass, mosaic, metal, cloth, copy paper and other objects for 2-3 days. Novel coronavirus can live in urine for at least 10 days at room temperature of 24 degrees Celsius.
However, survival does not necessarily mean infectivity. Studies have shown that if the liquid containing high concentration of SARS virus drops on absorbent materials, such as dry paper and cotton cloth, it will no longer be contagious within 5 minutes; If it falls on non-absorbent materials, such as plastic, waterproof clothing, etc. It takes an hour.
Problems that should be paid attention to after going out and going home.
First, there may be droplets with virus falling on your hair after going out, which is not dangerous.
According to the research conclusion that SARS virus can survive for 2-3 days on the surface of plastic, glass, mosaic, metal, cloth, copy paper and other objects, it is speculated that novel coronavirus may also survive for 2-3 days on his hair.
However, because the hair is a non-absorbent substance, it is speculated that the virus-containing droplets are not contagious when they are on the hair for more than 1 hour.
Therefore, don't worry too much about bringing the virus to bed when you go out, but if you really don't want to wash your hair, it's safer to wear a hat when you go out. However, remember to disinfect the hat when you go home!
Second, how to disinfect the clothes you wear after going home?
Under normal circumstances, as long as you don't touch dangerous people, these clothes only need to be replaced normally. But if you really don't feel at ease, you can also choose to spray alcohol on your clothes for disinfection. If there is no alcohol at home, choose 70%~75% alcohol.
Disinfected clothes had better be turned over and folded in half, with the inside facing outwards, and put on the porch.
It should be noted that alcohol spray is flammable, remember to stay away from the kitchen and flames!
Then, some people may ask, is there any other way to disinfect clothes besides alcohol?
Actually, there is!
For example, using a dryer, the temperature (56~75 degrees Celsius) and time (30~90 minutes) are appropriate;
For example, irradiation with an ultraviolet lamp for 60 minutes;
For example, soak in chlorine-containing disinfectant for 5 minutes;
For example, ventilate in the natural environment outside the window for 3 days and dry in the sun for more than 60 minutes.
In addition, it should be noted that the steamer is not recommended because its temperature and market are not up to standard. Chlorine-containing disinfectants are also easy to buy: 84 disinfectant, bleaching powder and the like.
But parents who have pets such as cats and dogs at home need to pay attention. Disinfectant is toxic to these animals, so check the information in advance when you use it at home to avoid cats and dogs touching these disinfectants!
If a confirmed case is found in the community, can you still open the window for ventilation?
The answer is yes. Of course, you can open the window for ventilation, because ventilation can reduce the concentration of indoor viruses.
We already know that the virus has a survival time of at least 2~3 days, during which it can gradually accumulate indoors and increase the concentration of indoor virus. The outdoor space is not only large, but also full of ultraviolet rays, and the virus concentration is relatively low.
So, do you understand? Although the epidemic is severe, don't panic, let alone scare yourself. In this case, keep a good attitude, go to official channels to learn more about prevention knowledge, do a good job of protection, wear a mask, wash your hands frequently, go out less, keep a distance from people, and open more windows for ventilation. I believe we can overcome the epidemic!
