With the rapid development of the economy, the development trend of the world is also steadily advancing, and when everything is still proceeding in a stable and orderly manner, an outbreak of pneumonia at the end of 2019 completely disrupted people's lives. The cause of this pneumonia is different from the previous SARS, its virus strain is one of the coronavirus family, because no medical institution in the world has seen and studied the new virus, because it is named the new coronavirus.
Since the outbreak of the new crown pneumonia, all parts of the country have been actively preventing and controlling, and the vaccination of the new crown vaccine has also effectively curbed the mutation of the new crown virus in the human body. But even if people's protection is in place, this terrible virus is still constantly mutating, and its ability to spread is better than ever. In the case report, it is shown that the new crown pneumonia will be transmitted through aerosols, and even there are hidden dangers upstairs and downstairs, which can be said to be invincible, so what is the matter?
First, the spread of the new crown virus
In the early days of the outbreak of new crown pneumonia in Wuhan, the CDC had not yet figured out how it was transmitted exactly, and people could only carry out general epidemic prevention by washing their hands frequently and wearing masks. With the in-depth analysis of the case, the medical staff called on everyone to wear N95 masks, strictly follow the handwashing process, open more windows for ventilation and a series of activities, at that time, the understanding of the spread of the new crown virus only stayed on the transmission of severe influenza.
However, people's protective ability has been strengthened, the virus is also updated and upgraded in a timely manner, the speed of mutation is staggering, and now the harm to society is the result of step-by-step mutation and upgrading, and even his transmission ability and methods are endless. Before the advent of Omikeron, the main ways of spreading the new crown virus were as follows.
1. Direct transmission
It refers to the fact that people carrying COVID-19 may spread by sneezing or coughing, or by producing droplets when talking and talking, because of the proximity between several people. Studies have shown that the exhaled gas of the patient is infected by others, which can also cause people around them to become infected with the virus. In the early days of the COVID-19 outbreak, most people caused mass infections in this way, which is also the most vulnerable route to infection.
2. Indirect transmission
Although the virus cannot survive without the human body, the new crown virus has a super transmission ability in the process of fighting the human body, and it is not excluded that it will attach to the surface of the human body to produce indirect transmission. When a person carrying the virus touches the limbs of others, the virus may follow the movements of the hand into the mucous membranes such as the mouth, nose, and eyes, resulting in infection, which is also a way to be vigilant about transmission.
3. Mother-to-child transmission
Because the coronavirus is ultimately a virus, it also has most of the general routes of transmission, such as mother-to-child transmission. Mothers who test positive for COVID-19 may transmit the virus to their babies through the placenta, and the new crown virus may also replicate actively in placental cells.
4. Aerosol transmission
Compared to other modes of transmission, this route of transmission was the last to be discovered. In Ningbo, one case was infected after entering an underground parking lot without a mask while riding, and two other cases stayed in the parking lot during the same time period and did not wear a mask, which was judged to be an aerosol transmission causing infection. What's more, when a resident of Taierzhuang went outdoors to dig wild vegetables, he stayed with an asymptomatic infected person and was infected.
All of the above transmission routes are more conventional transmission methods, but aerosol transmission is a relatively strong transmission route that has just been discovered. In the face of an unfamiliar word, many people have certain misunderstandings, and even cause certain rumors, and even some people think that viruses are derivatives of the human body, which is actually incorrect. So what is aerosol transmission? If aerosol transmission had occurred, would Aumechon have been more dangerous?
Aerosol transmission is when droplets mix in the air to form an aerosol, which leads to infection when inhaled by a person. This is the case of digging wild vegetables, because someone has carried the virus to the place where wild vegetables have been dug, although the two people have not met, but the virus is suspended in the air has not been inactivated, and the person who digs wild vegetables may be infected by inhaling aerosol particles suspended in the air containing viruses, which is not common.
In fact, the main transmission channels of new crown pneumonia are still droplets and contact these two ways, aerosol transmission is essentially because of the spread of human droplets, although it is similar to the first two, but in fact, aerosols are actually included in droplet infection and contact infection, in the face of this form, people in life should also maintain extremely high vigilance, always do a good job of protective measures to ensure their health.
In the early days of the outbreak of new crown pneumonia, the strain of the virus has not yet mutated, and its lethality is not large. When injected with a vaccine for COVID-19, the body becomes immune, and people with COVID-19 will have symptoms of varying degrees, initially manifesting as fever or mild cough, but the mutated virus may cause shocks to the human body, further developing into pneumonia or causing death.
In the latest treatment manual issued by the National Health Commission, in addition to clarifying the transmission of respiratory droplets and contact transmission, it is also specially noted that the transmission routes such as aerosols and digestive tract have yet to be clarified. Although the official does not give a definite answer, there have been cases of unknown causes, and most people prefer to believe that they have no credibility, so we must be vigilant against this new type of transmission.
Second, will aerosol transmission make Aumequeron more powerful?
Omikeron is a mutated virus that spreads much faster and more harmfully than the original new coronavirus. According to the World Health Organization's investigation report, the new crown virus variant, Omicron, remains dangerous, especially for those who have not been vaccinated against COVID-19. The highly contagious variant of the new coronavirus, Omiljung, may have become the virus that infected the largest number of humans at the same time in modern human history.
That is to say, Omikeron itself is a very dangerous virus, even if it is not combined with aerosols, it has a great spread intensity. When the first outbreak of Omiljung in South Africa triggered a large group of concentrated infections, the Hong Kong Institute for Disease Control and Prevention also found that the vertical transmission risk of Omiljung was extremely large, and its invisibility was particularly strong. The infection of the man who dug up wild vegetables with Omicron, while seemingly unreasonable, was also a fact.
Now that the way aerosols are transmitted has been confirmed, does that mean that the virus is suspended everywhere in the air? The answer is no, aerosols are mostly produced by patients when they cough and sneeze, and are essentially the spread of droplets. Therefore, the staff doing nucleic acid testing outdoors should wear protective clothing, masks and goggles, and ordinary citizens should try not to go to densely populated places and wear masks when going out. This mode of transmission does not mean that the virus is in the air, do not cup the bow snake shadow.
However, people in life should still know Ormicus correctly. According to the investigation report of Beijing Disease Control, the vertical transmission of the high-density building is easy to occur through a variety of channels, and the air inside the high-rise building rises or falls along the space with a vertical slope, resulting in the phenomenon of air strengthening, in this process, when the wastewater from the toilet and washbasin is discharged, it will produce aerosols in the sewage pipe, which will produce the spread of the virus.
Therefore, the infection of the new crown virus caused by digging wild vegetables is traceable, and it is not a fake news that attracts people's attention. But many people will also be afraid of the air, thinking that the air is full of viruses, and That Omikeron is not strong because of the spread of aerosols, but that he himself is the result of generations of mutations. When the human body is injected with the new crown vaccine, it will produce certain antibodies to fight the virus.
In this round of the epidemic dominated by Omikerong, there have been "super-spreaders" in some parts of the country, and the number of viruses carried by them is high and the risk of transmission is large, which has not been seen before. Compared with the previous virus strain, it is more likely that a "super spreader" will appear in this infected person, which is similar to the "mother book" in the game, which can spread more than two dozen people by one person.
Third, how to be vigilant against Aumicron and prevent new crown pneumonia
When the previous virus strain Delta concentrated on the outbreak, its spread speed and intensity were not as strong as Omilton. According to studies, the virus before TheOmex is simpler to prevent than it is, for example, wearing a general medical and health mask can effectively prevent the spread of Delta virus. However, doctors remind that in the face of Aumicron, ordinary people need to wear N95 masks to strengthen prevention.
1. Strengthen the awareness of self-protection
In the case that the current epidemic situation has not been completely eliminated, the majority of residents must establish a firm sense of self-protection, which is more important than going out to get together and minimizing going to public places. Because Omi Kerong itself has a very high transmission intensity, and the transmission route of aerosols is more vigilant, so living at home, non-essential not going out should be the consciousness that everyone has in their hearts, which is also responsible for life.
In real life, people must go out, must always maintain a firm sense of self-protection, for example, in the case of The Ningbo case, it is because of negligence, did not wear a mask, thinking that they are in a well-ventilated place so there is no need for protection, which shows that most people still have a fluke mentality towards Omicron, but the virus is invisible and untouchable, do not lose your health because of negligence.
2. Do a good job of self-protection and strictly prevent viruses
Studies have shown that because the spreading ability of Aomi Kerong has been greatly enhanced, the possibility of super-spreaders has also increased, so it is necessary to do a good job of protection. In medium- and high-risk areas of the outbreak, the CDC recommends wearing N95 masks. At the same time, we should pay attention to hand sanitize at all times, do not touch the mouth and nasal cavity at the first time after touching other things, and at the same time, we should often prepare alcohol disinfection at home.
Because aerosol transmission may lead to mutual infection upstairs and downstairs, it is necessary to disinfect the hands and open the windows in time, because the transmission rate of TheOmilon indoors is 5-6 times that of the outdoors, so the more open the area, the lower the survival rate of the Omikeron and the lower the infection rate of the person.
3. Home sports
Why the proportion of people infected with new crown pneumonia and deaths in the elderly is quite high, studies have shown that it is because the elderly have low physical resistance and immunity, and they are more likely to be infected with new crown pneumonia and more likely to be crushed by pneumonia. Therefore, we must improve our immunity and resistance in order to better guard against new champions. When we are isolated at home, it is not to stay at home and not move, but to exercise moderately.
Home exercise can not only pass the boring time, but more importantly, it can enhance cardiovascular function, enhance resistance and immunity, and effectively reduce the risk of infection with the virus. Because of the epidemic control, many people are working from home, which is not good for the body, and you can properly jump rope, aerobics exercises, etc.
4. Vaccination of relevant vaccines
The research data of the Chinese Health Commission shows that the infection rate of the whole process of vaccination against the new crown vaccine is much lower than that of the unvaccinated population, and the population that has not produced effective antibodies to the new coronavirus pneumonia in the body belongs to the susceptible population, and they need to inject the vaccine of the new coronavirus pneumonia, so that the body can produce specific immunity against the new coronavirus pneumonia, and the whole process of vaccination is also an important preventive measure.
Many people think that vaccines are ineffective and cannot knock the virus down with one blow. In fact, even if a person who is vaccinated again is re-infected, his symptoms will be milder than those of patients who have not been vaccinated, and once a patient who has not been vaccinated is infected with the new crown virus, even if the later treatment is effective, there is a risk of leaving sequelae.
4. Summary
On this basis, people in life do not gather, do not get together, and strictly prevent mass cross-infection. Go in and out of public places to do a good job of sterilization and disinfection, so that the new crown virus has nowhere to hide. Personal health monitoring is also very important, if there is a suspicious situation, such as fever, cough, headache, muscle pain and other symptoms, do not take medicine without authorization, should measure body temperature in time, take the initiative to seek medical treatment, and do a good job in related prevention and control.
At the same time, less outdoor activities, reduce contact with others, usually open more windows for ventilation at home, especially relatively closed, poor ventilation rooms, pay attention to regular window ventilation, generally maintain ventilation for half an hour, so as to effectively prevent OmiceJong, many tragic cases are in front of you, do not covet a momentary pleasure, causing your own health to disregard.
