How does the novel coronavirus pneumonia spread?

There are two main aspects:

First, transmission through the respiratory tract. Respiratory transmission refers to the formation of droplets or even aerosols by sneezing or coughing in patients infected with the novel coronavirus, after exposure to contamination, aerosols or droplets in the air of susceptible patients. Infection is the most important route of infection.

Second, contact transmission. It refers to contact transmission that occurs when an infected person comes into contact with a contaminated environment, and after an infected person is discharged into a polluted environment, such as touching it with his hands, the infected person sneezes on an object, and performs his or her own hand hygiene again.

For example, contaminated hands without good hand hygiene, touching mucous membranes, such as the eyes or eating food, are medically called fecal-oral transmission.

As far as is known, it is mainly through respiratory transmission and contact transmission.

At present, the main transmission routes that have been identified include: 1. Respiratory droplet transmission, which is caused by the direct inhalation of droplets by the infected person by sneezing, coughing, talking and exhaling the air in a short distance. Droplets mix in the air to form aerosols, which can also cause infection if inhaled.

2. Contact and contaminate susceptible fingers, and then contact the mucous membranes of the mouth, nose, eyes and other body parts, resulting in infection.

Opinions and suggestions: The transmission routes include droplet transmission, contact transmission, aerosol transmission, etc., it is recommended to wear a mask when going out, minimize going out, isolate at home, wash hands frequently, and disinfect with alcohol.

The main findings are mainly due to respiratory transmission, as well as contact transmission. In addition, it is not excluded that the infection of the digestive system, mainly the patient's sneezing, runny nose, cough book, droplets when speaking, and exhaled gas, close contact with healthy people, so that they can be directly inhaled and infected.

In addition, the patient's droplets mix with the air to form aerosols, which are finally inhaled by healthy people and lead to infection. In addition, droplets are deposited on the surface of objects, and after being contaminated by healthy people's hands, they can also cause infection in contact with mucous membranes such as the mouth, nose, and even eyes of healthy people.

1. Droplet transmissionDroplet transmission is when an infected person speaks or sneezes with the virusAnd you are unfortunate enough to be by his side, and thus you are infected with the virus. This should be the most common way to get infected, as you also can't be sure if the people around you are carrying the virus. And the spread distance of the virus is also relatively long, like ordinary talking droplets will spread about one meter, and if you sneeze will spread 2 to 3 meters.

2. Contact transmissionContact transmission is when a hand or other part touches an object that carries the virusAnd if you eat with your hands or rub your eyes, nose and other parts, it is easy for the virus to enter the body. Because the virus can survive for a few days on some items, this way of transmission is also relatively easy for people to catch.

So in general, the prevention method is still our common way to wear a mask when going out, wash hands frequently, etc. Other transmissions have not yet been confirmed definitively, and the conditions for transmission are not as common as these two, so as long as you take personal protection, you can defend against the virus.

The new crown pneumonia will be transmitted through droplets, feces, and it is said that it will also spread by hot melt adhesive, and the best way to prevent it is not to go out, and if you go out, you must wear a mask and wash your hands frequently.

Through airborne transmission, if you communicate with someone who is sick and do not wear a mask, you are likely to be infected, and I feel that I must not go out at home, and I must wear a mask when I go out.

Mode of transmission: infected feces, sneezing, saliva, close contact, etc.;

The best way for us to deal with this is not to go out and wait for the epidemic to end; In addition, you should also pay attention to hygiene and wear a mask when you go out.

The virus can be inactivated with 75% alcohol, ether, chloroform, formaldehyde, chlorine-containing disinfectants, peracetic acid and ultraviolet light for the transmission of viral pneumonia caused by the novel coronavirus.

The virus is sensitive to heat, 56 °C, 30 minutes, 75% alcohol, chlorine-containing disinfectant, hydrogen peroxide disinfectant, chloroform and other lipid solvents can effectively inactivate the virus, the virus can not exist and reproduce independently, without the living organism, it can not survive for a long time, let alone reproduce.

Common signs of coronavirus infection include respiratory symptoms, fever, cough, shortness of breath, and difficulty breathing. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure, and even death. At present, there is no specific ** method for the disease caused by the novel coronavirus.

However, many symptoms are manageable and need to be treated clinically**.

Novel Coronavirus Prevention:1. At homeAs a contagious disease, SARS has its source of infection, transmission routes and susceptible populations. For the first two, it is especially important to wash your hands frequently.

Wash your hands before eating, before touching your mouth, eyes, nose, etc., cover your sneezes and coughs with a handkerchief or tissue, clean your hands, and wipe them dry with disposable tissues after washing your hands.

2. OutdoorIn addition, the number of visits to public places should be minimized during the severe period of the epidemic; It is best to sit in a ventilated place when taking the bus, and if the vehicle is crowded, try to change to other vehicles; When taking a taxi, pay attention to whether the disinfection date is updated on the same day.

Wash your hands with soap and water or disinfectant after meals, wash your hands after going to the toilet, don't go to crowded places, and do a good job of prevention and control.

What kind of disinfection method is the new coronavirus most afraid of, and how to disinfect the home.

Do not gather, wear a mask, ventilate the room frequently, wash hands carefully, eat lightly, drink enough water, ensure sleep, and maintain normal immunity. If you do this, you will be able to prevent viruses to the greatest extent.

Novel coronavirus pneumonia refers to pneumonia caused by infection with the new coronavirus. Since December 2019, some hospitals in Wuhan, Hubei Province, have successively found a number of cases of pneumonia of unknown cause with a history of exposure to the Huanan seafood market, which has now been confirmed to be an acute respiratory infection caused by novel coronavirus infection.

The etiological characteristics of coronavirus introduce the subfamily Coronaviruses into four genera, , and δ. Together with the newly discovered coronavirus, there are 7 types of coronaviruses that are known to infect humans. Most coronaviruses cause upper respiratory tract infections, but MERS-associated coronaviruses, SARS-associated coronaviruses, and this novel coronavirus can cause pneumonia and even severe pneumonia, and can spread from person to person.

Coronaviruses are sensitive to ultraviolet light and heat, and most disinfectants can effectively inactivate the virus, but chlorhexidine cannot effectively inactivate the virus, so hand sanitizers containing chlorhexidine should be avoided.

In this case, try not to go to crowded places to join in the fun, wear a mask when you go out, and choose a surgical mask or N95 mask is effective, a medical surgical mask can block 70% of bacteria, and N95 can block 95% of bacteria.

1. Wash your hands frequently: Use soap and water to wash your hands, or hand sanitizer containing alcohol.

2. Use a tissue or bend your elbow to cover your mouth and nose when coughing and sneezing;

3. Avoid close contact with anyone with cold or flu symptoms;

4. The home should be ventilated frequently;

5. Avoid contact with livestock, poultry and wild animals when there is no protection.

Prompt medical attention is required if you have any of the following symptoms:

cough, sputum production;

fever (temperature > 38);

Difficulty breathing during daily activities or at rest;

pain when taking deep breaths;

rapid heartbeat; Sudden deterioration of the condition after a cold or flu has improved;

Chill. If you feel unwell, try to stay at home and don't go out. If you have any of the above symptoms, please wear a mask and go to the hospital in time.

Learned! Be sure to wash your hands frequently, keep indoor air circulation, don't go to crowded places, and wear a mask when you go out.

On August 19th,The National Health Commission said the new coronavirus was more contagious within five days of the onset of the disease. In addition to this time, it is also contagious。A new version of the diagnosis and treatment protocol has also been released.

Since its emergence, the novel coronavirus has caused a wide spread. Although the fatality rate is not as high as SARS, it should also attract enough attention, after being infected with the new coronavirus, the incubation period is generally one to fourteen days, but the incidence rate is relatively high in three to seven days. <>

The new coronavirus is also contagious during the incubation period, and asymptomatic people infected with the new coronavirus can also transmit the virus, and the population is generally susceptible to infection. The novel coronavirus is mainly transmitted through respiratory droplets and close contact. The virus has also been found in the feces and urine of infected people, so it is necessary to be aware of its pollution to the environment and the spread of the virus.

Prevention and isolation need to be strengthened. It is more contagious within five days of the onset of the disease, so it is necessary to pay more attention. But in addition to this time, the virus can also be contagious, and we need to take strict precautions.

When we go out, we should pay attention to wearing masks, avoid crowded places, and do a good job of self-protection to stay away from the new coronavirus. <>

After being infected with the new coronavirus virus, people will have different symptoms after the incubation period. Among them, it can be divided into severe patients, critical patients, and mild patients. The first two have a low-to-moderate fever or even no significant fever.

Mild cases may present with symptoms such as low-grade fever and mild fatigue. Typical symptoms are fever, weakness, and dry cough. Some patients may have nasal congestion, runny nose, sore throat, and diarrhea.

Severe patients will be blind to symptoms of dyspnea and hypoxemia one week after the onset of the disease, and in severe cases, organ failure may occur.

Currently, there are two different ways to test for the coronavirus. The first can be collected by detecting secretions from a person's throat, nose, respiratory tract, feces and urine. The nucleic acid of the new coronavirus pathogen can be further determined by measuring whether the sample is infected by the new coronavirus.

The second is to do a blood test, where the patient is tested to see if he or she is infected with the new coronavirus.

First of all, you should plan your travel route and transportation mode in advance before you travel. Know the fares, schedules and schedules of various modes of transportation, as well as the routes and timetables of various modes of transportation, so that you can avoid delays and omissions caused by not having time to inquire on the day of travel. At the same time, you can choose some sub-peak hours, such as outside the peak working hours, or at the time of alternating morning and dusk.

These times are not crowded and congestion can be avoided and traffic jams in rush hour areas can be avoided.

Second, there is the option of using the highway or the fast lane. These roads are faster than those in urban areas and have relatively low traffic flows. So, if the place you are going to can be reached by highways or fast lanes, then try to choose these routes.

Again, learn to manage your time wisely. It is best to go out early to allow enough time for unexpected situations that may arise on the way, such as traffic accidents, weather effects, etc. Also, try to stagger peak travel, such as morning or afternoon departures, or late night or early morning departures.

In this way, you can avoid competing with others for road resources and reduce traffic congestion caused by excessive traffic.

Finally, precautions should be taken before traveling. By wearing masks, carrying tools such as disinfectant, and maintaining hand hygiene in a timely manner, Yuanwei can reduce the spread of the epidemic. At the same time, it is necessary to pay attention to obey traffic rules, travel in a civilized manner, do not speed and overload, do not change lanes at will, and maintain safety measures such as vehicle distance.
