The old saying goes: "The epidemic is only three." Now the new coronavirus has been facing nearly three years and is still raging around the world.

Although my country has made great progress in the prevention and control of the new crown epidemic, and has also vaccinated people with the new crown vaccine for free, it has not completely disappeared.

At this time, many people will ask questions, what will the world be like if the new crown epidemic does not end? Let’s take a look together below.

[ How harmful is the new coronavirus ]

New coronavirus generally refers to novel coronavirus pneumonia . The new coronavirus pneumonia has a greater degree of harm, which can easily cause epidemic outbreaks, physical damage, and may also endanger life and leave sequelae.

. Epidemic outbreak: The cause of novel coronavirus pneumonia is novel coronavirus infection, and the novel coronavirus is highly contagious and can be transmitted through direct contact, indirect contact, etc. It can also be transmitted through respiratory droplets and aerosol , so it is easy to cause large-scale transmission, resulting in epidemic outbreaks;

. Physical damage: After suffering from novel coronavirus pneumonia, patients will experience many adverse symptoms such as fever, cough, decreased sense of smell and taste, and sore throat. If not treated in time, the condition may develop into severe or critical condition, and may also cause adverse conditions such as acute respiratory distress syndrome, coagulation dysfunction and organ failure, which may cause serious damage to the body;

. Life-threatening: When the novel coronavirus pneumonia is not controlled in time, it may even affect central nervous system , and It may lead to ischemic necrosis of the limbs. In severe cases, it may even endanger life due to multi-organ failure;

. Residual sequelae: If the novel coronavirus pneumonia develops into severe or critical condition, sequelae may occur after the condition is cured, such as cognitive impairment , mental impairment and physical dysfunction, which will affect normal life.

[How many ways of spreading the novel coronavirus? 】

Novel coronavirus pneumonia is referred to as new coronavirus pneumonia. It refers to pneumonia caused by the new coronavirus infection. It is currently the world's largest public health incident . The main transmission routes of COVID-19 are as follows:

. Respiratory droplet transmission: refers to infection caused by the patient's mouth and nose when he sneezes, coughs or speaks, and is inhaled into the airway by other healthy people who are close to it;

. Close contact transmission: refers to infection caused by droplets deposited on the surface of the object, and after the hands contact pollutants, and then contacting the mucosa such as the mouth, nose, eyes, etc. Contact with items contaminated by viruses may also cause infection.

In a relatively closed environment and long-term exposure to high concentration aerosols, there is also the possibility that aerosols will spread . The new coronavirus can also be isolated from feces and urine, so you should pay attention to its contact transmission and aerosol transmission caused by environmental pollution.

[Early symptoms of new coronavirus infection]

. Fever: is the main symptom of new coronavirus patients, but a small number of patients have no fever symptoms. Due to the new coronavirus, the lung inflammation is caused, resulting in a large number of inflammatory factors and cytokine , which stimulates the body temperature center and produces fever;

. Fatigue: It is mostly caused by systemic inflammation reactions.

. Breathing: that is, chest tightness . Due to obvious inflammation of the lungs, the alveolar function is reduced, resulting in dyspnea and chest tightness and shortness of breath;

. Dry cough: Viral infection causes inflammatory stimulation of lung tissue and causes cough, and dry cough varies from person to person;

. Diarrhea: Because the virus produces excessive toxins in the body, gastrointestinal dysfunction , resulting in diarrhea. In addition, the virus is prone to acid-base imbalance in the body, leading to metastatic acidosis;

. Chest pain: When a new crown patient coughs violently, it will induce chest pain, which may be accompanied by pathological changes in the chest;

. Headache: Because new crown patients will have symptoms of fever, it can easily cause brain blood vessels to dilate, stimulate peripheral nerve , causing headache;

. Dizziness: Because new crown patients have symptoms of fever, difficulty breathing, and shortness of breath, it is easy to cause temporary brain hypoxia, thereby guiding It causes dizziness, but it should be noted that not all patients with dizziness are caused by COVID-19;

, conjunctivitis : It is mainly because the virus can cause infection by contacting the conjunctiva of the eye. Patients often show dry eyes, itchy eyes, tears, etc.;

0. Nausea: New coronavirus infection can easily lead to gastrointestinal dysfunction, and a few patients may experience nausea and vomiting;

1. Disorders in smell and taste: Some patients will experience olfactory and taste disorders, which are newer symptoms of new coronavirus infection.

[What will the world be like if the new crown epidemic has not ended? Medical experts tell the truth】

Director-General of Social Organization Tedros Adhanom Adhanom 2 warned that the COVID-19 pandemic is far from over, and in the foreseeable future, human beings will always coexist with the COVID-19 virus.

But coexistence does not mean letting the virus raged, because the world cannot "bet on a virus that we cannot control or predict its evolutionary trajectory".

People have different ideas about how the new crown pneumonia epidemic will develop and how the most serious stage will end, but it is dangerous to assume that the mystery Kerong will become the last mutant strain or the new crown pneumonia epidemic is about to end.

On a global scale, more mutations are likely to occur under the current situation. In order to change the development process of the epidemic, we must change the conditions that drive it, and this is not an easy thing, and there is no ready-made method.

At present, the Chinese government has listed the new coronavirus as the main isolation and protection virus. China's infectious diseases has included the new coronavirus pneumonia in Class B infectious disease , but it adopts the management method of Class A infectious diseases.

From Epidemiological , it becomes an endemic disease when a certain disease is stable in a specific region or at least predictable, and becomes a common disease just like a seasonal cold.

However, the new coronavirus is very contagious and there are many ways of transmission, which is one of the main reasons why the new coronavirus occurs repeatedly.

Academician Zhong Nanshan has made very important contributions to the research on the new coronavirus, and Academician Zhong Nanshan has also made the latest response. At present, from the analysis of the epidemic transmission in various places, it is true that the new coronavirus is very transmissible, but the toxicity seems to be getting weaker and weaker.

The occultness and transmission of the new coronavirus are obviously increasing, otherwise this wave of epidemic should not be so serious.We now see that the epidemic in many places in Guangzhou and Chongqing is very severe, with strong transmission, but the toxicity is getting weaker and weaker.

More experts have begun to say that the current epidemic is the reduction in the current virus toxicity is a trend. We ordinary people do not understand the reason. The new coronavirus is the self-limiting disease , so there is no need to be too scary. From the data analysis in various places, it can be clearly seen that it basically has no severe and critical cases. This also confirms a situation where this toxicity is getting weaker.

The awareness of prevention of the future of the new coronavirus cannot be relaxed. Although some places have gradually opened up and have begun to voluntarily conduct nucleic acid testing for , everyone should not relax their vigilance.

To sum up, the new coronavirus is also a new virion. When a way to completely eliminate it has not been found, it may exist for a long time.

At present, the understanding of the new coronavirus is not clear enough, but the coexistence with the virus will also increase our immunity , so there is no need to worry too much. As long as preventive measures are used to isolate the source of infection and the transmission route, it can effectively prevent large-scale spread.

[Faced with the new coronavirus, we must still be vigilant! 】

1. Stay away from the source of infection: Do not go to the epidemic area, avoid patients or suspected of contact with new coronavirus pneumonia, do not go to places with dense crowds, and cancel activities with a gathering nature. When outside, you should consciously keep a distance of more than one meter from others. If you cough or sneeze, use a tissue or bend your elbow to cover your mouth and nose, and reduce dine-in outside;

2. Self-protection: Do a good job of personal self-protection, wear medical or protective masks correctly when going out, and do not touch your eyes, nose, mouth and other positions with both hands to prevent the increase of the chance of infection. Try not to touch external items when going out. After returning home, spray and disinfect your hands and whole body with 75% alcohol, and effectively clean your hands;

3. Healthy diet: According to the National Health Commission's research, the new coronavirus may be a virus caused by wild animals, so try to avoid contact and eating wild animals to prevent direct infection. Inges more foods containing high-quality protein, such as fish, eggs, milk, and fresh fruits and vegetables rich in vitamin C, such as kiwi , oranges, spinach, etc.;
