Starting from the New Year of 2020, the whole country has been shrouded in the haze of the COVID-19 epidemic. It has lasted for two and a half years. Not only China, the COVID-19 epidemic has also become an international disaster.
At present, the new coronavirus is like a time bomb, making people uneasy, fearing that they will be infected by accident. Many people have asked why the epidemic lasts longer than imagined? When will the new coronavirus epidemic end?
So far, there have been many large-scale plagues in human history, but they often disappear in less than three years. Now that the new crown epidemic has lasted for nearly three years, will there be any changes in the second half of this year? How about getting better?
Do you really understand new crown ?
. The source of the new coronavirus
The new coronavirus may come from bats, because bats may be the host of the new coronavirus, and some people may be infected if they have close contact with bats or eat bats. To prevent COVID-19 infection, you must take personal protection, avoid contact with wild animals, and avoid eating wild animals.
. The transmission route of the new coronavirus
(1) Droplet transmission
The droplets generated by coughing, sneezing, talking, etc. enter the susceptible mucosal surface;
(2) Contact transmission
After touching something that an infected person has touched. Touching one's mouth, nose or eyes can spread the virus;
(3) Airborne
pathogens can remain contagious after being spread over long distances for a long time.
(4) Fecal-oral infection
is the rotavirus that exists in the patient's feces. After being excreted, it often contaminates water sources, food, clothing, toys, utensils, etc. When healthy people come into contact with these items, they will pass through their hands and mouth. It enters the human body and causes gastrointestinal diseases.
. Susceptible groups of the new coronavirus
(1) Elderly people
The elderly’s physical abilities gradually deteriorate, and their immune and organ functions are weaker than those of young people, making them susceptible to infection. Older people are at higher risk of contracting COVID-19.
(2) Patients with basic diseases
Authoritative research reports that among many patients with severe COVID-19, most suffer from respiratory diseases, diabetes, hypertension, , etc. Patients with serious underlying diseases are infected with COVID-19 and should be more careful not to get infected.
(3) People with low autoimmunity
usually have excessive mental stress, insufficient normal exercise, and uncoordinated spleen and stomach. Most of the patients have phlegm, dampness and qi deficiency and are prone to damage lung qi. After lung qi is insufficient , it is easy to be affected by external environmental factors and easy to feel.
. Symptoms of infection with the new coronavirus
After being infected with the new coronavirus, the main symptoms are: dry cough, fatigue, and fever. Some patients may be accompanied by chest tightness, shortness of breath, or even difficulty breathing. In severe cases, functional damage to multiple organs may occur, or even clinical death. A small number of patients may experience nasal congestion, sore throat, muscle aches and diarrhea.
It is recommended that for patients with a history of epidemiological , when the above symptoms appear, they should complete blood routine , chest CT, and new coronavirus nucleic acid testing as soon as possible to diagnose the presence of new pneumonia.
The COVID-19 epidemic has lasted for three years. Will it get better in the second half of the year? Academician Zhong Nanshan tells the truth
The successive epidemic cases in many places across the country have made people feel anxious. The arrival of the epidemic has not only delayed normal production, but also caused the loss of income sources for ordinary people. People have long been prepared for the end of the new coronavirus epidemic. I have longed for it.
The team of Academician Huang Jianping of Lanzhou University has published a journal and made a bold prediction for the end of the new crown pandemic:
By November 2023, the daily number of new crown cases worldwide will drop to about 3,000. In other words, it can be considered that the popularity of and is over at this time.
People couldn’t help but cheered after hearing the news, but is such a prediction really reliable?
Academician Zhong Nanshan said that the epidemic may exist for a long time, but large-scale spread can be controlled, and we will gradually open up during the dynamic eradication process, which shows that the epidemic can still be prevented and controlled.
During the ongoing epidemic, improving immunity is the only way
Professor Zhang Wenhong is the leader of the new coronavirus pneumonia senior expert group. He once said in a lecture:
There is no miracle drug in the world that can quickly eliminate the virus. During this epidemic, many patients had mild or asymptomatic infections and recovered even without particularly complicated treatment. Therefore, We can learn that human immunity is very important, and a large part of viral diseases are cleared through immunity.
Therefore, in addition to personal protection during the epidemic, we must also focus on improving personal immunity.
. A balanced diet
ensures a comprehensive and balanced nutritional intake to maintain the nutrients and trace elements required by the body. Because many trace elements are related to the non-specific immune function of the human body, once trace elements are lacking, immunity will decrease.
. Combining work and rest
The pace of life in modern society is accelerating. Many people work too hard and do not pay attention to rest, or young people are overly addicted to pleasure, which will damage their health. Pay attention to strengthening physical exercise. According to Chinese medicine, righteousness exists within the body and evil cannot be affected. With a strong body, immunity will naturally improve.
. Stay in a good mood
Research has found that happy people are more likely to have good immunity than depressed people. This is because a good mood can cause the brain to secrete some healthy chemicals, activate the body's immune function, and inhibit the growth of pathogenic microorganisms .
