Do you hate New crown ?
For most people, they are not afraid of the new crown in their hearts, but they hate the new crown very much!
What changes will happen if you unfortunately get infected with the new coronavirus?
Imaging changes: Early in the early stage, small frosted glass-like nodules, small patches and interstitial changes were frequently encountered in both lungs, and the entire lung lobe was blurred, which was more common in the take-up of both lungs.
As the disease progresses, large areas of ground glass shadows and patchy shadows can appear infiltrate. The infiltration gradually increases and connects to each other into pieces. In severe cases, it develops into a solid shadow. The entire lung lobe will be solidified or partially solidified, and it may be in both lungs.
When severe, the entire lung will undergo a solid change, commonly known as the big white lung;
pleural effusion : pleural effusion is mainly reactive pleural inflammation caused by pleural inflammation , also known as parapneumonia effusion, and systemic inflammation. The reaction is related to inflammation in the pleura and lungs;
clinical changes: fatigue, fever, cough, chest tightness, , asthma and difficulty breathing. Coughing is mainly dry cough, no sputum or a small amount of sputum, which cannot be vomited. When bacterial infection is combined in the later stage, phlegm of the corresponding color will appear according to the characteristics of the bacterial infection.

Why is the new coronavirus so difficult to eradicate?
——Highly contagious, mild symptoms
The biggest difference between the novel coronavirus and SARS in 2003 is that it is mild but contagious.
Before the outbreak of the epidemic in Wuhan, people had some understanding of these two diseases, but with the continuous spread of the new coronavirus, this situation became more and more serious. Experts remind the public to be alert to flu or respiratory infection caused by the novel coronavirus infection.
associate professor of pathogenic biology at Wuhan University School of Basic Medicine said that SARS is more contagious after symptoms such as fever and pneumonia are present.
This time the incubation period of the novel coronavirus is about 12 days or more, and it is not acute and some patients are asymptomatic.
—It is difficult to eliminate
Comparison of "smallpox" and " polio ", and experts found it difficult to eradicate the new coronary pneumonia.
It is not clear how long the immune protection against COVID-19 infection can last. Some patients have secondary infections, which indicates that this immunity may be limited.
—It is difficult to coexist in the short term
According to the nature of the virus, vaccination needs to be popularized, and then special drugs are provided to achieve coexistence between humans and viruses, while waiting for the virus to naturally evolve into a strain with less toxicity.
In addition, the mortality rate of COVID-19 is nearly 7 times that of influenza, and there are no seasonal restrictions, which makes it unable to coexist with the virus for a long time.
——Vaccine coverage is low
There is no high vaccination coverage rate, and it is almost impossible to eliminate the new coronavirus pneumonia.
However, data shows that there seems to be no sign of control of the new coronavirus worldwide, and China is the only country to successfully control the epidemic so far.
