Some people say that more than 90% of people today have been infected with the new coronavirus and then recovered. What I want to say is that the first half of the sentence is correct, but the second half is incorrect.
Most people have a fever, but a small number of people have mild symptoms. Coughing is normal. If you keep coughing, you should avoid tuberculosis .

People who often cough will develop respiratory diseases. This is something that no one expected. So, don’t believe what others say. If you are infected with the new coronavirus, you will have antigen after you recover.
You must believe that after being infected with the new coronavirus, the second infection will not necessarily be the new coronavirus that was infected last time. 
virus is a highly variable bacterium . It is a bacterium that takes away toxins. In short, it is a toxin that attacks the immune system .
If you understand it this way, everyone can understand that there is only one way to avoid secondary infection, which is to protect yourself.

Many people have been queuing up, but have no way to see a doctor. This kind of thing is happening, happening around us. Friends, do you have it around you?
I want to buy medicine, but I can't. I want to go to the hospital, but I can't get in. I want to register, but the queue is several days away. This is the reality.
