I have been coughing for 8 days. First of all, I rule out virus infection. I think it may be a bacterial infection.

Secondly, it can be determined that the focus is upper respiratory tract infection.

Symptoms such as fever, body aches, cough, etc. It is caused by bacterial infection of upper respiratory tract. It is confirmed as an upper respiratory tract infection, and such symptoms are generally not cited as a reference.

In addition, cough, as a symptom, is of no reference value if the doctor does not judge that there is no inflammation in the exhalation.

Symptom explanation:

1 Upper respiratory tract infection causes a series of symptoms such as fever and cough.

Cough is caused by bacterial infection expanding and moving to the throat. Because the throat is inflamed, the defense mechanism is activated. The sputum increased and attached to the bacteria near the throat, which led to the nerve reflex behavior-cough. Cough is to cough up phlegm with bacteria attached to it. Therefore, cough is called the range of bacterial infection.

Fever is caused by bacterial infection, and the defense mechanism is activated to produce phagocytes (white blood cells/lymphocytes), because phagocytes will increase rapidly and devour pathogenic bacteria, and the increase of phagocytes will increase oxygen consumption, thus reaching the condition of fever.

Conclusion:

First of all, the focus of drugs-antibiotics

Second, protective antitussive.

PS: Look at the medicine the doctor prescribed for you.

Compound codeine phosphate oral liquid takes effect quickly, mainly to relieve cough, but has no anti-inflammatory effect. But if the cough is not very severe, I suggest taking compound hay mixture, which will protect the subcutaneous layer and prevent the throat from being damaged by excessive cough.

Azithromycin is the main drug to treat lesions. If you go to see a doctor, you might as well ask the doctor to prescribe levofloxacin lactate for you. This medicine takes effect quickly, quickly.

If the trachea is fine and the lungs are fine, don't worry. Take care of yourself!

Cough for 8 days. Does this rule out virus infection first?

I don't think this rejection makes sense.

The duration of virus infection will last for several months or even years, not excluding 8 days.

On the contrary, I think it's a virus infection, so we should take antiviral drugs quickly.

Explanation:

The duration of a general virus attack is 7 days. The virus will die naturally in more than 7 days.

The attack here is not an incubation period. The onset of the disease occurs after the incubation period.

Generally speaking, virus infection can only be diagnosed by laboratory examination.

PS: Now when I go to some medical schools affiliated to universities, some doctors will suggest doing some tests to help patients diagnose. Some people think it's a waste of money or doctors help hospitals cheat patients. However, I can tell you responsibly here that doctors can't accurately judge whether it is a virus infection. There is almost no difference between viral infection and bacterial infection in the body. The simplest ones are flu and cold. Why do you say staying up late is easy to catch a cold? Because the immune mechanism is low, bacteria attached to the respiratory tract take the opportunity to invade and cause colds. There is a big difference between flu and cold. Influenza is a virus that infects the respiratory tract through droplets and some indirect contact with normal immune mechanism. Do you think these differences are obvious in physical performance?

Now go to some small hospitals, and doctors usually prescribe two kinds of drugs. One is antibiotics and the other is antiviral drugs. Of course, this is the prescription given by the doctor when you told him that I had a cold these days. Those hospitals either can't do similar tests or are bored. Because taking antiviral drugs and antibiotics in a short time is not very harmful to the body. If the medicine is used properly, the symptoms will be relieved or disappeared in a short time.

You seem to understand when I say this. To some extent, doctors in some hospitals prescribe drugs indiscriminately now.

Finally, I want to tell aadbdadas not to use antiviral drugs and antibiotics indiscriminately. If in doubt, you should seek medical advice as soon as possible.
