How long does it take for pneumonia to become contagious

There is no clinically clear time for the onset of symptoms of pneumonia infection. Typically, clinical symptoms may appear within 1-2 days after pneumonia, or it may take 7-10 days for symptoms to appear.

1. Acute phase

1.1-2 days: If the patient is in good physical condition and belongs to the group without underlying diseases, after being infected with the pneumonia virus, the body's immune system can remove the pathogen, so it will not cause obvious uncomfortable symptoms;

2.7-10 days: For some patients with poor constitution or underlying diseases, such as the elderly, children and other people, as well as patients with chronic diseases such as diabetes and hypertension, the patient's immunity will be reduced at this time, and when infected by the pneumonia virus, it may cause the disease to develop rapidly, and symptoms will generally appear 7-10 days after infection.

2. Recovery period

If the patient is diagnosed with pneumonia, it is recommended to follow the doctor's instructions for treatment in time to avoid delaying the condition. For patients with mild pneumonia, drugs such as amoxicillin capsules and cefixime tablets can be used under the guidance of doctors to control inflammatory reactions and relieve symptoms such as cough and sputum production. For patients with severe pneumonia, respiratory function should be improved by oxygen inhalation, and endotracheal intubation and other methods should be used if necessary.

In daily life, we should also pay attention to maintaining indoor air circulation, avoid going to crowded places, and wear masks when going out to reduce the occurrence of cross-infection.
