Will I ever get pneumonia before?

If you have had pneumonia before, you may not be infected again if you have strong autoimmunity and take precautions. However, if the patient is in poor physical condition and does not take protective measures, etc., he may be re-infected.

One, it won't

1. Strong autoimmunity: If you have been actively treated with pneumonia before and are vaccinated in time after being cured, your own immune system can play a certain role in defense, and you can also do a good job of protection in daily life, such as wearing a mask when you go out, washing your hands frequently, etc., usually you will not get pneumonia again;

2. Failure to take protective measures: Although you have suffered from pneumonia in the past, if you do not do a good job of personal care and protection, such as frequent access to crowded places or sharing daily necessities with infected people, it may lead to pathogens re-invading the mucosal tissues of the lungs and inducing pneumonia.

Second, it will be obtained

For people with poor physical fitness, especially the elderly or infants and young children, it is easy to reduce resistance due to age, and the physical functions of such people will gradually deteriorate, so they are more susceptible to the invasion of external pathogenic bacteria, thereby increasing the probability of disease. In addition, if you do not isolate or share personal belongings with others during the onset of the disease, cross-infection may also occur, which can also cause a recurrence of pneumonia.

It is recommended to develop good living habits, avoid going to crowded places, and wear a mask when going out to minimize the probability of disease.
