Is pneumonia contagious?

The bacterial infection of adult pneumonia is Streptococcus pneumoniae. Other pathogens include anaerobic bacteria, Staphylococcus aureus, Haemophilus influenzae, Chlamydia pneumoniae, Chlamydia psittaci, Chlamydia trachomatis, and other Gram-negative bacilli. These pathogens may be transmitted through contact between people, or through contact between people and things, but even if infected with these pathogens, as long as the immune system is healthy, you will not get pneumonia. Often, when the body's resistance declines, the pathogen will take advantage of it and make people sick.

The transmission route of pneumonia:

1. Air inhalation:

A very infectious way for patients with pneumonia is airborne inhalation, which is also a reason why pneumonia is a common infectious disease.

2. Transfer of other parts:

For patients with other systemic diseases, such as patients with intestinal tuberculosis and other diseases, pay attention to the transfer of Mycobacterium tuberculosis, because Mycobacterium tuberculosis is easy to breed in any part, that is, tuberculosis can occur in any part of the body, so it must be caused Value.

3. Blood circulation in other parts of the body:

In infectious pneumonia, pathogens such as bacteria are easily exposed to the risk of spreading the whole body with the blood, of course, including the lungs, so after the inflammation is found, it must be controlled in time. Usually pay attention to the hygiene of local wounds.

4. Aspiration of colonization bacteria in upper respiratory tract:

For patients with upper respiratory tract infections, especially chronic patients, they are likely to have colonizing bacteria, so as time goes on, they may be inhaled into the lungs, causing pneumonia.
