MANY DIFFERENT GERMS CAN CAUSE PNEUMONIA, including bacteria, viruses, and fungi. When we breathe in these germs, we can usually fight them off with our immune system and cough them out of our lungs. However, some people have a weakened immune system or can’t cough out the germs very well, and they end up getting an infection.
The main causes of pneumonia:
- Exposure to a germ (bacteria, virus, fungus)
- Weakened immune system
- Not able to cough out the germs/mucus from your lungs
Pneumonia is occasionally caused by inhaling chemicals (fumes, liquids, particles) in the workplace.
Unintentionally aspirating (inhaling) food or vomit into your lungs can cause “aspiration pneumonia”.
