Question

what are the causes of pneumonia
​

Answer 1

Answer:

Infection that inflames air sacs in one or both lungs, which may fill with fluid.

With pneumonia, the air sacs may fill with fluid or pus. The infection can be life-threatening to anyone, but particularly to infants, children and people over 65.

Answer 2

Answer:

Viruses, bacteria, and fungi can all cause pneumonia.A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus). However, clinicians are not always able to find out which germ caused someone to get sick with pneumonia.

Explanation:

Community-acquired pneumonia is when someone develops pneumonia in the community (not in a hospital). Healthcare-associated pneumonia is when someone develops pneumonia during or following a stay in a healthcare facility. Healthcare facilities include hospitals, long-term care facilities, and dialysis centers. Ventilator-associated pneumonia is when someone gets pneumonia after being on a ventilator, a machine that supports breathing. The bacteria and viruses that most commonly cause pneumonia in the community are different from those in healthcare settings.
