Question

Can pneumonia have a permanent affect on lung function?

Answer 1

Pneumonia is of two types.

BRONCHOPNEUMONIA

LOBARPNEUMONIA

Difference is that in lobar pneumonia(caused by Streptococcus pneumoniae,Klebsiella pneumoniae,Haemophilus influenzae etc.)the virulence of the pathogenic organism is low,so that damages caused by it are only limited to a lobe and they don't affect the basic structures of lung and also recovery is the rule.

But in Bronchopneumonia(caused by Staphylococcus aureus,Yersinia pestis etc.) the virulence of the organism is very high and it destroys the basic architecture of lung parenchyma and also invade through the fissures to affect the whole of lung.Ultimaltely result in permanent damage to the lungs with severe fibrosis.
