Hi,

How should we differentiate between the following three words:

1. pneumonia
2. pneumonitis
3. pulmonitis

Thank you very much!

Are you sure we should?
"Pneumonia" is generally used for infectious lung diseases.
A chemical pneumonitis/pulmonitis (inflammation of the lungs) such as silicosis or asbestosis is not generally referred to as pneumonia unless there's an element of infection.

Thanks man! I just had no idea what was the difference before you told me, 'cause the dictionary says that they are the same meaning. Besides, practically I don't think we should differentiate from them,either.
