Welcome to e health forum.

Asthma is due to a hyper-reactive airway, which causes bronchoconstriction post exposure to various stimuli, and this results in symptoms like spasmodic cough and breathlessness.

Pneumonitis is due to inflammation associated with infections (Viral, bacterial, etc), and this is not due to hyperreactive airway.
