Moderate: May yet be viral- but probably aren't toxic looking enough to hospitalize if doc did not do that - take rest and avoid tobacco smoke or smog, also wash hands and finish antibiotics course once you start it to prevent resistant strains from surviving to do you in years later in life.

Difficult to say: Difficult to answer specifically, so you should talk with your doctor. In general the "seriousness" of pneumonia can be judged by several factors.The risk posed by pneumonia is increased with age > 65, a fast rep rate or low blood pressure, confusion or delirium, and certain abnormal blood tests indicating problems with kidney function. Coexisting serious illness also increases risk.
