I'm doing a brochure on phneumonia for a school assignment. As you know, brochures are only supposed to have short, clear pieces of information.

One of my sub-headings for my brochure is "Are There Different Types of Pneumonia". I've done a lot of research on this and there are too many! So i'm trying to break it down.

My question is: Are there 2, maybe 3, common types of pneunomia so I can just talk about them? or
Can pneumonia be classified into Categories? or
Is there any other way I can shorten it?

Please try and list your sorce.

Thanks
