A. Public health looks at everyone from all over. We (I’m an epidemiologist) are concerned with things that may be coming down the pike and hit all of us (like bird flu, etc.). Community health mostly involves doctors, nurses, and other health care professionals that tailor interventions to a particular community’s needs, and they generally don’t plan out for the bigger picture, although they do a heck a job in their locales, since they know it better.
