In brief: Sometimes

Some bacterial infections are, like strep throat, or pink eye, but many develop that are not really contagious, like sinusitis, cellulitis, or diverticulitis.
If you have a concern, you should discuss the specifics with your doctor. It is also always a good idea to always wash your hands or use hand sanitizer, whenever you are out, like shopping, airports, grocery stores etc to minimize risks.
