How will i know what does an infectious disease specialist do?

Treats infections: An id specialist treats all infections caused by micro-organisms including viruses, bacteria, fungi, protozoa and parasites. We treat infections of every organ of the body. Examples include pneumonia, pyelonephritis(kidney infection), osteomyelitis(bone infections), hiv/aids, meningitis, amoebic dysentery etc. Etc. Some id docs mainly do hospital consultations while some have office practices.
