Internal Medicine encompasses the care of all adults, healthy and sick. Internists (as all doctors who complete an internal medicine residency are called) can be generalists or subspecialists, like cardiologists or rheumatologists. If you choose not to subspecialize, you are known as a General Internist.
Most infectious diseases can be diagnosed and treated by a general internist. In cases where diagnoses is difficult, prescribed treatment has failed, or when a fever presents itself alongside an infection, a general internist may refer a patient to an infectious disease specialist.n infectious disease specialist may perform a bacterial culture so as to identify a specific disease. Some specialists have access to IV antibiotic therapy that allows antibiotics to be injected directly into a patient's veins. An infectious disease specialist may treat infectious diseases of the heart.
