Washing Hands “Infectious diseases are caused by microscopic organisms that penetrate the body’s natural barriers and multiply to create symptoms that can range from mild to deadly,” according to the Infectious Diseases Society of America.

Many common infections can be treated by a primary care doctor.

However, your doctor might refer you to an infectious disease specialist when an infection is difficult to diagnose, an infection is accompanied by a high fever, or a healthy person plans to travel to a location or foreign country where infection risks are higher.

In all of these cases, the specialized training and diagnostic tools of an infectious disease specialist can help determine the cause of an infection and the best treatment options.
