Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi. The diseases can be spread, directly or indirectly, from one person to another. Some pathogens are spread through the air, surface contact or insect bites. Symptoms and treatments vary, depending on the nature of the infection.
Our approach to infectious diseases
Physicians in our infectious diseases teams are recognized authorities in the diagnosis and treatment of infectious illnesses in children and adults. Our team offers compassionate, professional care in our clinics and through our hospital partnerships. Faculty physicians treat patients with inherited or acquired immunodeficiency, including those receiving immunosuppressive therapies.
Some infectious diseases can be easily treated, but others require specialized diagnosis and treatment. Vaccines are an effective line of defense for some of the more virulent diseases.
SIU faculty also conducts clinical, translational and basic science research into the origins and evolution of infectious diseases to advance studies for future treatments.
