Infectious Diseases

Call us: 815-599-7740

An infectious disease specialist works to diagnose and treat disease caused by a biological agent (e.g. virus, bacterium or parasite), as opposed to physical (e.g. burns) or chemical (e.g. intoxication) causes. Examples of infectious diseases include influenza and pertussis (whooping cough).

Many of our specialty care offices require a referral from primary care for your initial visit, so if you're already an FHN patient, you may need to contact your primary care provider for more information. If you're new to FHN, or don't have a primary care provider, call the number above and you'll have a primary care appointment before you hang up the phone!* Thank you for choosing FHN!
