Unpacking Tuberculosis in DuPage County: Prevention, Diagnosis and Treatment Efforts

In 2023, the DuPage County Health Department (DCHD) reported 41 active tuberculosis (TB) cases among its residents. However, the numbers of TB cases have varied in past years. The DCHD plays a crucial role in preventing and controlling communicable diseases like TB by working closely with healthcare providers and patients.

Tuberculosis is a contagious and potentially life-threatening disease that spreads through the air when an individual with active TB coughs, sneezes, speaks, or sings. Those with TB are most likely to infect people they regularly interact with, such as family members or coworkers. However, TB is preventable, treatable, and curable through timely diagnosis and treatment for both active TB disease and latent TB infection.

Individuals with latent TB infection do not spread the disease to others but are at risk of developing active TB if left untreated. Those with weakened immune systems, particularly individuals with HIV, face a higher risk of TB disease. Treating latent TB infection is an effective way to prevent the development of TB disease.

The DCHD’s Tuberculosis Clinic provides services to DuPage County residents, including testing, diagnosis, and treatment for TB infection and disease. Appointments are necessary for all services, and walk-ins are not accepted. To schedule an appointment, individuals can call (630) 682-7400.
