Breaking the Chain: Understanding and Combatting Tuberculosis in DuPage County

News Flash: DuPage County Health Department Celebrates World Day

On March 24, the DuPage County Health Department is celebrating World TB Day to raise awareness about tuberculosis (TB) prevention and treatment methods. In 2023, there were 41 active TB cases reported among DuPage County residents, although numbers have varied in previous years. The DCHD plays a crucial role in preventing and controlling communicable diseases like TB by collaborating closely with healthcare providers and patients.

Tuberculosis is a contagious disease that can be fatal if left untreated. It 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 developing TB disease. Treating latent TB infection is an effective way to prevent the development of active TB disease.

The DCHD’s TB 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.
