Understanding Illinois’ county health departments is key to accessing vital public health resources. With over 150 county health units statewide, these agencies deliver essential services tailored to local communities. This guide explores what each department offers, how to connect, and why local health support matters.

What Are Illinois County Health Departments?

Each of Illinois’ 102 counties operates its own health department, funded locally and guided by state standards. These departments serve as frontline public health partners, providing disease prevention, environmental safety checks, maternal and child health programs, immunization services, and emergency preparedness.

Founded on trust and community focus, county health departments combine modern medical expertise with deep local knowledge. Their work directly impacts residents’ daily well-being—from monitoring water quality to offering free or low-cost screenings.

Key Services Offered Across Counties

While each department has unique programs, common services include:

• Vaccination Clinics: Seasonal flu shots, COVID-19 boosters, and childhood immunizations are routinely available.
• Disease Surveillance & Control: Prompt response to outbreaks, contact tracing, and public alerts during health emergencies.
• Environmental Health Inspections: Ensuring safe food handling, clean drinking water, and housing conditions.
• Maternal & Child Health Programs: Prenatal education, breastfeeding support, and early childhood wellness screenings.
• Chronic Disease Management: Diabetes education, smoking cessation, and hypertension control initiatives.

These services are designed to address both immediate health needs and long-term wellness goals, reflecting a proactive public health approach.

Accessing county health services is simple and often free or low-cost. Most departments operate physical offices, offer mobile clinics, or provide telehealth options. Here’s how to find and use them:

• Visit the Local Health Department Website: Search online using your county name followed by ‘health department’—sites typically include service maps, contact info, and appointment booking.

County health departments are critical in bridging gaps between state policy and community needs. By leveraging local data and relationships, they deliver personalized, culturally competent care that national programs often cannot match.

Their role extends beyond clinics: they educate through school programs, advocate for clean air and water policies, and support vulnerable populations. This trusted local presence builds confidence and drives better health outcomes.
