New Illinois Public Health Laws Take Effect in 2026, Including Overdose Reporting Measures (Springfield, IL) – A slate of new Illinois laws aimed at strengthening public health protections, improving data collection and addressing long-standing health disparities will take effect beginning Jan. 1, 2026, state health officials announced.
The measures, approved by the General Assembly during the 2025 legislative session, cover a wide range of issues including overdose tracking, maternal health, reproductive care access on college campuses, emergency allergy treatment and the creation of a new “One Health” commission within the Illinois Department of Public Health.
One of the most significant changes is House Bill 3645, which expands overdose reporting by authorizing the transmission of limited information from first responders to the state. The law allows IDPH to submit data on suspected overdoses to the Overdose Detection Mapping Application Program, known as ODMAP.
State officials say the data will help public health agencies identify overdose spikes in real time, allowing for quicker intervention and more effective deployment of resources.
“Improving overdose reporting gives us better tools to respond to a public health crisis that continues to affect communities across Illinois,” IDPH Director Dr. Sameer Vohra said in a statement.
Several other public health-related laws will also take effect at the start of the year:
Senate Bill 119 requires health care professionals to test pregnant patients for syphilis during their first prenatal visit and again during the third trimester. Lawmakers say the change is intended to prevent congenital syphilis and ensure early treatment.
House Bill 3709 mandates that public colleges and universities provide students access to health care professionals who can prescribe and dispense contraception or medication abortion, or provide information on how to obtain those services.
Senate Bill 291 establishes a state One Health Commission within IDPH, recognizing the connection between human health, animal health and environmental conditions. The commission will focus on issues such as zoonotic diseases, insect-borne illnesses, antimicrobial resistance and emerging public health threats. It will be co-chaired by the IDPH director and the president of the University of Illinois System, or their designees.
House Bill 2462 authorizes IDPH to issue a standing order allowing organizations and trained individuals to obtain and administer epinephrine in cases of severe allergic reactions or anaphylaxis.
Another measure, House Bill 2517, requires health care professionals who provide maternal health services to complete a one-hour implicit bias training course as part of their license renewal. Supporters say the requirement is intended to address persistent racial and ethnic disparities in maternal health outcomes.
In addition, Senate Bill 1950 — the Medical Aid in Dying Act — is scheduled to take effect in September 2026. The law allows certain terminally ill patients to request medication to end their lives under specific medical and legal guidelines. Physicians who participate will be required to submit confidential documentation to IDPH following a patient’s death.
IDPH officials said the department will work with health care providers, first responders and other stakeholders over the coming months to ensure the new laws are implemented smoothly and effectively.
“These initiatives represent a comprehensive effort to improve health outcomes and protect Illinois residents,” Vohra said.
