SPRINGFIELD – A measure addressing increased congenital syphilis cases in Illinois championed by State Senator Karina Villa advanced Wednesday.

“As we continue to see a trend in rising congenital syphilis cases across the country, it is critical that our laws reflect best practice to ensure the health and safety of an expecting parent and their child,” said Villa (D-West Chicago). “The earlier it is caught, the better it can be treated.”

Senate Bill 119 would require the second syphilis test conducted on pregnant individuals to be done between 27 and 32 weeks of pregnancy to ensure treatment can begin at least 30 days before delivery. The measure would also expand authorization to administer the test to health care professionals who are qualified in addition to physicians.

According to the Illinois Department of Public Health, congenital syphilis cases have increased by 255% since 2020. In 2023, 103 cases were reported across the state compared to 29 cases in 2020.

“Left untreated, congenital syphilis poses serious health risks to pregnant individuals and their children,” said Villa. “Ensuring that testing and treatment is provided at the appropriate time is crucial in preventing any possible harm.”

Senate Bill 119 passed the Senate on Wednesday.
