The number of confirmed coronavirus cases in Illinois has risen to 25, Gov. J.B. Pritzker announced Wednesday.

The six new cases are a Lake County man in his 50s, and five Chicago/Cook County cases: a man in 80s, two men in their 70s, a woman in her 50s and a man in 40s, according to Dr. Ngozi Ezike, director of the Illinois Department of Public Health.

Dr. Allison Arwady, commissioner of the Chicago Department of Public Health, said she expects the number of cases in the city and state to “continue to grow.”

Earlier Wednesday, Mayor Lori Lightfoot announced that the city’s St. Patrick’s Day parades would be postponed due to concerns over coronavirus.
