740 ILCS 180/2.2
The state of gestation or development of a human being when an injury is caused, when an injury takes effect, or at death, shall not foreclose maintenance of any cause of action under the law of this State arising from the death of a human being caused by wrongful act, neglect or default.
There shall be no cause of action against a health care professional, a medical institution, or the pregnant person for the wrongful death of a fetus caused by an abortion where the abortion was permitted by law and the requisite consent was lawfully given. Provided, however, that a cause of action is not prohibited where the fetus is live-born but subsequently dies.
There shall be no cause of action against a physician or a medical institution for the wrongful death of a fetus based on the alleged misconduct of the physician or medical institution where the defendant did not know and, under the applicable standard of good medical care, had no medical reason to know of the pregnancy of the mother of the fetus.
