The woman's family accuses the hospital of negligence and wrongful death.
They claimed that she had contracted with legionnaires from another person on the same floor of the hospital, calling her death preventable.
"We had many plans, we had hobbies," Gibran Ruiz said in tears. .
Ruiz is still in mourning, recounting the life he and his wife Carol wanted before she died.
"I still wake up for a few days in complete disbelief that this has happened," he said.
According to Ruiz's Family Lawyer, 35-year-old Carol Ruiz was admitted to Memorial Hospital in the Northwest Region on October 25, 201
Her immune system is suppressed as part of treatment.
Less than a month later, she was dead after being infected with Legionnaires' disease.
"While Carol was a patient in the Northwest, she was exposed to contaminated water," said attorney Thomas R. Mulroy III of Salvi, Schostok & Prichard.
The daughter, Melain Cosme, is also involved in the lawsuit.
"I'm a senior in college and I wish she had seen me finish," Cosme said.
Attorney Thomas Mulroy stated that the northwestern hospital, which houses Ruiz – with a compromised immune system – was on the wrong floor.
Five months earlier another person contracted with legionnaires. The Illinois Department of Public Health linked the two cases at the end of 2017.
Northwest Memorial Hospital declined comment due to pending litigation.
According to an email from the Chicago Department of Public Health provided by Mulroy, Legionella bacteria were found in the sink in Ruiz's Northwestern hospital room. The letter officially states that the water temperature and copper ion levels are too low. Water temperature and ion levels can help prevent the growth of Legionella bacteria.
Gibran Ruiz said he wanted answers.
"We would like to know why, we would like to know more about what actually happened and not be silent because it says nothing," Ruiz said.
The Illinois Department of Public Health reports constantly an increase in the number of Legionnaire diseases reported in the country over the last 10 years:
