In November 2018, Olivia Paregol's father frantically called the University of Maryland from the intensive care unit at Johns Hopkins Hospital. The 18-year-old freshman, who had lived in a mold-infested dorm, was fighting for her life and doctors couldn't figure out what was wrong. Was there anything else on campus making students sick? The director of the student health center knew of severe cases of adenovirus on campus but the public had no clue. Less than a week later, Olivia was dead from the virus and the outbreak would sicken dozens of students. It was only after her death that school officials informed the campus about the virus. Ian Paregol had more questions than answers: How long had the university known? Why didn't they tell Olivia or other students when they showed up sick at the student health center? Washington Post reporters Jenn Abelson, Amy Brittain and Sarah Larimer interviewed more than 100 people and obtained thousands of pages of medical records, hundreds of emails, text messages, voicemails and other documents to reconstruct the events that led to Olivia's death and threatened the health and safety of thousands of students at the University of Maryland campus. College officials said it would cost $63,000 to disclose internal emails about the outbreak, so reporters obtained many of those records from state and county agencies. In May, the Washington Post published ‚ÄúA Dangerous Delay,‚Äù a detailed investigation examining the outbreak of mold and adenovirus at the University of Maryland. The reporters revealed that the school waited 18 days to inform students about the virus and officials discussed ‚Äî but decided against ‚Äî notifying students with compromised immune systems, like Olivia, and those living in mold-infested dorms.
