Confirmed Threat

On November 19, 2018, the day after University of Maryland freshman Olivia Paregol died of adenovirus-related pneumonia, the CDC confirmed the strain on campus was the more virulent adenovirus 7. UMD's University Health Center notified the campus community within 24 hours that adenovirus had been confirmed and identified five other students with the virus. The outbreak ultimately reached 35 cases, prompted state legislation ("Olivia's Law"), and a lawsuit alleging the university failed to alert students earlier despite knowing of the first case on November 1.

INITIAL ALERTEmail
Dear University of Maryland Community: I am writing to inform you that a University of Maryland student passed away yesterday from complications of an illness. I extend my deepest sympathies to the student's family and friends. The University Health Center has been working with the Maryland Department of Health and the Centers for Disease Control and Prevention to investigate the cause of illness. The CDC has now confirmed that the cause of illness in this and several other cases on our campus is adenovirus, specifically a strain known as adenovirus 7. Adenovirus is a common virus that usually causes mild cold- or flu-like symptoms. In rare cases, adenovirus 7 can cause more severe respiratory illness, particularly in people with weakened immune systems. As of today, the University Health Center is aware of six confirmed cases of adenovirus on our campus. We urge any student experiencing flu-like symptoms — fever, cough, sore throat, congestion — to seek medical care promptly and to share with their provider that there are confirmed cases of adenovirus on campus. The University is taking aggressive steps to clean and disinfect residence halls and common areas. We will continue to communicate updates as we learn more.

UPDATEEmail
Update on Adenovirus Cases: As of today, the University Health Center has confirmed 30 cases of adenovirus among University of Maryland students this semester, with at least eight students hospitalized. The University continues to coordinate closely with the Centers for Disease Control and Prevention and the Maryland Department of Health. We have implemented enhanced cleaning protocols across all residence halls and have provided detailed guidance to students with conditions that may increase their risk of severe illness. Students who are immunocompromised — including those receiving chemotherapy, taking immunosuppressant medications, or living with conditions such as Crohn's disease — are urged to consult with their healthcare provider about steps they can take to reduce their risk. If you develop fever, cough, or difficulty breathing, please contact the University Health Center at 301-314-8184 or seek medical care. Hand washing, avoiding sharing food and drinks, and staying home when ill remain the most effective prevention measures.

Context

Background

The University of Maryland adenovirus outbreak became one of the most consequential campus public health failures of the 2010s because it produced a student death, state legislation, and lasting changes to how universities communicate disease risk. The outbreak began in early November 2018, with the first case identified by the University Health Center on November 1. Olivia Paregol, an 18-year-old freshman from Howard County, Maryland, who had Crohn's disease and was taking immunosuppressants prescribed by the same University Health Center, sought care for flu-like symptoms on November 2 — one day after UMD's first case was identified. She was not tested for adenovirus, was sent home, and ultimately died at Johns Hopkins Hospital on November 18. The CDC confirmed the strain as adenovirus 7 — the same strain that had killed 11 children at a New Jersey nursing home earlier in the fall of 2018 — on November 19, and UMD's University Health Center sent its first community-wide notification later that day. The outbreak ultimately reached 35 confirmed cases by mid-December. Olivia Paregol's family filed a $100 million wrongful-death lawsuit in 2021, arguing the university failed to warn students about adenovirus despite knowing of cases in the dorms. A 2019 Maryland investigation concluded that UMD followed established protocols but identified communication gaps. The Maryland legislature passed Olivia's Law, which took effect October 1, 2020, requiring all institutions of higher education in the state to submit outbreak response plans to public health officials by August 1 each year. The case is now widely cited in campus public health training as a paradigm of why timely community notification matters even when public health protocols are technically followed.
Analysis

Key Findings

First UMD adenovirus case was identified November 1, 2018; first community-wide alert was sent November 19 — an 18-day gap that became central to subsequent litigation
Olivia Paregol, an immunocompromised freshman with Crohn's disease, sought care from UMD's health center on November 2 but was not tested for adenovirus; she died November 18
Outbreak reached 35 confirmed cases of adenovirus 7 — the same strain that killed 11 children at a New Jersey nursing home that fall
Maryland passed Olivia's Law (effective October 1, 2020) requiring institutions of higher education to submit annual outbreak response plans
Outcome
1 student died (Olivia Paregol, 18, a freshman from Howard County, MD, who had Crohn's disease and was taking immunosuppressants). 35 confirmed cases on campus by mid-December. Maryland subsequently passed Olivia's Law, requiring infectious-disease response plans to be filed with state health officials.
