WSU Health & Wellness Services: H1N1 (swine flu) has been confirmed among WSU students. If you have flu-like symptoms (fever plus cough or sore throat) and are not seriously ill, please stay home, rest, drink fluids and self-isolate until you have been fever-free for 24 hours without medication. Do not attend class. Call Health & Wellness if symptoms worsen.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed: sources confirm WSU health officials urged students with flu-like symptoms who were not seriously ill to self-isolate at home and stay away from class, but the verbatim advisory text is not preserved.
This is a public-health advisory rather than an emergency notification, reflecting the slower-onset nature of a disease outbreak.
The first five H1N1 cases were confirmed August 27, 2009, just three days after classes began on August 24.

WSU update: We estimate we have been in contact with about 2,000 students with influenza-like illness in the first 10 days of the semester. Most cases are mild. Continue to self-isolate if ill, cover coughs, wash hands frequently, and avoid close contact with others until recovered.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

Reconstructed: a university posting quoted in coverage estimated contact with about 2,000 students with influenza-like illness in the first 10 days; the surrounding advisory wording is reconstructed.
This is an update tracking the scale of the outbreak; it reinforces self-isolation guidance rather than lifting any restriction.
By September 9, 2009, 169 new suspected cases were reported in a single day among roughly 18,000 Pullman students.
Context

Background

Washington State University's Pullman campus drew national attention in early September 2009 as the site of the largest college swine flu outbreak in the country. Classes began August 24; the first five H1N1 cases were confirmed August 27, and within ten days the university estimated about 2,000 students had influenza-like illness, pushing the state's reported case rate far above the national average. Rather than close, WSU asked students with mild symptoms to self-isolate and managed the outbreak through health advisories. Nearly all cases were mild, with no deaths. The episode became an early case study in how a residential campus communicates during a slow-onset public-health emergency, using advisory messaging rather than the rapid emergency-notification model built for active threats.
Analysis

Key Findings

WSU Pullman recorded the largest U.S. college H1N1 outbreak of fall 2009, with an estimated 2,000+ ill students in the first 10 days
The first five cases were confirmed August 27, 2009, three days after classes began
The university relied on public-health advisories urging self-isolation rather than closing campus
Nearly all cases were mild with no deaths, illustrating advisory-style outbreak communication versus rapid emergency notification
Outcome
More than 2,500 suspected cases were reported during the first two weeks of the semester, but nearly all students had mild symptoms and recovered in three to five days. There were no deaths and only a few hospitalizations.
