WSU flu outbreak provides rare study material
Date:8/25/2014

PULLMAN, Wash.Five years ago this month, one of the first U.S. outbreaks of the H1N1 virus swept through the Washington State University campus, striking some 2,000 people. A university math and biology professor has used a trove of data gathered at the time to gain insight into how only a few infected people could launch the virus's rapid spread across the university community.

The fall 2009 semester hadn't even started when the first cases came in to the university's Health and Wellness Services clinic11 one day, and just two days later, 47. Not two weeks later, doctors and nurses in the clinic saw 164 H1N1 patients, attending to a total of nearly 1,000 sick people, plus hundreds more by phone. They ran out of Tamiflu, an antiviral medication.

The flu wasn't as intense as feared. People felt awful for three or four days and were close to normal within a week. No one died.

Still, WSU took on the national distinction of having one of the first and largest H1N1 outbreaks at an American college. The epidemic also gave Elissa Schwartz, an assistant professor of both math and biological sciences, an ideal phenomenon for scientific study.

At the time, Schwartz was teaching students about the behavior of epidemics in a closed population. She had her students search the scientific literature looking for studies that tracked actual epidemics in closed populations, which have no movement in our out. They found very few.

But they had a fairly closed population in Pullman, more specifically College Hill, where many students live, often in shared housing. When they do leave the house, they're on campus, in close proximity to more people. With the exception of semester breaks and the occasional road trip, they rarely leave.

"We thought, 'Oh, if we can get data on this, then that will be real live data, not simulated data, on the actual number of infections in this community,'" Schwartz recently told Washington State Magazine. "And it turned o
