Detect Epidemics Before They Start

From Wired News:

Back in May 1993, as a medical resident at the University of Arizona, Mark Smolinski volunteered for a shift with the state's Department of Health. Right after he started, Arizona and neighboring states were struck by a deadly outbreak of an unidentified respiratory illness. The young doctor found himself face-to-face with an emerging epidemic, part of a team that spent sleepless months struggling to contain the outbreak. "I was going from hospital to hospital trying to determine the patients' exposures," he recalls of his harrowing first assignment. "Almost all the cases were under the age of 30, and it had a very high mortality rate."

The researchers finally identified the culprit — which eventually infected 53 people, 60 percent of whom died — as a new strain of hantavirus. They pinned the outbreak on a confluence of ecological and social factors: Wet weather during an El NiƱo year spawned heavier-than-normal vegetation. That in turn fueled an unusually large population of deer mice, which harbor the virus. The victims were exposed when they rummaged through closets or gardened, inhaling dust laced with mouse droppings, urine, or saliva. The disease soon receded, but Smolinski was hooked on the rush he got from investigating outbreaks. "It seemed like a career that would never be dull," he says. "That has certainly proven true."

These days, Smolinski's business card at Google.org, the philanthropic arm of the Mountain View behemoth, identifies him simply as "threat detective." He's director of the organization's Predict and Prevent Initiative, a global health program. The 46-year-old's job is to channel money — one insider estimates up to $150 million — into projects and technologies that will help catch outbreaks like hantavirus wherever they crop up. What's even more ambitious is Smolinski's desire to push disease surveillance "two steps to the left of the epidemic curve." The strategy: Draw on Google's search acumen to predict hot spots before the first case of some imminent calamity hits the hospital.
