Brownstein plans to take the system global and expand it to other diseases.

He currently runs another website, HealthMap, that for seven years has tracked outbreaks worldwide.

He says as a graduate student he grew weary of begging health ministers for information. “And so we had this idea, well, what if we mined the Web looking for clues about outbreaks via news, social media, blogs, chat rooms, discussion forums," he said.

In Haiti's deadly 2010 cholera outbreak, HealthMap's automated Web searches provided early information on the trajectory of the disease.

Today, he is following an ebola outbreak in Uganda. “We think there's opportunities to really track emerging infectious diseases with these tools," he said.

Tools that pinpoint where diseases are occurring now.
