Tracking Disease from Space

In only twenty years, Lyme Disease has become the most common insect borne disease in the United States. Transmitted by deer ticks, it can cause anything from a rash to severe arthritis. NASA scientists, working with colleagues, at the New York Medical College have begun to use satellite images to help identify high-risk areas for deer tick infestations. Mel Averner of NASA's Global Monitoring and Disease Prediction program expects these techniques will also help combat such killers as malaria and yellow fever.
