Animal-to-human diseases could be right at home

A new map depicting where severe acute respiratory syndrome (SARS) or Ebola might erupt next highlights North America and Western Europe as likely locations.

Developed by Peter Daszak of the Consortium for Conservation Medicine in New York City, the map draws on growing knowledge of how pathogens hop from animals to people, a process called zoonosis. An estimated 75 percent of human diseases originated in animals.

"We now have a valid model for predicting zoonotic-disease emergence," says Daszak. Population density and frequency of contact between people and animals factor heavily in the new map.

Despite pervasive popular images of diseases springing from the jungle, Daszak says that "the main emerging infectious hot spots are in developed, high-latitude countries."
