The odors of healthy people

Malaria infection does not create new volatile chemicals in the body, but alters the amounts—up or down—of volatile chemicals that are already present in the odors of healthy people.

"It is interesting that the symptomatic and asymptomatic infections were different from each other as well as from healthy people," said Mark C. Mescher, adjunct professor of biology, Penn State, and professor of environmental systems science, ETH Zurich.

This difference among infected, infected asymptomatic, and healthy individuals may eventually lead to tests capable of rapidly and accurately identifying infected people, even those without symptoms.
