Learn how diseases can make you have different body odors, in this episode of Gross Science from NOVA. Doctors have known since the time of Hippocrates that diseases produce distinct odors in people. For example, typhoid makes you smell like freshly baked brown bread, and the skin of people with yellow fever smells like a butcher shop. Dogs can actually sniff out certain types of cancer. Scientists are working on creating smelling machines that could be used to detect diseases. This resource is part of the NOVA: Gross Science Collection.
