Tracking Down the Source of SARS

NPR's Richard Knox looks at human diseases that are thought to originate in animals. SARS is one such disease. So is a bird flu now affecting Europe. Crucial to finding the original cause is finding the first few human cases of the disease. In southern China, investigators say the trail to the first SARS cases is growing cold because of initial government resistance to outside help.
