           Interviewing patients and tracking their contacts during a disease’s incubation period is an effective
           way to contain the spread of disease. The incubation period for SARS is usually 2 to 7 days.



               Lastly, the symptoms of SARS seem to appear before the person is
            infectious. So SARS patients can be identified and isolated before they
            release the SARS virus into the air with every cough. This is different
            from many other diseases. For example, with the flu, people feel well
            but are infectious before symptoms appear. They spread the flu virus a
            full day or more before they realize they’re sick.

            People are not the only passengers on commercial planes. Nearly
            one and a half billion live animals—including mammals, birds, fish,
            reptiles, amphibians, and insects—reached the United States from
            countries around the world between 2000 and 2006. And those are just
            the legal imports. The Wildlife Conservation Society estimates that
            illegal animal trade is a $6 billion global industry. They think that tens
