SARS virus can spread in lab animals

Virologists have found that ferrets and domestic cats can acquire and transmit the virus that causes severe acute respiratory syndrome (SARS). An independent group of researchers has determined that Chinese animal traders–particularly those dealing in wild mammals–have particularly high rates of past exposure to the virus.

Cats that researchers intentionally exposed to the virus didn’t become visibly ill, but the virus did replicate in the animals’ blood.
