Scientists at CDC and other laboratories have detected a previously unrecognized coronavirus in patients with SARS.
This new coronavirus is the leading hypothesis for the cause of SARS, however, other viruses are still under investigation as potential causes.
Coronaviruses are a group of viruses that have a crown-like (corona) bottle-cap appearance when viewed under a microscope. These viruses are a common cause of mild to moderate upper-respiratory illness in humans and are associated with respiratory, gastrointestinal, liver and neurological disease in animals. CDC scientists isolated a virus from the tissues of two SARS patients and then used several laboratory methods to characterize it. Examination by electron microscopy revealed that the virus has the distinctive shape and appearance of coronaviruses, and genetic analysis suggests that this new virus does belong to the family of coronaviruses but differs from previously identified family members.
