[Detection of SARS-CoV RNA in stool samples of SARS patients by nest RT-PCR and its clinical value].

Objective: To investigate of severe acute respiratory syndrome (SARS) convalescent stool shedding by RT-PCR.

Methods: One hundred and three stool samples from 46 SARS patients were collected on May 16th, 20th, and 23rd, 2003.
