The swab contacted the surface of rectal mucosa, and then turned the swab gently, and it was found that the swab had feces. After inserting the swab with fecal sample into the virus collecting tube, the swab will be broken near the turning point, the pipe cover shall be tightened and sent to the inspection immediately.
