Objective: To confirm the new isolated coronavirus and SARS patients. Methods: Immunofluorescence staining was performed with IFA diagnostic reagent to detect serum specific antibodies in 72 patients with SARS clinically diagnosed in 3 hospitals in Guangdong during the period from 2000 to 2004, and to directly participate in the treatment of patients with SARS However, serum samples of 109 health workers who did not get infected at the end of the epidemic period were taken as normal control group with 70 healthy people during the epidemic. Results: Serum specific IgG was positive in 62 out of 72 cases of SARS. Serum specific IgG and IgM were negative in 109 close-matched and non-infected medical workers and 70 healthy SARS patients . Conclusion: SARS coronavirus is the causative agent of SARS in Guangdong
