[Study on the RNA of severe acute respiratory syndrome (SARS) associated coronavirus in the blood and excretion of convalescent patients with SARS].
OBJECTIVE: To examine the RNA of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) in the blood and excretion of convalescent patient with SARS for prevention and treatment of the disease.
METHODS: A total of 276 samples, including plasma, urine, feces and sputum, obtained from 23 convalescent patients with SARS were studied at 3 time-points at least 21 days after the onset of symptoms. RNA was extracted and nested reverse transcription-polymerase chain reaction (RT-PCR) was carried out using SARS-CoV specific primers.
RESULTS: Among the 276 samples, SARS-CoV RNA was detected in 6 cases (38.8%) by nested RT-PCR. The positive rates of SARS-CoV RNA was 5.8% in feces and 2.9% in sputum samples but SARS-CoV RNA was not detectable in plasma and urine of all the cases.
CONCLUSION: The existence of SARS-CoV RNA in the excretion of some convalescent patients with SARS showed that the excretion from these patients should be carefully treated whilthe re-transmission of SARS by which, should be further studied.
