cord-253245-433mg0ke	Gao, Zhiru	A systematic review of re-detectable positive virus nucleic acid among COVID-19 patients in recovery phase	2020-08-05		.txt	text/plain	1854	100	55	A recent study reported that four medical workers aged 30-36 years who had re-detectable positive (RP) for SARS-CoV-2 within 5-13 days after being cured and discharged, indicating that some of the recovered patients may still be virus carriers, which caused widespread concern (Lan et al., 2020). Although the results of the three nucleic acid tests were negative for the patient, there were viral residue in the lungs, so even if the patient was discharged, we supposed that virus would transfer positive again after a period of time (Yao et al., 2020) . In addition, initial studies reported that the SARS-CoV-2 RNA could be detected in the feces of 81.8% recovered patients (54/66), even in those with negative throat swabs (Ling et al., 2020) . In other words, even if sometimes the virus nucleic acid tested by RT-PCR is positive in the recovery phase of COVID-19, it will not cause a more serious condition, and antiviral therapy may not be required in most patients.	./cache/cord-253245-433mg0ke.txt	./txt/cord-253245-433mg0ke.txt
