For example, the guidelines of the National Health Commission of China state that patients must meet the following 4 benchmarks before they can be discharged: (i) be afebrile for at least 3 consecutive days, (ii) have significantly improved respiratory function, (iii) produce two negative SARS-CoV-2 RT-PCR test results at least 24 hours apart, and (iv) have significant improvement in lung GGO lesions determined by chest CT or X-ray imaging. In Table 1 , we summarize the information about patients who tested positive for SARS-CoV-2 RNA in post-discharge, follow-up examinations in China as described in the 12 published reports. Our analysis indicates that many of the discharged patients tested positive for SARS-CoV-2 RNA when feces or anal swabs were employed, even though they tested negative at the same time when nasopharyngeal or oropharyngeal or sputum samples were examined.	./cache/cord-284366-snajbvr9.txt	./txt/cord-284366-snajbvr9.txt
