Firstly, we analyzed the possible sites of infection in hospitalized patients with COVID-19 by detecting viral RNA with 12 different types of specimens, including nasopharyngeal swab, oropharyngeal swab, sputum, bronchoalveolar lavage fluid (BALF), stool, anal swab, urine, peritoneal dialysis fluid (PDF), blood, sweat, cerebrospinal fluid (CSF) and corneal secretion. The 20 discharged cases of COVID-19, the criteria [12] for which was the SARS-CoV-2 virus RNA detection negative in two consecutive respiratory specimens (at least 1 day of time interval of sampling) for patients who have reached the standards of isolation period (14 days) after clinical cured, during the isolation period were selected to detect SARS-CoV-2 RNA with multiple specimens including nasopharyngeal swab, oropharyngeal swab, sputum, stool, anal swab, urine and blood.	./cache/cord-274536-fv7mltj7.txt	./txt/cord-274536-fv7mltj7.txt
