Case series and systematic review of literature	2020-10-10		.txt	text/plain	6678	441	54	Criteria for patients' selection were diagnosis of SARS-CoV-2 infection [5] ; the subsequent meeting of criteria for hospital discharge (improvement of symptoms and two negative swabs collected at least 24 h apart) [4] ; and a positive respiratory sample collected after discharge. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement protocol [8] , a systematic review has been performed concerning the patients with a diagnosis of COVID-19 that, after clinical and virological recovery, presented a new positive respiratory sample (swab, sputum, saliva, tracheal aspirate, or BAL). The patient was discharged in good clinical conditions with indication to repeat quarantine and swab tests that came negative for SARS-CoV-2 (Allplex™ 2019-nCoV Assay) on April 27 and 28 (Fig. 1b) .	./cache/cord-269726-z0frgm7s.txt	./txt/cord-269726-z0frgm7s.txt
