In men, the first negative test took 24 ± 9 days (range: 7 -46) and in women it took 25 ± 9 days (range: 9 -44), P>0.05, In an attempt to understand why some patients maintained positive tests for longer, we correlated the detection of SARS-CoV-2 RNA with the host immune response to virus infection. The lack of information regarding persistence of virus RNA and infectivity, disease severity and immune response, supports the current guidance of viral clearance confirmation prior to patient transference out of dedicated COVID-19 wards and of ending isolation in mild illness patients.	./cache/cord-339782-rybjc58j.txt	./txt/cord-339782-rybjc58j.txt
