Here we report a case of COVID-19 who met the criteria for discharge but was tested positive for SARS-CoV2 again 10 days after discharge. There her nasal swab was obtained, and SARS-CoV2 was tested positive with real-time reverse-transcriptase polymerase-chain-reaction (RT-PCR) assay targeting ORF1ab and N gene of virus genome. RT-PCR examination for SARS-CoV-2 was performed on day 10, 11 and 14, and all 3 tests were negative. Her symptom was not relieved on day 25, so her nasal swab was obtained and the test for SARS-CoV-2 was positive again. Previous study on SARS-CoV showed that virus load could be detected for more than 10 weeks after disease onset.	./cache/cord-306598-xe0pq0ik.txt	./txt/cord-306598-xe0pq0ik.txt
