ObjectiveTo determine the duration of SARS-CoV-2 persistence in quarantine hotel environments.Methods39 Patients confirmed by RT-PCR were included. We collected clinical features, laboratory test results, smear sample information, and room information. Genome sequencing phylogenetic analysis conducted. analyzed factors associated with environmental contamination.ResultAmong 39 COVID-19 cases, 10 asymptomatic 37 imported from aboard. 271 swab samples surfaces related to observational patients. Eighteen seven patients positive. The highest contamination rates occurred on cups (100%), followed hand sink (12.82%), toilet seat flush (7.89%), telephone (5.56%), bedside table floor drain (5.41%). results showed that surface was cycle threshold values for (P = 0.01) sampling interval time after cases left their rooms 0.03). wet status site 0.01).ConclusionOur findings might be attributed viral load respiratory tracts rooms. Moist more vulnerable remaining RNA-positive. Our study highlights importance implementing strict chemical disinfection strategies
