(Guo et al., 2020; These researchers confirmed the virus by real time reverse transcription polymerase chain reaction (RT-PCR), which typically performs deactivation, nucleic acid extraction, and RT-PCR amplification of the collected samples. Samples were collected from seven sites: 1) bedrail; 2) bedside cupboard; 3) chairs; 4) door handles of the bathroom; 5) light switches; 6) remote controller or beeper; 7) fingertip of electrocardiograph (ECG) monitoring. We successfully applied an extraction-free SARS-Cov-2 isothermal amplification detection method to on-site analysis of surface contamination by COVID-19 patients in wards. Among 31 cases collected from 18 March to 27 April of 2020, 72.7% reported positive amplifications on the ECG fingertip, indicating that this surface is an important hygiene site. -The presence of SARS-CoV-2 in wards was confirmed by nucleic acid isothermal amplification.	./cache/cord-350236-7fit8q1s.txt	./txt/cord-350236-7fit8q1s.txt
