CONCLUSION: Our data suggest that remote (> 2 m) airborne transmission of SARS-CoV-2 from hospitalized COVID-19 patients is uncommon when aerosol-generating procedures have not been performed. 10, 11 The objectives of the present study were 1) to investigate air and environmental contamination caused by COVID-19 patients in a variety of hospital settings; 2) to evaluate the effectiveness of environmental cleaning; and 3) to examine the potential for remote airborne transmission in the absence of aerosol-generating procedures. Despite extensive surface sampling, SARS-CoV-2 RNA was not detected in the room in Hospital B (AIIR with routine surface cleansing using disinfectant wipes the patient's respiratory samples (Ct value 22.4-28.9) (Fig. 1B) .	./cache/cord-323449-r1gyjxei.txt	./txt/cord-323449-r1gyjxei.txt
