. . . findings show that SARS-CoV-2 is actually quite similar to SARS-CoV-1 in terms of stability in the environment. This means we can learn from our experiences with SARS in 2002-2004 to gain insights into infection control, especially in healthcare settings. On the other hand, it indicates that the major differences in the epidemiology of these viruses probably arise from other factors—especially the ability of SARS-CoV-2 to be transmitted by people not exhibiting clear symptoms.”
