The team has found the novel coronavirus can stay up to nine days on common surfaces, based on their comprehensive analysis of studies about similar pathogens, such as the SARS coronavirus and MERS-CoV. The results show that the viruses can persist or survive on surfaces and remain infectious at room temperature for nine days, with an average lifespan of four to five days.
Not saying it's not the case but tests have not shown it stays on surfaces for 9 days. They are analysing previous studies of other viruses.
