It can *survive* on surfaces for a long enough period of time for it to seem possible. But I think viral load is important and it might not practically be a serious vector for most people and most surfaces, particularly those that are commonly disinfected. It’s amazing how our knowledge went from symptomatic/surface? to pre-symptomatic/aerosol? transmission.
While I agree that that is the way that the current mainstream opinion moved, I think we should not suggest that pre-symptomatic transmission and aerosol transmission or symptomatic and surface transmission are necessarily linked.
