Recently, NYTimes reported that scientists are now saying that scrubbing down surfaces is not nearly as effective as focusing on improving ventilation and filtration of indoor air. In fact, there are also those saying that "there is little to no evidence that contaminated surface can spread the virus", but instead, being inside a closed/crowded space poses a much greater threat for transmission - like airports. Scientists also note that hand washing/sanitizers are still strongly encouraged, but that energy/time is wasted on surface disinfection; additionally, surface disinfection could possibly give people a false sense of security about the spread of coronavirus//the safety of being in crowded places.
Instead, there is growing evidence that suggests that the virus could "stay aloft for hours" as tiny droplets, and infecting people as soon as they are inhaled. Even the CDC has switched its stance on transmission, noting that "surfaces are 'not the primary way the virus spreads", but instead respiratory droplets.
