We don’t have a single documented case of covid-19 transmission from surfaces. Not one.
So why, then, are we spending a small fortune to deep clean our offices, schools, subways and buses?
Business leaders, school districts and government officials often ask us whether people are over-cleaning in response to the pandemic. The short answer is yes. The reality is that the novel coronavirus spreads mainly through the air. Especially with regular hand-washing, there’s no need to constantly disinfect surfaces.
The best analogy we’ve used for how this virus is spread is to think about a smoker. If you’re near a smoker outside, you may not notice the smell, especially if you’re not standing too close. But if you’re indoors, you could definitely detect it, even if you’re across the room, depending on how far away you are and how well-ventilated or filtered the air is.
How much could you protect yourself from that smoke by scrubbing down countertops, doorknobs and all the other surfaces in the room? Not much. Shared air is the problem, not shared surfaces.
