That'll need a reference. It's only a few weeks since a worker was infected in a one-person workshop[1], from the guy working there two days earlier. Testing showed that it was the exact same (rare) virus strain and the only explanation was that the second guy got infected from using the same tools as the first guy (not infected _through_ the hands of course, but presumably by touching his face afterwards. As one does).
(Keeping surfaces clean is the most important part, otherwise you'll have to clean your hands every time you touch something. As for myself I've become very self-conscious about what I touch.)

Kids, highest risk group for this flu virus... right?
Psychologically, they are, and I think you know that.
We're still using lots of hand sanitizer here, because the combination of masks, social distancing, and hand sanitizer seems to work. Though, we could be mistaken about the relative effectiveness/necessity of the three measures. My office building has hand sanitizer dispensers in the entryway.
Yes, it's primarily a respiratory virus, but the cost of hand sanitization is pretty low and the virus remains infectious on most surfaces for several hours. Here in Hong Kong, we're one of the most dense cities on Earth, with a lot of public transit use, so surface contamination may be more of an issue here than in other places.
