Does Widespread Spraying or Disinfecting Kill the Coronavirus? It’s Under Debate

Would be impressive if it killed something not living.

A lot of spraying is just public health theater. How does running trucks and people through neighborhoods spraying roads and all surfaces kill any virus. It is similar to carpet bombing to eliminate rodents. I saw this first in pictures out China and wondered how effective that is and how harmful to public health and what exactly are they spraying? Bizarre. Disinfecting public surfaces like poles and seats in subways is another category. Is it benign? Does it expose workers to the virus? Does it blow a hole in public finances or simply give work to underemployed city workers. Who touches those surfaces anyways?

It's sometimes literal theater, complete with fist-pumping music and dramatic marching: https://www.youtube.com/watch?v=GiDnde-ig3A https://www.youtube.com/watch?v=GiDnde-ig3A > Workers disinfect Hankou railway station in Wuhan, which has been closed for 58 days due to the coronavirus outbreak, on Friday. The transportation hub, whose reopening time is yet to be determined, can accommodate up to 160,000 passengers in normal times. Spraying like this probably makes sense in certain circumstances, like when attempting to quickly reopen a recently contaminated area when spread is otherwise controlled, but I don't think anyone's claimed the virus can remain viable for 58 days on any type of surface.

    The most bizarre performance. What are they spraying? How do they ensure it covers most surfaces? Does the moisture in it not harm the fixtures and machinery in the building? Why is the guy in front walking with his arms in the air leading them on?

We'd be in a much better position to opine if we actually knew what they were spraying. Haven't found anything online to that effect but I've been very curious.
