Thank you, it's so good to have the facts so clearly stated.
Living not too far from the Surrey coronavirus episode, I found a fascinating study that was done in 2018 about the potential for a virus to spread, strangely Haslemere was chosen as the potential starting point. But the significant point in the tweet I've posted is how vital handwashing is, and while I'll mention the inevitable NAMALT, the cleanliness of men in lavatories is questionable, and has the potential to spread the virus imo.
Note I am not in any way suggesting that the author has a position on the provision of single or mixed sex loos, I am noting that increased handwashing was used to illustrate successful 'infection control'. Goes off muttering, what a pile of caveats in a short post, must stop worrying about offending men people
