I was out on my walk yesterday morning and spoke to a middle-aged guy laden with bags from Asda - exchanged a few friendly words (from a three llama distance) - and then he just muttered, " I'm not bothered - if you get it, you get it."
As I walked away, I reminded him that him being infected could infect others. He just looked at me blankly.
(A very rude word popped into my mind but I restrained myself.)
