A couple days ago, while waiting for the T, a guy about ten feet away sneezed several times without even attempting to cover his face; he didn’t even make a ‘matador’, bullshit fake effort. Because of the angle of the light and what not, I could easily see the massive spray of mucus flying out of his nose. I mean stuff everywhere. Kinda like this:

Long time readers of this blog will know my battle cry, “WASH YOUR DAMN HANDS!”, but other forms of public hygiene, such as not spraying your snot hither and yon, matter too. In fact, it’s important enough that public health departments worldwide have campaigns to encourage good public hygiene:

This is all good, but what should one do if you see someone not following basic hygiene? For the record, I did not say anything to Mr. Mucus. But should I have?
If someone is, well, very stinky, that might be unpleasant, but it doesn’t represent a health hazard (to someone else, anyway). But influenza is a serious virus. And, hell, even if you’re ‘only’ spreading the common cold, why should somebody else get sick because you are too inconsiderate to cover your face when you sneeze?
I haven’t been able to find any guidelines on what is recommended by health departments, so what do you think we should do, if anything?
An aside: Obviously, if you think he is a crazy person with a meat cleaver and looking for an excuse to use said meat cleaver, not getting hacked at is the first order of business.
Another aside: Yes, I realize that by itself, good hygiene won’t stop the spread of influenza, but, even limiting the spread would be a good thing, particularly when we’re racing the clock to get vaccinated.
