I'm laughing a little, but only a little. I am a sceptic of this virus, but only to the extent that I think it's overblown. It will kill people, sure, but not in a different way than the regular flu. It's the martial law over a flu that take issue with. For that reason, I think you're justified in being paranoid. The risk factors are there and you should be cautious even though I still believe you would be very unlucky to actually die. My advice is kind of lame because I'm a lolbertarian. I advocate letting all people make their own choices and trying not to tell people how to make theirs. I actually agree the kid could make some good money right now in a grocery store. Demand is high for workers and a 15 year old is absolutely not going to die on the flu. I think all you can do is express your concerns to your fiance and then make your own choices as appropriate. From the perspective that the flu could be deadly, it is a no-brainer to distance yourself from the mother and possibly from your fiance if they are not interested in distancing themselves. In saying that, they should be receptive to concern coming from such a justified position as yours and should be willing to make compromises for a few months, because it is temporary. I would be shocked if your fiance didn't take your side. Failing that, you can only do what you have control over. If people aren't going to move for you, and you have genuine mortal concerns, all you can do is make your own choices in the interests of your own safety.
