As far as I can see, you're fine. I had the same argument with a high school teacher of mine, back when I thought I was going into public health for a career and would probably wind up in Africa. (I didn't go into public health because the politics was overwhelming, but the training remained in place.) She asked if I wasn't afraid of HIV; I told her frankly that I was more scared of Ebola than HIV, and more scared of sleeping sickness than Ebola, and more scared of drug-resistant malaria than sleeping sickness. Some folks don't know enough not to be afraid, and some folks do, and the 'enough' line is different on every person. Sadly, it's damned hard to lower that line on so many people...

It's bloody stupid. If it came down to it I'd sooner shake hands with, I dunno, Greg Louganis than someone with poorly controlled TB. There's so many more contagious diseases to worry about. HIV is not all that scary if you're careful.

People just don't know better. Gonna be a while to convince them otherwise.
