Yeah, I feel the same way.
I work in genetic research and it always strikes me how easy it would be to put together something really bad. Never mind gene splicing and creating the next pandemic; basic biology knowledge and some run of the mill bacteria (like the ones on everyone's skin) and you have the potential to make hundreds or thousands of people sick.
Though as stated in several previous posts, there is really nothing anyone can do about it. Prepare for this like everything else you can think of and hope you can learn about it before you (and your family)are infected, then hunker down.
