I really didn't think it's that far-fetched. The US army did mind-altering experiments with LSD and there has been research into developing weapons that harm people but don't do damage to structures. And, if there is doubt about the government's willingness to experiment on civilian populations, we can look to Tuskegee where infected patients were observed and not treated. Lied to so they'd go on with their lives and infect their spouses and children. I just put it all together in my peculiar head and came up with this story.

Thanks for your comment. I appreciate it very much.
