That's about 5 miles from my house, and I used to work on that base. However, that case doesn't worry me.
If I were concerned, I'd be concerned about 1) the numerous meetings I attend, which usually involve 10-30 people in small conference rooms; 2) riding the DC metro every day (yecch); 3) or my wife, who is a kindergarten teacher and works in a germ farm every day.
