Comment: I honestly don't normally take on matters as ludicrous as commentary by people willing to make deep and unfounded assumptions...but considering the topic is my husband, I'm game.
If you wold have taken the opportunity to research Necrotizing Fasciitis before spouting off, you would find that in prior years, the bacteria most commonly occurred in individuals that were obese, and without basic hygiene skills. It is, however, frequently caused by the very common Strep A bacteria that mutates in the correct environment  (gulf waters, moist conditions). Strep A lives on all of us. Every day. Whether you live under a bridge or in the glass house you call home.  
Questioning the personal hygiene of anyone experiencing trauma like Scott and Blake begs to question the general hygiene of your values as a human.
