Yes, and not even the Group A Strep variant, a somewhat more common cause of necrotizing fasciitis, has anything in particular to do with Africa (more than anywhere else). I have some personal history with necrotizing fasciitis and am a bit lighter for the experience.
I have had staph infections twice. The first time I didn’t know what it was and waited almost too long (I thought I had sprained my thumb - red, swollen, hurt). I was on I.V. antibiotics for three days.
The second time I figured it out quickly and he gave me some pills and sent me on my way. I suppose these bugs are all a bit different, but the doc said the staph bug is on your skin all the time. Both times I just had dried, cracking skin - perhaps some fine scratches, but had been working outside in the dirt, so I’m thinking it was something in the dirt (two very different geographical locations).
