No. Not contagious.
Gangrene is a serious and progressive anaerobic infection. The tissue has to be damaged for the bacteria to get in and with a reduced blood supply for the infection to progress. If untreated, gangrene becomes fatal. Are you sure she has gangrene?<br />
I have never heard of anyone walking around with gangrene.... septicaemia and death are around the corner. Gangrene has a very distinctive odour... it stinks.... Micky
Its not seriously contagious, but its rapidly fatal. if she has gangrene she won't be coming to the meetings very long. Maybe she has something else. Medical attention is advised.
You are ok as long as you have no open cut that rub's against her gang green. That is nothing to fool with. I hope she is ok.
