The go to diagnosis on the show. Thing is MRSA and other types of bacteria are everywhere and 99.9% of the time when exposed to them nothing serious happens. For some reason a type percentage of the population can get a severe reaction.
That’s why I just do my own with an exacto knife here in my desk drawer...
MRSA is a heavy bacteria in the human olfactory system people have MRSA all the time it has to get into an open cut and fester in order to be deadly i went swimming with diabetic sores on my feet and had to go through 6 months of antibiotics to get rid of the crap Vancomycin saved my life
