After witnessing Kendall Grove's gruesome staph infection video that's been floating around the Internet, it had me curious. How common is staph infections in BJJ schools? If you train BJJ, is staph a common problem among some students? Has me kinda worried, as I've been thinking of taking up BJJ but don't wanna run the risk of ever catching staph. I know there's always that chance when training on mats and grappling but would like to know if this is a common thing or more of a rare occurrence. Your insight is much appreciated. Thanks.
