OK, I did a search; I am pretty sure this has been covered before and I will justly get flamed, but if not I have a question. I just started kickboxing and BJJ at a local gym. I am still too much of a beginner at kickboxing to seriously spar (I was looking at the more experienced guys going at it and I would have been instantly destroyed,) but I have been grappling pretty intensely.
Yesterday I was grappling and noticed some blood on my foot; it turned out that my partner had split a toenail and was bleeding. The blood was on intact skin so I didn't think anything about it and we went right back to grappling, but after the class I started to think about the health issues being bled on might cause. Now, I'm not paranoid and this certainly isn't a "oh noes, b100d!" thread, I just was wondering if this is something I should be concerned about. I know that this will certainly happen again, especially when I start seriously sparring, so I was thinking of talking to my doctor and perhaps getting vaccinations against some of the diseases I would be most worried about (like hepatitis.) But then I think I am just being a stupid noob and that I shouldn't worry at all. Am I an idiot for thinking about this?
