Contracting infectious diseases at the gym/kwoon?
While sparring or rolling, how do you protect yourself from contracting something from another student/gym mate? It's quite easy to get cut or to cut someone while sparring or rolling, increasing chances of cross contamination. I understand it is not very likely, but the chance is still there.
Now a days, with increased numbers in HIV or Hepatitis, there is no way to know if someone is a carrier, even if you know them well.
Not too mention the different types of communicable skin diseases, such as herpes, or mrsa.
What steps do you take to protect yourself from contracting something during training? What steps does your gym/kwoon/dojo take to protect you as a student.
What about tournaments? MMA or other full contact events?
I post this thread, not because I have an answer, but because it is a legitimate question. One that I hope experienced martial artists, students and teachers alike may share in there ideas on how to protect oneself.
What can be done, and what do you do?
