I Recently Obtained The Impetigo In My Jiu Jitsu Gym

I recently obtained the impetigo in my jiu jitsu gym just the other day. since, I have been given antibiotics and bactroban. now I know I won't be practicing at the gym because I don't want to give it to anyone else. but I'd like to stay in shape and workout on my own over the next few days until it's gone. does impetigo spread through sweat? or am I okay to jog and workout on my own until it's gone? and if not how many days after starting the antibiotics will the spot no longer be contagious?
