I Have Been Treated For Cellulitus For Nearly 3 Years---I

I have been treated for cellulitus for nearly 3 years---I have been on countless antibiotics--including Vancomycin for 2 months following surgery for MYRSA. I now have the infection in my other leg and have been scheduled to see an infectious disease Dr Monday. I need to know if I am contagious--I have a special needs grandson and do not want to infect him. I have the seepage covered.
