I totally agree with everyone else... stay away! To be honest she doesn't sound very responsible or considerate of others if she's going to a spa this weekend!! I always keep Oskar away from others if he's got something contagious (he had hand foot and mouth a few months back and has had bronchialitis etc)... if you tell someone and they still choose to be in contact well that's at their risk. NO to your friend though and she shouldn't feel offended if you say that you prefer to wait.
