my question is about Diseases transmitted through sharing a drink ( namely sharing of a glass), what is one likely to contract from sharing a drink with someone ( not a common practice of mine), as well as how likely these are to occur, when sharing said glass with someone who, on the face of it seems healthy and presents no notable symptoms ( i'm mostly concerned about the more threatening and impacting conditions.... hepatitis B keeps coming back to my concern for some reason). Full disclosure is that I'm a hypochondriac, and simply need to cover my bases as to what to expect and look out for, as far as likely symptoms of the more concerning deseases and cures. thank you for your attention in this matter, Juan Castaneda
