Well in the arab world we have a custom that we all eat in one dish and almost eveyday the same dish which is rice with chicken or meet .. The chicken and the meat get placed in the center and rice around it .. I am a firefighter and we work 12 hour period so most of our life is at work so we eat the dish i mention for dinner and lunch everyday ,, the eating way is with hands so saliva is basically everywhere on the chicken or meat , is it possible that if one of us had hiv since we live close by a contry known by prostatution, is it possible that if one of us has blood mixed with his saliva and spred it on the chicken since that mouth hygine is poor in our culture , is it possible that he could spred the virus on the chicken and through the rice with saliva contaminated wih hiv blood?
