hi a friend came to my house last week. he may have hiv. he drank water from a cup and left a little in it. my mother took the cup and started washing it using tap water. later I came to know that my mother had a fresh cut on her hand while she was washing the cup. this is really worrying me as that person had cuts in his mouth. what should I do? if it was me I could have got tested but I do not want to worry my mother if it is just anxiety
