If a person with ads scratches you will you have ads?

[S. Sheppard]

AIDS spreads through direct contact with the infected body fluid. Scratching cannot spread it, unless both parties are bleeding and the infected blood enters the system of the uninfected person.
Saliva, urine, vomit, and snot don't contain enough of the virus to infect someone, unless it has blood mixed in it. Unprotected sex, dirty needles, blood/transfusions, and pregnancy/ childbirth/ breastfeeding are some ways you can contract AIDS.
