It's Difficult to Get HIV From Casual Contact
FACT. HIV is not spread from casual contact, air, water, sharing dishes, toilet seats, or saliva. The virus cannot live for long periods outside the body. HIV is spread through bodily fluids including blood, semen, and breast milk and it is possible to spread the disease by having unprotected sex, and sharing needles. Less commonly, HIV can be passed on through breast milk, blood transfusions (this is rare because the blood supply in the U.S. is carefully screened), and being stuck with an HIV-contaminated needle or object.
