If the skin is intact, generally, contact with the blood of an HIV-infected person will not transmit the virus. However, if the skin is damaged and comes into contact with the blood of an HIV-infected person, there is a possibility of transmission. Additionally, the mucous membranes of the body, such as in the eyes, inside the mouth, and various cavities, can potentially get infected with HIV if they come into contact with HIV-infected blood. If these mucous membranes are damaged, the risk of HIV infection significantly increases.
