Even if you have unprotected sex with an AIDS patient, you can still get infected with AIDS. Don’t take any chances, the probability of infection varies depending on the level of the virus. In addition to sexual intercourse, blood can also cause the transmission of AIDS. If you share syringes with others, or share personal items such as toothbrushes, razors, and shavers, you may be infected with AIDS. If you have your teeth cleaned, extracted, tattooed, or eyebrows tattooed in an irregular medical facility, you can also get AIDS. Mother-to-child transmission can also cause HIV infection. A mother with HIV can transmit the virus to her baby during pregnancy.
