What is HIV?

Human immunodeficiency virus is a condition that causes the human immune system to fail and allow infections and cancers to grow. HIV is caused by a slow retrovirus that causes Acquired Immunodeficiency Syndrome (AIDS). HIV infection can occur through the transfer of semen, blood, pre-ejaculate, breast milk or vaginal fluids. HIV is present within these bodily fluids as both a virus within infected immune cells and free virus particles. Important cells of the immune system such as helper T cells, macrophages and dendritic cells can become infected. Low cells of CD4+ T cells can be caused by many different methods. Cell mediated immunity is lost when CD4+ T cell opportunistic infections. When someone has an HIV risk, questions can arise about the chances of contracting the virus, the complications and possible prognosis. Read below for questions that have been answered by Experts about HIV risk.

What is the HIV risk from oral sex with no ejaculation?

The HIV risk from oral sex with no ejaculation could be low. The chance of HIV transmission was calculated in one study of a group of men. The likelihood for unprotected and receptive anal intercourse was 0.82%. The chance for insertive and unprotected anal intercourse was 0.06%. As for oral intercourse that was unprotected and receptive with ejaculation the risk was 0.04%. More studies are needed to corroborate these estimations. This is because there is only one study available to help provide the HIV risk for oral transmission. Therefore, the risk could be less than 0.04% with no ejaculation.

What is the HIV risk from non-penetrative sex?

The HIV risk from non-penetrative sexual intercourse could be low. There would need to be a mucus membrane exposure for both individuals for there to be any transmission of this virus.

What is the HIV risk from protected oral sex?

The risk for HIV from protected oral intercourse could be 0.001% or lower. The risk of transmission could be negligible because of the protection and there was no touching during ejaculation. Early HIV symptoms can be present within 2-4 weeks following transmission.
