If you have a cut on your lips and kiss someone that have an AIDS are u prone to get the virus?

If the cut or laceration has exposed blood (bodily fluid) on both folks, it is possible to transmit HIV (the virus that can lead to AIDS if unchecked). However, it is more likely to transmit hepatitis. HIV is a very fragile virus that dies in contact with the air once outside the body. However, if the fluids exchange in very intimate contact where air is not present (pressing lips and rubbing frantically will do it), the chances for infection increase. There is no current evidence (in the 20 plus years we have been studying the disease transmission modes) that saliva transmits enough of the viable virus to cause infection.

There will be people that deny this, but if you have open sores, and the other person does, too, there is a possibility. Consensus seems to be that saliva does not carry the virus, but it seems prudent to not share body fluids at all.

It is not normally transmitted through kissing, but you have an increased posibility with a cut lip.

it matters how you kiss hem If you two made out and french kissed then yes there is a chance. But if it was just a kiss on the cheek, there is a very low chance.

Causes of HIV/AIDS
Cause of HIV/AIDS: AIDS is caused by the human immunodeficiency virus (HIV). By killing or damaging cells of the body's immune system, HIV progressively destroys the body's ability to fight infections and certain cancers. People diagnosed with AIDS may get life-threatening diseases called opportunistic infections, which are caused by microbes such as viruses or bacteria that usually do not make healthy people sick. 1

Cause statistics for HIV/AIDS: The following are statistics from various sources about the causes of HIV/AIDS:

57.5% of adult males with AIDS contracted it through sex with other men in the US 2001 (US Centers for Disease Control and Prevention, US Census Bureau)
24% of adult males with AIDS contracted it through injecting drugs in the US 2001 (US Centers for Disease Control and Prevention, US Census Bureau)
9.5% of adult males with AIDS contracted it through heterosexual contact in the US 2001 (US Centers for Disease Control and Prevention, US Census Bureau)
38% of adult females with AIDS contracted it through injecting drugs in the US 2001 (US Centers for Disease Control and Prevention, US Census Bureau)
59% of adult females with AIDS contracted it through heterosexual contact in the US 2001 (US Centers for Disease Control and Prevention, US Census Bureau)
Cause details for HIV/AIDS: HIV disease is characterized by a gradual deterioration of immune function. Most notably, crucial immune cells called CD4+ T cells are disabled and killed during the typical course of infection. These cells, sometimes called "T-helper cells," play a central role in the immune response, signaling other cells in the immune system to perform their special functions.

A healthy, uninfected person usually has 800 to 1,200 CD4+ T cells per cubic millimeter (mm3) of blood. During HIV infection, the number of these cells in a person's blood progressively declines. When a person's CD4+ T cell count falls below 200/mm3, he or she becomes particularly vulnerable to the opportunistic infections and cancers that typify AIDS, the end stage of HIV disease. People with AIDS often suffer infections of the lungs, intestinal tract, brain, eyes and other organs, as well as debilitating weight loss, diarrhea, neurologic conditions and cancers such as Kaposi's sarcoma and certain types of lymphomas.

Most scientists think that HIV causes AIDS by directly inducing the death of CD4+ T cells or interfering with their normal function, and by triggering other events that weaken a person's immune function. For example, the network of signaling molecules that normally regulates a person's immune response is disrupted during HIV disease, impairing a person's ability to fight other infections. The HIV-mediated destruction of the lymph nodes and related immunologic organs also plays a major role in causing the immunosuppression seen in people with AIDS.
