Over time, as HIV kills more CD4 cells, the body is more likely to get various types of conditions and cancers. At that point, the immune system is too weak to successfully respond against other diseases, infections, and conditions. Untreated, life expectancy with end stage AIDS is about 3 years. With antiretroviral therapy, HIV can be well-managed, and life expectancy can be nearly the same as someone who has not contracted HIV.

Symptoms And Treatment Of Hiv Aids

HIV is a virus that can be transmitted from someone with HIV to someone without through body fluids like semen, blood, vaginal secretions, and breast milk. HIV is most commonly passed during unprotected sex, primarily anal and vaginal sex, but is also effectively transmitted through shared needles.

HIV can also be passed from mother to child during childbirthdue to exposure to blood or vaginal fluid, or while breastfeeding. Some modes of transmission are more efficient than others.

In order for HIV to be transmitted, the virus needs to click here into contact with porous mucous membranes such as those Symptoms And Treatment Of Hiv Aids in the rectum and vaginapass through breaks and tears in tissues such as can occur during intercourseor enter the bloodstream directly such as through Symptoms And Treatment Of Hiv Aids needles. This is why HIV cannot be passed through saliva, the environment of which is hostile to the virus, or when the virus is fully suppressed undetectable in an HIV-positive person on antiretroviral therapy. By killing more and more of these cells, the body's immune defenses are weakened and eventually compromised. When the body is unable to defend itself against otherwise harmless infections, a person is said to have acquired immune deficiency syndrome AIDS. There are four conditions that must be Treatmeng for an HIV infection to take place:.

Anal sex is the predominant means of HIV transmission in the United States, occurring at a rate 18 times greater than that of vaginal sex. Little microtears that commonly occur during anal intercourse simply allow more viruses to enter the body. On top of that, many people who engage in Sy,ptoms sex will often douche before intercoursestripping away the layer of mucus that might impede HIV transmission.

These vulnerabilities help explain why infection rates in the United States are highest among men who have sex with men MSM. Studies suggest that the risk of HIV in a receptive anal partner is nearly twice that of the insertive partner The risk is further increased if the insertive partner is uncircumcised due to microbes beneath the foreskin can increasing the shedding expulsion of the virus into seminal fluids. In many parts of the developing world, vaginal sex is the primary mode of transmission, with women disproportionately affected compared to men.

Women are more vulnerable for several reasons:. This is not to suggest that the male partner is without risk, especially uncircumcised men. The bacteria-rich environment beneath the foreskin helps facilitate infection by increasing the number of white blood cells, called Langerhans cellsthat reside within the skin itself. These cells can inadvertently "capture" HIV and pull them into the body.

What are the symptoms of the last stage of HIV?

Sexually transmitted diseases STDs like chlamydiaSymptojsand syphilis can further enhance the risk in men and women, either by increasing viral shedding in people with HIV or compromising genital tissues in those without. Oral sex is an inefficient way of transmitting HIV, whether it be oral-penile sex "blowjobs"oral-vaginal sex cunnilingusor oral-anal sex "rimming".

The current scientific consensus is that HIV transmission among those who engage exclusively in oral sex is unlikely. This is not to suggest that people can have oral sex with impunity.]
