Other drugs can prevent or treat opportunistic infections (OIs). In most cases, these drugs work very well. The newer, stronger ARVs have also helped reduce the rates of most OIs. A few OIs, however, are still very difficult to treat. See Fact Sheet 500 for more information on opportunistic infections.
HIV is treated with antiretrovirals (ARVs). The treatment fights the HIV infection and slows down the spread of the virus in the body. Generally, people living with HIV take a combination of medications called HAART (highly active antiretroviral therapy) or cART (combination antiretroviral therapy).
HIV can be transmitted from mother to child during pregnancy, during delivery, or through breast milk, resulting in the baby also contracting HIV. This is the third most common way in which HIV is transmitted globally. In the absence of treatment, the risk of transmission before or during birth is around 20% and in those who also breastfeed 35%. As of 2008, vertical transmission accounted for about 90% of cases of HIV in children. With appropriate treatment the risk of mother-to-child infection can be reduced to about 1%. Preventive treatment involves the mother taking antiretrovirals during pregnancy and delivery, an elective caesarean section, avoiding breastfeeding, and administering antiretroviral drugs to the newborn. Antiretrovirals when taken by either the mother or the infant decrease the risk of transmission in those who do breastfeed. However, many of these measures are not available in the developing world. If blood contaminates food during pre-chewing it may pose a risk of transmission.
Though there are two cases of people who have been cured, there is currently no safe cure for HIV (see fact sheet 485.) There is no way to “clear” HIV from the body. Antiretroviral therapy (ART, see fact sheet 403) can prevent or reverse the damage to your immune system. Most people stay healthy if they stay adherent to ART.
HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get other infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last stage of HIV infection.

Most of the fear surrounding AIDS has to do with its most common form of transmission: sexual behavior. The virus can be passed through any behavior that involves the exchange of blood, semen, or vaginal secretions. Anal intercourse is the highest-risk activity, but oral or vaginal intercourse is dangerous too. Thus, federal health authorities recommend using a condom—yet they caution that condoms are not 100 percent effective; condoms can leak, and they can break. Highly accurate HIV testing is widely available, and often advisable, since infected people can feel perfectly healthy. Although the virus can be contracted immediately upon exposure to it, symptoms of full-blown AIDS may take up to ten years to appear.
The virions of an HIV-1 consist of an envelope, a nucleocapsid, a nucleoid, and a matrix protein. The virus capsid is enveloped. The virions are spherical to pleomorphic and measure 80-100 nm in diameter. The surface projections are small, at 8 nm in length, but densely dispersed and there are inconspicuous spikes that cover the surface evenly. The nucleoid is concentric while the core is rod-shaped or truncated cone-shaped. (source: ICTV db Descriptions)

According to the August 2008 report issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS), as of 2007, approximately 33 million people worldwide are HIV positive. Over half of the 33 million are women and this statistic has remained stable for several years. The highest number of cases is found in sub-Saharan Africa and Southeast Asia.
HIV is a chronic medical condition that can be treated, but not yet cured. There are effective means of preventing complications and delaying, but not preventing, progression to AIDS. At the present time, not all persons infected with HIV have progressed to AIDS, but time has shown that the vast majority do.

For the next two months, Sturdevant and Dot kept a close eye on the young man, scolding, nagging and pleading with him to stay in treatment and to tell his family the truth so he would have someone to support him. On a Friday in March 2016, Sturdevant arranged to visit him and take medication to his house. But when he arrived, there was no answer. “I banged on the door, and then constantly called him all weekend,” Sturdevant said. “On Monday, they told me he had passed away.”
As the sole viral protein on the surface of the virus, the Envelope protein is a major target for HIV vaccine efforts. Over half of the mass of the trimeric envelope spike is N-linked glycans. The density is high as the glycans shield the underlying viral protein from neutralisation by antibodies. This is one of the most densely glycosylated molecules known and the density is sufficiently high to prevent the normal maturation process of glycans during biogenesis in the endoplasmic and Golgi apparatus. The majority of the glycans are therefore stalled as immature ‘high-mannose’ glycans not normally present on human glycoproteins that are secreted or present on a cell surface. The unusual processing and high density means that almost all broadly neutralising antibodies that have so far been identified (from a subset of patients that have been infected for many months to years) bind to or, are adapted to cope with, these envelope glycans.

HIV infection occurs when particular body fluids (blood, semen, vaginal fluid and breast milk) containing the virus come into contact with another person’s tissues beneath the skin (for example, though needle puncture or broken skin), or mucous membranes (the thin moist lining of many parts of the body such as the nose, mouth, throat and genitals).

Condoms made of latex provide good protection against HIV (as well as other common sexually transmitted diseases), but they are not foolproof. Oil-based lubricants (such as petroleum jelly) should not be used because they may dissolve latex, reducing the condom’s effectiveness.
AIDS is a disease that can damage any of the body’s major organ systems because HIV destroys immune system cells. HIV attacks the body through three disease processes: immunodeficiency, autoimmunity, and nervous system dysfunction.

Behavioural changes among injectors and the prompt introduction of harm reduction measures such as needle exchange programmes from the mid-1980s probably prevented many other urban areas in the UK from experiencing the localised epidemics on the scale seen in Scotland. In the UK, sharing rates remain higher than in the mid-1990s with almost one in three injectors in the Unlinked Anonymous survey of injecting drug users reporting direct sharing of needles and syringes in the previous four weeks. The continuing transmission of hepatitis B and hepatitis C in those aged under 25 shows the potential for further HIV spread among injecting drug users.

And having herpes can also be a risk factor for contracting HIV. This is because genital herpes can cause ulcers that make it easier for HIV to enter the body during sex. And people who have HIV tend to have more severe herpes outbreaks more often because HIV weakens the immune system.

If you believe you have been exposed to HIV, seek medical attention IMMEDIATELY. There is some evidence that an immediate course of anti-viral drugs can reduce the chances that you will be infected. This is called post-exposure prophylaxis (PEP), and it has been used to treat health care workers injured by needlesticks for years.

HIV testing is available through any health-care provider, as well as anonymously and confidentially. Home tests for HIV are available for purchase in most pharmacies and online. The U.S. Centers for Disease Control and Prevention (CDC) offers a tool to help the public find their nearest HIV testing site by zip code at https://gettested.cdc.gov. You can also text your ZIP code to KNOW IT (566948), or call 1-800-CDC-INFO (1-800-232-4636). Knowing one’s status is the first step to avoiding AIDS.
