In the U.S., more than 1 million people are currently infected with HIV, and approximately 50,000 are newly infected each year. Over the years, more than 600,000 people in the U.S. have died from AIDS, many of them during what should have been their most productive years of life.

People who have been exposed to HIV from a blood splash, needlestick, or sexual contact may reduce the chance of infection by taking antiretroviral drugs for 4 weeks. These drugs are more effective when they are started as soon as possible after the exposure. Taking three or more drugs is currently recommended.

The history of the HIV and AIDS epidemic began in illness, fear and death as the world faced a new and unknown virus. However, scientific advances, such as the development of antiretroviral drugs, have enabled people with access to treatment to live long and healthy lives with HIV.

From a legal, ethical, and moral standpoint, they should warn any prospective sexual partner of their HIV positive status. They should not exchange body fluids during sexual activity and must use whatever preventative measures (such as a latex condom) will afford the partner the most protection.

After many years of research, an untested HIV vaccine has been created.[113] Bi-specific antibodies, that target both the surface of T-cells and viral epitopes, can prevent entry of the virus into human cells.[114] Another group has utilised the same technology to develop a bi-specific antibody that neutralises viral particles by cross-linking of envelope glycoproteins.[115]

simian immunodeficiency virus (SIV) a lentivirus closely related to human immunodeficiency virus that causes inapparent infection in African green monkeys and a disease resembling acquired immunodeficiency syndrome in macaques and chimpanzees.

Cervical cancer is cancer of the entrance to the womb (uterus). Regular pelvic exams and Pap testing can detect precancerous changes in the cervix. Precancerous changes in the cervix may be treated with cryosurgery, cauterization, or laser surgery. The most common symptom of cancer of the cervix is abnormal bleeding.

The objectives of this chapter are to review the epidemiology, pathophysiology, evaluation, and management of HIV/AIDS in youth who acquire the infection perinatally or behaviorally. Although many clinicians who care for adolescents will refer HIV-infected patients, all should be knowledgeable about preventive counseling, postexposure prophylaxis, HIV screening, the acute seroconversion syndrome, and when to begin therapy.

(Acquired Immune Deficiency Syndrome) An immunological disorder in which the body’s immune response system becomes defective, leaving the sufferer open to opportunistic infections and some forms of cancer, such as Kaposi’s sarcoma. It is caused by infection with the HIV virus, transmitted mainly through sexual intercourse or infected blood products.

When HIV infection is diagnosed in a routine test, as for blood donation, in pregnancy, or after counselling a person with a lifestyle that puts him or her at risk, there is not usually full AIDS but just infection with HIV. When the disease is suspected, HIV counselling must precede testing. There is a characteristic presentation of the infection that is described in the separate article Primary HIV Infection. Once the diagnosis is made, the separate article Managing HIV-positive Individuals in Primary Care becomes relevant. The separate article HIV and Skin Disorders outlines the many dermatological manifestations of the disease.

The size of the proviral reservoir correlates to the steady-state viral load and is inversely correlated to the anti-HIV CD8+ T-cell responses. Aggressive early treatment of acute infection may lower the proviral load, but generally, treatment in newly infected (but postseroconversion) patients yields no long-term benefit.
