Awareness of modes of transmission is very important, as the key to tackling this disease lies less in treating it than in preventing its spread. The relative importance of the various means of transmission varies considerably from country to country and even within countries. The following is derived from UK sources.

HIV is spread primarily by unprotected sex (including anal and oral sex), contaminated blood transfusions, hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding.[12] Some bodily fluids, such as saliva and tears, do not transmit HIV.[13] Methods of prevention include safe sex, needle exchange programs, treating those who are infected, and male circumcision.[5] Disease in a baby can often be prevented by giving both the mother and child antiretroviral medication.[5] There is no cure or vaccine; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy.[6][7] Treatment is recommended as soon as the diagnosis is made.[14] Without treatment, the average survival time after infection is 11 years.[15]

The viral load actually measures the amount of virus in the blood and may partially predict whether or not the CD4 cells will decline in the coming months. In other words, those people with high viral loads are more likely to experience a decline in CD4 cells and progression of disease than those with lower viral loads. In addition, the viral load is a vital tool for monitoring the effectiveness of new therapies and determining when drugs are and are not working. Thus, the viral load will decrease within weeks of initiating an effective antiviral regimen. If a combination of drugs is very potent, the number of HIV copies in the blood will decrease by as much as hundredfold, such as from 100,000 to 1,000 copies per mL of blood in the first two weeks and gradually decrease even further during the ensuing 12-24 weeks. The ultimate goal is to get viral loads to below the limits of detection by standard assays, usually less than 20 to 50 copies per mL of blood. When viral loads are reduced to these low levels, it is believed that the viral suppression will persist for many years as long as the patient consistently takes their medications.

Counseling for pregnant women:Mother-to-child transmission has been virtually eliminated by HIV testing, treatment with ART, and, in developed countries, use of breast milk substitutes. If pregnant women test positive for HIV, risk of mother-to-child transmission should be explained. Pregnant women who do not accept immediate treatment for their HIV infection should be encouraged to accept therapy to protect the unborn baby, typically beginning at about 14 wk gestation. Combination therapy is typically used because it is more effective than monotherapy and less likely to result in drug resistance. Some drugs can be toxic to the fetus or woman and should be avoided. If women meet criteria for ART, they should begin a regimen tailored to their history and stage of pregnancy and continue it throughout pregnancy. Cesarean delivery can also reduce risk of transmission. Regardless of the antepartum regimen used or mode of delivery, all HIV-infected women should be given IV zidovudine during labor, and after birth, neonates should be given oral zidovudine, which is continued for 6 wk after delivery (see also Prevention of Perinatal Transmission). Some women choose to terminate their pregnancy because HIV can be transmitted in utero to the fetus or for other reasons.

Side effects associated with EFV are mostly dizziness, confusion, fatigue, and vivid dreams. These tend to be most prominent during the first weeks of therapy and then often decrease in severity. It is generally recommended that EFV be taken at bedtime so that the patient is asleep during the time dizziness and confusion may be most severe. It is also noteworthy that there may be an increased risk of depression associated with the use of this drug, and it should be used with caution in those with poorly managed depression. Rash and liver inflammation can occur with both EFV and DLV, and these drugs may also be linked to abnormalities of lipids in the blood.

A count below about 50 cells per microliter of blood is particularly dangerous because additional opportunistic infections that can rapidly cause severe weight loss, blindness, or death commonly occur. These infections include

One way to measure the damage to your immune system is to count your CD4 cells you have. These cells, also called “T-helper” cells, are an important part of immune system. Healthy people have between 500 and 1,500 CD4 cells in a milliliter of blood. Fact Sheet 124 has has more information on CD4 cells.

Antibody tests in children younger than 18 months are typically inaccurate due to the continued presence of maternal antibodies.[106] Thus HIV infection can only be diagnosed by PCR testing for HIV RNA or DNA, or via testing for the p24 antigen.[26] Much of the world lacks access to reliable PCR testing and many places simply wait until either symptoms develop or the child is old enough for accurate antibody testing.[106] In sub-Saharan Africa as of 2007–2009 between 30 and 70% of the population were aware of their HIV status.[107] In 2009, between 3.6 and 42% of men and women in Sub-Saharan countries were tested[107] which represented a significant increase compared to previous years.[107]

HIV progressively destroys some types of white blood cells called CD4+ lymphocytes. Lymphocytes help defend the body against foreign cells, infectious organisms, and cancer. Thus, when HIV destroys CD4+ lymphocytes, people become susceptible to attack by many other infectious organisms. Many of the complications of HIV infection, including death, usually result from these other infections and not from HIV infection directly.

Needles. HIV is frequently spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa, through accidental sticks with contaminated needles or other medical instruments, is rare.

Stevens-Johnson syndrome (SJS) is a rare allergic reaction to HIV medication. Symptoms include fever and swelling of the face and tongue. Rash, which can involve the skin and mucous membranes, appears and spreads quickly.

According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection diagnoses in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015. [72] In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infection diagnoses decreased 9%.

AIDS begins with HIV infection. People infected with HIV may have no symptoms for ten years or longer, but they can still transmit the infection to others during this symptom-free period. Meanwhile, their immune system gradually weakens until they develop AIDS.

He said he revealed the diagnosis to people he thought he trusted, but some of them demanded money to keep the information to themselves. He paid those people “in the millions,” he said. Later in the show, Lauer said that Sheen told him it was more than $10 million.

Treatments with HAART have shown considerable progress since the first antiretroviral was approved for use by the FDA in 1987. Impressive improvements in life expectancy and quality of life have ensued. There are, however, still many problems. Although HAART is able to suppress the viral load in the plasma, it fails to eradicate it,and once HAART is initiated, treatment needs to be continued for life. The side-effects of long-term HAART include lipodystrophy, lactic acidosis, insulin resistance, and hyperlipidaemia.

In contrast, when these strains infect species that have not adapted to SIV (“heterologous” or similar hosts such as rhesus or cynomologus macaques), the animals develop AIDS and the virus generates genetic diversity similar to what is seen in human HIV infection.[94] Chimpanzee SIV (SIVcpz), the closest genetic relative of HIV-1, is associated with increased mortality and AIDS-like symptoms in its natural host.[95] SIVcpz appears to have been transmitted relatively recently to chimpanzee and human populations, so their hosts have not yet adapted to the virus.[90] This virus has also lost a function of the Nef gene that is present in most SIVs. For non-pathogenic SIV variants, Nef suppresses T cell activation through the CD3 marker. Nef’s function in non-pathogenic forms of SIV is to downregulate expression of inflammatory cytokines, MHC-1, and signals that affect T cell trafficking. In HIV-1 and SIVcpz, Nef does not inhibit T-cell activation and it has lost this function. Without this function, T cell depletion is more likely, leading to immunodeficiency.[95][96]

History marks the beginning of the American AIDS epidemic as June 5, 1981, when an issue of the C.D.C.’s Morbidity and Mortality Weekly Report — the authoritative voice of the agency — highlighted five cases of pneumocystis pneumonia (PCP) in previously healthy men in Los Angeles. Healthy people do not contract a disease like PCP, which had been largely confined until then to patients on medication to suppress their immune systems for an organ transplant or cancer patients on chemotherapy. Though not stated explicitly, the language of the report, by omitting race, implied that its “five young men, all active homosexuals,” were white, which they were. But there were two more documented cases, not mentioned in the notice, and these sixth and seventh cases were black — one of them a gay African-American, the other a heterosexual Haitian.

Human immunodeficiency virus (HIV) is the virus that causes acquired immune deficiency syndrome (AIDS). HIV destroys the body’s immune system and eventually leads to AIDS. People with AIDS develop many diseases and “opportunistic” infections (such as pneumonia, tuberculosis, cancer, and skin infections) that may ultimately lead to death. Prevention is critical. There is no cure for HIV/AIDS, but currently, there are effective treatments that can drastically slow the disease process. If you have been exposed to the HIV virus in any number of ways, you can very easily be tested to determine whether or not you have been infected with the virus.
