No effective cure currently exists for HIV. But with proper medical care, HIV can be controlled. Treatment for HIV is called antiretroviral therapy or ART. If taken the right way, every day, ART can dramatically prolong the lives of many people infected with HIV, keep them healthy, and greatly lower their chance of infecting others. Before the introduction of ART in the mid-1990s, people with HIV could progress to AIDS (the last stage of HIV infection) in a few years. Today, someone diagnosed with HIV and treated before the disease is far advanced can live nearly as long as someone who does not have HIV.

HIV-1 originated in Central Africa during the first half of the 20th century when a closely related chimpanzee virus first infected people. The global spread of HIV-1 began in the late 1970s, and AIDS was first recognized in 1981. In 2015, about 36.7 million people were living with HIV infection worldwide, there were 1.1 million AIDS-related deaths, and 2.1 million people were newly infected.

Animal models show that Langerhans cells are the first cellular targets of HIV, which fuse with CD4+ lymphocytes and spread into deeper tissues. In humans, rapid occurrence of plasma viremia with widespread dissemination of the virus is observed 4-11 days after mucosal entrance of the virus.

It is important to remember that sometimes, for reasons not entirely understood, the viral load can briefly increase. Unexpected increases, therefore, necessitate repeated testing of the viral load before any clinical decisions are made. If, however, the viral load is continually detected despite proper adherence to the prescribed therapy, serious consideration must be given to the possibility that the virus has become resistant to one or more of the medications being given, especially if viral load is greater than 200 copies/mL. There is now an abundance of data showing that the use of drug-resistance tests can improve the response to follow-up regimen. Testing can be used to determine if an individual’s HIV has become resistant to one or more of the drugs that are being taken. There are currently two main types of resistance tests available in the clinic: one that is called a genotype and the other a phenotype assay. The former looks for mutations in the virus and the latter the actual amount of drug it takes to block infection by the patient’s virus. The genotype test is very helpful in those being screened for the presence of resistant virus prior to initiating treatment and those experiencing viral rebound on one of their first treatment regimens. The phenotype test is particularly useful in those who are highly treatment experienced and have substantial amounts of drug resistance, especially to the protease class. The information derived from these tests, along with a tropism test will ultimately tell the provider which of the many approved drugs are likely to be fully active against the specific patient’s virus. Using this information, the goal is to include at least two and at times preferably three fully active drugs in the next regimen in order to optimize the chances of suppressing the viral load to undetectable levels. It is often useful to seek expert consultation in managing those with multidrug resistant virus.

Supporters of a comprehensive approach say AIDS demands frankness. Originating in comprehensive sex ed. theory, their ideas also came from pacesetting health authorities such as former surgeon general c. everett koop. Arguing in the mid-1980s that AIDS classes should be specific and detailed and taught as early as kindergarten, Koop countered conservative arguments by saying, “Those who say ‘I don’t want my child sexually educated’ are hiding their heads in the sand.” This position holds that educators are obligated to teach kids everything that can stop the spread of the disease. “What is the moral responsibility?” Jerald Newberry, a health coordinator of Virginia schools, asked the Washington Times in 1992. “I think it’s gigantic.” Abstinence is a part of this approach, but expecting teens to refrain from having sex was considered by many to be unrealistic given some studies that show that nearly three out of four high school students have had sex before graduation. Thus, the comprehensive curriculum might well include explaining the proper use of condoms, discussing homosexual practices, describing the sterilization of drug needles, and so on.

In adults and adolescents, HIV is most commonly spread by sexual contact with an infected partner. Before routine screening of blood products began in 1985, a small group of children were infected with the virus by contaminated blood products. Currently, nearly all HIV infections in children under the age of 13 are from vertical transmission, which means the virus is passed to the child when they are in their mother’s womb or as they pass through the birth canal. The virus has also been detected in breast milk, and can be spread by breastfeeding.

The RNA genome consists of at least seven structural landmarks (LTR, TAR, RRE, PE, SLIP, CRS, and INS), and nine genes (gag, pol, and env, tat, rev, nef, vif, vpr, vpu, and sometimes a tenth tev, which is a fusion of tat, env and rev), encoding 19 proteins. Three of these genes, gag, pol, and env, contain information needed to make the structural proteins for new virus particles.[21] For example, env codes for a protein called gp160 that is cut in two by a cellular protease to form gp120 and gp41. The six remaining genes, tat, rev, nef, vif, vpr, and vpu (or vpx in the case of HIV-2), are regulatory genes for proteins that control the ability of HIV to infect cells, produce new copies of virus (replicate), or cause disease.[21]

* Data include all participants with complete valid survey data who tested negative during NHBS and cycle-specific inclusion criteria: men who have sex with men (born male, identified as male, and had oral or anal sex with another man); persons who inject drugs (injected drugs in the past 12 months); heterosexual persons at increased risk (male or female [not transgender], had sex with a member of the opposite sex in the past 12 months, never injected drugs, and met low income [not exceeding U.S. Department of Health and Human Services poverty guidelines] or low education [high school education or less] criteria). Groups are mutually exclusive.

The best time to start drug treatment is as soon as possible, even if people are not sick and their CD4 count is still above 500 (normal is 500 to 1,000). Doctors used to wait until the CD4 count was below 500 to start drug treatment. However, research has shown that people who are promptly treated with antiretroviral drugs are less likely to develop AIDS-related complications and to die of them.

Preexposure prophylaxis with antiretrovirals (PrEP): In PrEP, people who are not infected with HIV but are at high risk (eg, by having an HIV-infected sexual partner) take an antiretroviral drug daily to reduce their risk of infection. The combination of tenofovir disoproxil fumarate plus emtricitabine (TDF/FTC) can be used. Use of PrEP does not eliminate the need to use other methods of reducing risk of HIV infection, including using condoms and avoiding high-risk behaviors (eg, needle sharing). Data concerning infants of HIV-negative mothers taking TDF/FTC PrEP during pregnancy are incomplete, but currently, no adverse effects have been reported in children born to HIV-infected women treated with TDF/FTC. Use of PrEP to reduce the risk of HIV infection in injection drug users is being studied. For the current CDC recommendations, see Pre-Exposure Prophylaxis (PrEP).
