HIV stands for human immunodeficiency virus. It harms your immune system by destroying the white blood cells that fight infection. This puts you at risk for serious infections and certain cancers. AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV. Not everyone with HIV develops AIDS.
Blood transmission — the risk of transmitting HIV through blood transfusion is extremely low in developed countries, thanks to meticulous screening and precautions. However, among people who inject drugs, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.

After an hour they folded up the table and stuffed the condoms and brochures back into a gym bag, dropped it next to Sturdevant, who was sipping a syrupy cocktail from a can, and headed out to the dance floor. A remix of Rihanna’s “Where Have You Been” came on, so loud the walls shook. Like everyone else, Stevenson and Watson, who are dance coaches and choreographers, had perfected their moves from watching YouTube videos of the Prancing J-Settes. Stevenson bent and thrust, at once explosive, angular and precise. Watson’s face was still as a stone; as he snapped his to the side, his waist-length dreadlocks whipped around his head. After a few songs, the music ended as the club prepared for a 1 a.m. drag show. Stevenson, sweaty and breathless, melted into a conversation with other dancers.
Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.
The basis of management is described in the separate article Human Immunideficiency Virus (HIV). There may be defining conditions such as Pneumocystis jirovecii pneumonia that will need treatment. Highly active antiretroviral therapy (HAART) has improved the prognosis enormously in terms of duration of survival but premature death is to be expected.
HIV-1 has 6 additional accessory genes: tat, rev, nef, vif, vpu, and vpr. HIV-2 does not have vpu but instead has the unique gene vpx. The only other virus known to contain the vpu gene is simian immunodeficiency virus in chimpanzees (SIVcpz), which is the simian equivalent of HIV.  Interestingly, chimpanzees with active HIV-1 infection are resistant to disease. 
A poor CD4 count response is more likely if the CD4 count at initiation of treatment is low (especially if < 50/μL) and/or the HIV RNA level is high. However, marked improvement is likely even in patients with advanced immunosuppression. An increased CD4 count correlates with markedly decreased risk of opportunistic infections, other complications, and death. With immune restoration, patients, even those with complications that have no specific treatment (eg, HIV-induced cognitive dysfunction) or that were previously considered untreatable (eg, progressive multifocal leukoencephalopathy), may improve. Outcomes are also improved for patients with cancers (eg, lymphoma, Kaposi sarcoma) and most opportunistic infections. HIV-1 and HIV-2 are retroviruses in the Retroviridae family, Lentivirus genus. They are enveloped, diploid, single-stranded, positive-sense RNA viruses with a DNA intermediate, which is an integrated viral genome (a provirus) that persists within the host-cell DNA. The opinions expressed in this article are those of the authors and do not necessarily reflect those of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Institutes of Health, the Department of Health and Human Services, or the U.S. Government. Two points in this update deserve emphasis. First, the eventual case-mortality rate of AIDS, a few years after diagnosis, may be far greater than the 41% overall case-mortality rate noted above. Second, the reported incidence of AIDS has continued to increase rapidly. Only a small percentage of cases have none of the identified risk factors (male homosexuality, intravenous drug abuse, Haitian origin, and perhaps hemophilia A). To avoid a reporting bias, physicians should report cases regardless of the absence of these factors. HIV continues to be a major public health crisis both in the United States and around the world. While major scientific advances have made it easier than ever to prevent and treat HIV, there remains no vaccine or cure, and tens of thousands of people continue to contract HIV every year. Insufficient funding for public health programs, ideological opposition to common sense prevention policies, and societal barriers like stigma and discrimination, have made it especially difficult for us to turn the tide against the epidemic. Together, HRC and the HRC Foundation are committed to working with our friends, partners, members, and supporters to end the dual epidemics of HIV and HIV-related stigma. 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. 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. One of the obstacles to treatment of the human immunodeficiency virus is its high genetic variability. HIV can be divided into two major types, HIV type 1 (HIV-1) and HIV type 2 (HIV-2). HIV-1 is related to viruses found in chimpanzees and gorillas living in western Africa, while HIV-2 viruses are related to viruses found in the endangered west African primate sooty mangabey. HIV-1 viruses may be further divided into groups. The HIV-1 group M viruses predominate and are responsible for the AIDS pandemic. Group M can be further subdivided into subtypes based on genetic sequence data. Some of the subtypes are known to be more virulent or are resistant to different medications. Likewise, HIV-2 viruses are thought to be less virulent and transmissible than HIV-1 M group viruses, although HIV-2 is known to cause AIDS. Near the end of life, many people have pain and other distressing symptoms (such as agitation) and usually lose their appetite. Hospice programs are particularly equipped to deal with such problems. They can provide comprehensive support and care, which focuses on managing symptoms, helping dying people maintain their independence, and supporting their caregivers. Human immunodeficiency virus infection and AIDs can cause a plethora of hematologic problems. Early on during HIV infection, immune thrombocytopenia is common as is the development of antiphospholipid antibodies. Anemia is the most common manifestation of HIV infection and is multifactorial due to both direct and indirect effects of the virus.12 Anemia is most often a hypoproliferative, low reticulocyte anemia due to anemia of chronic disease. Often, there is a blunted erythropoietin response. Coombs-positive autoimmune hemolytic anemia also occurs with increased frequency in HIV infection. Antiretroviral therapy often causes macrocytosis. In viruses that have membranes, membrane-bound viral proteins are synthesized by the host cell and move, like host cell membrane proteins, to the cell surface. When these proteins assemble to form the capsid, part of the host cell membrane is pinched off to form the envelope of the virion. Because host cells do not have the ability to replicate “viral RNA” but are able to transcribe messenger RNA, RNA viruses must contain enzymes to produce genetic material for new virions. For certain viruses the RNA is replicated by a viral enzyme (transcriptase) contained in the virion, or produced by the host cell using the viral RNA as a messenger. In other viruses a reverse transcriptase contained in the virion transcribes the genetic message on the viral RNA into DNA, which is then replicated by the host cell. Reverse transcriptase is actually a combination of two enzymes: a polymerase that assembles the new DNA copy and an RNase that degrades the source RNA. What is a health screening?
