Some enveloped RNA viruses can be produced in infected cells that continue growing and dividing without being killed. This probably involves some sort of intracellular regulation of viral growth. It is also possible for the DNA of some viruses to be incorporated into the host cell DNA, producing a carrier state. These are almost always retroviruses, which are called proviruses before and after integration of viral DNA into the host genome.
The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which can infect humans when it comes in contact with tissues that line the vagina, anal area, or eyes, or through a break in the skin.

An alternative view holds that unsafe medical practices in Africa after World War II, such as unsterile reuse of single use syringes during mass vaccination, antibiotic and anti-malaria treatment campaigns, were the initial vector that allowed the virus to adapt to humans and spread.
The goal is to start PEP as soon after exposure as possible if prophylaxis is warranted. CDC recommends providing PEP within 24 to 36 h after exposure; a longer interval after exposure requires the advice of an expert.
Integrase strand transfer inhibitors (integrase inhibitors or integrases) stop HIV genes from becoming incorporated into the human cell’s DNA and are very well tolerated. Raltegravir (Isentress) was the first drug in this class. Elvitegravir is part of a fixed-dose combination (elvitegravir/cobicistat/tenofovir/emtricitabine) taken as one pill once daily, called Stribild. Dolutegravir (Tivicay) is also available in a once-daily combination pill with two NRTIs, abacavir and lamivudine, called Triumeq.
Human immunodeficiency virus often is diagnosed in women during prenatal antibody screening or in conjunction with screening for sexually transmitted diseases (STDs). Because many women initially identified as infected with HIV are not aware that they have been exposed to HIV and do not consider themselves to be at risk, universal testing with patient notification is more effective than targeted, risk-based testing in identifying those who are infected with HIV (4). The tension between competing goals for HIV testing—testing broadly in order to treat the maximum number of women infected with HIV and, if pregnant, to protect their newborns, and counseling thoroughly in order to maximally protect a woman’s autonomy and right to participate in decision making—has sparked considerable debate.
Human immunodeficiency virus (HIV) associated cholangiopathy has been described in children.95 As in adults, the biliary abnormalities include irregularities of contour and caliber of the intrahepatic and extrahepatic ducts and papillary stenosis. The changes may result from concomitant infection with opportunistic organisms such as cytomegalovirus and Cryptosporidium parvum.
Clinical findings Weight loss exceeding 10% of body weight, protracted asthenia, continuous fever for >1 month, diarrhoea >1 month, persistent cough, oropharyngeal candidiasis, relapsing cutaneous herpes, generalised pruritic dermatosis, generalised lymphadenopathy, Kaposi’s sarcoma.
Historically, the greatest success in preventing viral transmission has resulted from the development of preventative vaccines. Unfortunately, decades of research to develop an HIV vaccine has led to little hope for success. In 2007, a major setback in this area occurred when the STEP study investigating a promising vaccine candidate was prematurely stopped due to the lack of evidence that it produced any protection from HIV infection. In contrast, a glimmer of hope did emerge with the report in 2009 of the results of the RV 144 Thai HIV vaccine trial, which demonstrated borderline effectiveness in the more than 16,000 recipients. While this vaccine demonstrated only limited evidence of protection, research is under way to further explore what can be learned for future vaccine development from this modest success.
Stage II (also known as clinically asymptomatic stage): This stage may last for 8-10 years with no major symptoms except for swollen glands (lymph nodes), some weight loss, mouth ulceration and mild skin and nail infections.

AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make “antibodies,” special molecules to fight HIV.
Although RTV is approved for treatment of HIV-infected patients at a dose of 600 mg twice daily, it is virtually never used at this dose because of severe side effects. Because of this, it is not included in the above table. However, PIs are frequently dosed with low doses of RTV. RTV delays the clearance of the other drugs from the system, making them easier to take and more effective. The dose of RTV varies depending upon which drugs it is being taken with and how it is being administered. The only PI that is not substantially affected by RTV is NFV. Another recently approved boosting agent is COBI which has no anti-HIV activity but can be given with once daily ATV or DRV as an alternative to RTV for pharmacologic boosting. There are also fixed-dose combinations of each, for example, ATV 300 mg combined with COBI 150 mg (Evotaz) and DRV 800 mg combined with COBI 150 mg (Prezcobix). A single-tablet formulation is in advanced stages of development, DRV/COBI/FTC/TAF (800/150/200/10 mg) once daily.

During the 2004 election, the PBS journalist Gwen Ifill brought the issue to the mainstream stage as the moderator for the vice-presidential debate. She asked the candidates Dick Cheney and John Edwards what they planned to do to end the spread of H.I.V./AIDS — “not about AIDS in China or Africa, but AIDS right here in this country” — among black women. Cheney replied that he was not aware of the numbers, while Edwards spent more than a minute discussing AIDS in Africa. In 2006, I attended the International AIDS Conference in Toronto with a delegation of black journalists, civil rights leaders, government officials, politicians and celebrities, including the singer Sheryl Lee Ralph, Representatives Maxine Waters and Barbara Lee, the Rev. Jesse Jackson and Julian Bond, chairman of the N.A.A.C.P., who famously announced, “Now is the time for us to face the fact that AIDS has become a black disease.”
“If you’re already losing weight, that means the immune system is usually fairly depleted,” Dr. Malvestutto says. “This is the patient who has lost a lot of weight even if they continue to eat as much as possible. This is late presentation. We still see a lot of these.” It has become less common, however, thanks to antiretroviral therapy.
HIV-1 and HIV-2 appear to package their RNA differently. HIV-1 will bind to any appropriate RNA. HIV-2 will preferentially bind to the mRNA that was used to create the Gag protein itself.
When initially infected, many people have no noticeable symptoms, but within 1 to 4 weeks, fever, rashes, sore throat, swollen lymph nodes, fatigue, and a variety of less common symptoms develop in some people. Symptoms of initial (primary) HIV infection last from 3 to 14 days.
The Siliciano laboratory occupies the eighth floor of the Miller Research Building, at the Johns Hopkins School of Medicine. The twenty-six-person research team—technicians, students, fellows, and faculty—works in an airy, open space and in a smaller Biosafety Level 3 facility on the north side of the building. There they handle the specimens of their clinic’s H.I.V.-positive subjects and many more from labs like Deeks’s worldwide. Inside a room with negative air pressure, researchers retrieve blood samples from an incubator and place them in a laminar flow hood, which draws up a stream of air. Nothing leaves the facility without being double-bagged and sterilized.
Antiviral therapy suppresses the replication of the HIV virus in the body. A combination of several antiretroviral agents, termed Highly Active Anti-Retroviral Therapy (HAART), has been highly effective in reducing the number of HIV particles in the blood stream (as measured by a blood test called the viral load). This can help the immune system bounce back for a while and improve T-cell counts.
In the early days, the CDC did not have an official name for the disease, often referring to it by way of the diseases that were associated with it, for example, lymphadenopathy, the disease after which the discoverers of HIV originally named the virus. They also used Kaposi’s sarcoma and opportunistic infections, the name by which a task force had been set up in 1981. At one point, the CDC coined the phrase “the 4H disease”, since the syndrome seemed to affect heroin users, homosexuals, hemophiliacs, and Haitians. In the general press, the term “GRID”, which stood for gay-related immune deficiency, had been coined. However, after determining that AIDS was not isolated to the gay community, it was realized that the term GRID was misleading and the term AIDS was introduced at a meeting in July 1982. By September 1982 the CDC started referring to the disease as AIDS.
Gut-associated lymphoid tissue (GALT) plays a role in HIV replication.  Although the portal of entry for HIV infection is typically through direct blood inoculation or exposure of the virus to genital mucosal surfaces, the GI tract contains a large amount of lymphoid tissue, making this an ideal site for HIV replication.
