These symptoms can be so mild that you might not even notice them. However, the amount of virus in your bloodstream (viral load) is quite high at this time. As a result, the infection spreads more easily during primary infection than during the next stage.

The AIDS Taskforce of Greater Cleveland provides a compassionate and collaborative response to the needs of people infected, affected and at risk of HIV/AIDS. This is accomplished through leadership in prevention, education, supportive services and advocacy.
The stage of symptomatic infection, in which the body’s immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia).
HIV infection can cause AIDS to develop. However, it is possible to contract HIV without developing AIDS. Without treatment, HIV can progress and, eventually, it will develop into AIDS in the vast majority of cases.
When HIV becomes resistant to HAART, salvage therapy is required to try to suppress the resistant strain of HIV. Different combinations of medications are tried to attempt to reduce viral load. This is often not successful, unfortunately, and the patient will usually develop AIDS and its complications.
Ultimately, HIV causes AIDS by depleting CD4+ T cells. This weakens the immune system and allows opportunistic infections. T cells are essential to the immune response and without them, the body cannot fight infections or kill cancerous cells. The mechanism of CD4+ T cell depletion differs in the acute and chronic phases. During the acute phase, HIV-induced cell lysis and killing of infected cells by cytotoxic T cells accounts for CD4+ T cell depletion, although apoptosis may also be a factor. During the chronic phase, the consequences of generalized immune activation coupled with the gradual loss of the ability of the immune system to generate new T cells appear to account for the slow decline in CD4+ T cell numbers.
Morquio’s syndrome; type IV mucopolysaccharoidosis severe skeletal dysplasia including spine/thorax deformity, irregular epiphyses but normal shaft length of long bones, enlarged joints, flaccid ligaments, waddling gait and urinary abnormalities, due to autosomal-recessive error of mucopolysaccharide metabolism
The human immunodeficiency virus (HIV) was identified in 1983, 2 years after the first five cases of the acquired immunodeficiency syndrome (AIDS) were reported by the Centers for Disease Control and Prevention (CDC). The ensuing years witnessed rapid advances in the prevention and management of HIV/AIDS and dramatic shifts in its epidemiology. In developed countries, the availability of effective antiretroviral therapy reduced perinatal transmission to 1–3%; prolonged survival; increased resistance to 15% of circulating strains; and introduced a set of common side effects called body-fat abnormalities. In developing countries, however, less than 20% of those needing antiretroviral therapy receive it and interventions to reduce behavioral risk have had limited impact. As a result, the developing world accounts for 95% of AIDS-related deaths and new HIV infections.

HIV disease becomes AIDS your immune system is seriously damaged. If you have less than 200 CD4 cells or if your CD4 percentage is less than 14%, you have AIDS. See Fact Sheet 124 for more information on CD4 cells. If you get an opportunistic infection, you have AIDS. There is an “official” list of these opportunistic infections put out by the Centers for Disease Control (CDC). The most common ones are:
The main treatment for HIV is antiretroviral therapy (ART), a combination of daily medications that stop the virus from reproducing. This helps protect your CD4 cells, keeping your immune system strong enough to fight off disease.

Two RNA genomes are encapsidated in each HIV-1 particle (see Structure and genome of HIV). Upon infection and replication catalyzed by reverse transcriptase, recombination between the two genomes can occur. Recombination occurs as the single-strand (+)RNA genomes are reverse transcribed to form DNA. During reverse transcription, the nascent DNA can switch multiple times between the two copies of the viral RNA. This form of recombination is known as copy-choice. Recombination events may occur throughout the genome. Anywhere from two to 20 recombination events per genome may occur at each replication cycle, and these events can rapidly shuffle the genetic information that is transmitted from parental to progeny genomes.
During the first few months of infection, an HIV test may provide a false-negative result. This is because it takes time for the immune system to build up enough antibodies to be detected in a blood test. But the virus is active and highly contagious during this time.
During successful treatment, the viral load decreases to very low or undetectable levels (less than about 20 to 40 copies per microliter of blood). However, inactive (latent) HIV is still present within cells, and if treatment is stopped, HIV starts replicating and the viral load increases.
In 2006, male circumcision was found to reduce the risk of female-to-male HIV transmission by 60%.81 Since then, the WHO and UNAIDS have emphasised that male circumcision should be considered in areas with high HIV and low male circumcision prevalence.82
Isolates of HIV-1 and HIV-2 with resistance to antiretroviral drugs arise through natural selection and genetic mutations, which have been tracked and analyzed. The Stanford HIV Drug Resistance Database and the International AIDS Society publish lists of the most important of these; first year listing 80 common mutations, and the latest year 93 common mutations, and made available through the Stanford HIV RT and Protease Sequence Database.
Behind Grace House is a small, quiet makeshift graveyard that holds the cremated remains of 35 or so residents whose families did not pick up their bodies after they died. Ceramic angels, pieces of glasswork and other mementos left by friends in memory of the deceased dot the patch of earth at the base of a pecan tree. Stacey Howard, 47, the director of programs, remembers one of the last people buried there, a young man who was H.I.V.-positive and addicted to crack, who had lived off and on at Grace House before he was found dead on the street in the spring of 2016.
