  2. Pathophysiology of HIV/AIDS - Wikipedia

    en.wikipedia.org/wiki/Pathophysiology_of_HIV/AIDS

    After the virus enters the body there is a period of rapid viral replication, leading to an abundance of virus in the peripheral blood. During primary infection, the level of HIV may reach several million virus particles per milliliter of blood. [2] This response is accompanied by a marked drop in the numbers of circulating CD4 + T cells.

  3. HIV/AIDS - Wikipedia

    en.wikipedia.org/wiki/HIV/AIDS

    HIV-1 is the virus that was originally discovered (and initially referred to also as LAV or HTLV-III). It is more virulent, more infective, [99] and is the cause of the majority of HIV infections globally. The lower infectivity of HIV-2 as compared with HIV-1 implies that fewer people exposed to HIV-2 will be infected per exposure.

    Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower ...

    HIV is a major cause of cardiomyopathy (problems with the heart muscle that reduce the efficiency with which the heart pumps blood). The most common type of HIV induced cardiomyopathy is dilated cardiomyopathy also known as eccentric ventricular hypertrophy which leads to impaired contraction of the ventricles due to volume overload.

  6. Sexually transmitted infection - Wikipedia

    en.wikipedia.org/wiki/Sexually_transmitted_infection

    HIV (human immunodeficiency virus) damages the body's immune system, which interferes with its ability to fight off disease-causing agents. The virus kills CD4 cells, which are white blood cells that help fight off various infections. HIV is carried in body fluids and is spread by sexual activity.

  7. Immune reconstitution inflammatory syndrome - Wikipedia

    en.wikipedia.org/wiki/Immune_reconstitution...

    Immune reconstitution inflammatory syndrome (IRIS) is a condition seen in some cases of HIV/AIDS or immunosuppression, in which the immune system begins to recover, but then responds to a previously acquired opportunistic infection with an overwhelming inflammatory response that paradoxically makes the symptoms of infection worse.

  8. Signs and symptoms of HIV/AIDS - Wikipedia

    en.wikipedia.org/wiki/Signs_and_symptoms_of_HIV/AIDS

    Figure 1. Early Symptoms of HIV. The stages of HIV infection are acute infection (also known as primary infection), latency, and AIDS. Acute infection lasts for several weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores. The latency stage ...

    en.wikipedia.org/wiki/Misconceptions_about_HIV/AIDS

    Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development ...
