The symptoms of AIDS are primarily the result of conditions that do not normally develop in individuals with healthy immune systems. Most of these conditions are opportunistic infections caused by bacteria, viruses, fungi, and parasites that are normally controlled by the elements of the immune system that HIV damages. [11]
HIV/AIDS research includes all medical research which attempts to prevent, treat, or cure HIV/AIDS, along with fundamental research about the nature of HIV as an infectious agent, and about AIDS as the disease caused by HIV. Many governments and research institutions participate in HIV/AIDS research.
Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. [3] Without treatment, the average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. [4]

WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease.
Most proteins known to be involved in hereditary AIDs are involved in the regulation of interleukin-1 β (IL-1β). Their mutations induce increased and/or prolonged secretion of IL-1β, a pro-inflammatory and pyrogenic cytokine. [4] Patients with AIDs often suffer from non-infectious fever and systemic and/or disease-specific organ inflammation.
In the discussion of cancers (a non-infectious disease), the term "latency period" is used to indicate the time that passes between being exposed to something that can cause disease (such as radiation or a virus) and having symptoms. [10] Doctors and medical journals may speak of "latent" tumors, which are present but not active or causing ...
The AIDS epidemic, caused by HIV (Human Immunodeficiency Virus), found its way to the United States between the 1970s and 1980s, [2] but was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in homosexual men in Los Angeles, New York City, and San Francisco in 1981.
