AIDS was first recognized by the U.S. Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade. [21] Between the first time AIDS was readily identified through 2024, the disease is estimated to have caused at least 42.3 million deaths worldwide. [5]
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]
Another cause is the breakdown of the immune surveillance system of the mucosal barrier caused by the depletion of mucosal CD4 + T cells during the acute phase of disease. [ 7 ] This results in the systemic exposure of the immune system to microbial components of the gut’s normal flora, which in a healthy person is kept in check by the ...
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.

[ 131 ] [ 132 ] The belief that HIV was created by the US government as a bioweapon , an idea invented by a Soviet propaganda operation , [ 133 ] [ 134 ] is held by a ...
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.
HIV/AIDS affects economic growth by reducing the availability of human capital. [1] Without proper prevention, nutrition, health care and medicine that is available in developing countries, large numbers of people are developing AIDS. People living with HIV/AIDS will not only be unable to work, but will also require significant medical care.
Although AIDS is a global disease, the CDC reports that Sub-Saharan Africa has the highest prevalence of HIV and AIDS worldwide, and accounts for approximately 61% of all new HIV infections. Other regions significantly affected by HIV and AIDS include Asia and the Pacific, Latin America and the Caribbean, Eastern Europe, and Central Asia. [28]
