Question

Why a person suffering HIV aids dies even due to small infection?

Answer 1

Hint:HIV or Human Immunodeficiency Virus when it invades inside the human body, it weakens the immune system. If a person gets a small infection, in the absence of the body's natural immune system, it can lead to death because of a lack of resistance in the infected person's body as they are not able to fight against infection that leads to the death.

Complete answer:AIDS or Acquired Immune Deficiency Syndrome is the stage in which a person is infected with HIV, which weakens the natural immune system. HIV infected person gets an opportunistic infection which is not eliminated by the body HIV infected individual due to lack of resistance power, that leads to the death of the infected person.
HIV is a sexually transmitted disease that spreads by sexual intercourse or transfer of blood from an infected individual, infected semen, pre-ejaculation fluid and vaginal fluid. HIV is a retrovirus, and its genus is Lentivirus, which possesses two strands of RNA genome that is encapsulated in two protective layers, which are named as inner capsid and outer lipid membrane with glycoprotein complex.
HIV infects the vital cells of the human immune system, like a helper T cell, dendritic cell and macrophages. This leads to the lower the number of CD4+ T cells via several mechanisms, that also include pyroptosis and apoptosis, and leads to a weakened immune system.

Note:HIV has been characterized into two different forms, HIV-1 and HIV-2 and termed as a lymphadenopathy-associated virus (LAV). HIV virus weakens the immune system, and when another infection occurs, the body lacks the ability to fight against another infection, and this can be fatal and leads to the death of the infected individual.
