Question

Why does a person suffering from AIDS become sick frequently?

Answer 1

AIDS or Acquired Immune Deficiency Syndrome is a disease that is caused due to the infection of HIV and it spreads through contact with infected body fluids such as blood, semen or vaginal discharges. Usually, AIDS is the final stage of HIV infection.

Complete answer:
Acquired Immune Deficiency Syndrome or AIDS, is a condition of disorder that is caused by the infection of the human immunodeficiency virus or HIV. At the initial stage of infection, there are no symptoms noticed in the affected person or may feel a little influenza-like illness for a short period. The infection of HIV is followed by a long period without any symptoms. As the infection progresses in the body, it interacts more with the immune system of the body and increases the risk of developing common infections such as tuberculosis, as well as other viral infections. These late arise symptoms of infection are referred to as acquired immunodeficiency syndrome or AIDS. This stage is related to unintentional weight loss.
The acquired immune deficiency syndrome or AIDS was first observed in the early 1980s which is due to infection of HIV which is a unique human RNA virus. HIV belongs to the group of viruses known as retroviruses. This virus generally infects the cells of the body’s immune system. HIV mainly attacks the T helper cells or CD4 cells, which lead to the ultimate death of the cell. These cells play a vital role in the regulation of immune responses to invading microorganisms. If the HIV-affected person remains untreated, ten to a hundred billion new viruses are formed per day which causes ultimately a progressive loss of CD4 cells for several years to as long as a decade.
HIV is transmitted primarily by unsafe or contaminated blood transfusions, use of hypodermic needles, and it also passes from mother to child during gestation and childbirth.
As the infection of AIDS causes destruction in the body’s immune system or the natural self-defence mechanism of the human body, the affected person gets prone to several other infections. Therefore, a person suffering from AIDS becomes sick frequently.

Note: AIDS is a disease where the immune system of the body is affected. It is caused due to the infection of retrovirus-HIV or human immunodeficiency virus. This virus destroys the human body's immune system or self-defence mechanism. As the immune system of the body, therefore the affected person becomes prone to several other infections. Therefore, a person suffering from AIDS becomes sick frequently.
