Correct option is A
AIDS stands for Acquired Immune Deficiency Syndrome, a disease caused by the Human Immunodeficiency Virus (HIV). HIV weakens a person’s immune system by destroying important cells that fight disease and infection. The term “acquired” refers to the fact that the disease is contracted rather than inherited. “Immune deficiency” indicates a weakening of the immune system, and “syndrome” refers to a collection of symptoms and infections associated with the disease.
Important Key Points:
- AIDS is the final stage of HIV infection, characterized by a severely compromised immune system.
- The virus specifically targets CD4 cells, also known as T-helper cells.
- AIDS can lead to various opportunistic infections and cancers, which the body would typically be able to fight off.
- HIV is spread through contact with certain body fluids such as blood, semen, vaginal fluids, and breast milk.
- Effective antiretroviral therapy (ART) can control the virus, allowing individuals to live longer, healthier lives.
- HIV transmission can be prevented through safe practices such as the use of condoms and pre-exposure prophylaxis (PrEP).
