Expository Essay On HIV/Aids 450 Words

Our body has a protection system called the immune system. The immune system helps protect us from diseases by fighting off germs. But HIV weakens the immune system making a person prone to other diseases.


What is HIV?

HIV stands for Human Immunodeficiency Virus. HIV destroys CD4 called white blood cells which helps the immune system fight diseases. When HIV destroys too many of these cells, the body can’t fight off diseases and infections. This leads to AIDS.

HIV spreads from one person to another through certain body fluids like blood, semen, and vaginal fluids. When these fluids from a person with HIV enter the body of another person, then the HIV can infect that person. This can happen in three main ways.

1. Unprotected sex. This includes anal and vaginal sex without condoms.

2. Sharing of needles and syringes used for injecting drugs or other substances.

3. From an HIV-positive mother to her baby during pregnancy, birth or through breastfeeding.

You cannot get HIV from everyday activities like hugging, holding hands, sharing food or drink, mosquito bites, or toilet seats. Some people think you can get HIV from these things but this is not true.

Symptoms of HIV:

Some people have a flu-like illness within a month or two after getting HIV. But many people don’t notice any symptoms for 10 years or more.

  • Weight loss
  •  Fever
  •  Fatigue
  •  Night sweats
  •  Diarrhea
  •  Swelling of lymph nodes
  • Red or purple blotches on or under the skin.
