Human Immunodeficiency Virus(HIV) – Causes, Symptoms and Treatment


Human immunodeficiency virus, or HIV, is the virus that causes acquired immune deficiency syndrome (AIDS). The virus weakens a person’s ability to fight infections and cancer. People with HIV are said to have AIDS when they develop certain infections or cancers or when their CD4 (T-cell) count is less than 200.


What are the causes of human immunodeficiency virus?

Unlike other diseases whose causes are external lifestyle habits, HIV is caused by simian immunodeficiency virus which is thought to have jumped from chimpanzees to humans decades ago.


Symptoms of human immunodeficiency virus:

The symptoms of HIV include:

  • Diarrhea
  • Fever
  • Headaches
  • Mouth sores, including yeast infection (thrush)
  • Muscle stiffness or aching
  • Night sweats
  • Rashes of different types
  • A sore throat
  • Swollen lymph glands
  • Fever
  • Rash
  • Sweats (particularly at night)
  • Swollen lymph glands
  • Weakness
  • Weight loss


 Affecting organs:

The virus attacks a specific type of immune system cell in the body, known as CD4 helper lymphocyte cells. HIV destroys these cells, making it harder for your body to fight off other infections.



The main treatment for HIV is antiretroviral therapy, a combination of daily medications that stop the virus from reproducing.
