UNDERSTANDING HIV
What Is HIV?
Human Immunodeficiency Virus (HIV) is a virus that attacks the body's immune system, specifically targeting CD4 T-lymphocytes, commonly known as helper T cells.
These cells play a critical role in defending the body against infections and diseases.
Without treatment:
- HIV progressively weakens immunity.
- Opportunistic infections become more likely.
- Certain cancers may develop.
- Advanced disease can occur.
Modern treatment has transformed HIV into a manageable chronic condition for many individuals.
Difference Between HIV and AIDS
Many people mistakenly use HIV and AIDS interchangeably.
They are not the same.
HIV
Refers to the virus itself.
AIDS (Acquired Immunodeficiency Syndrome)
Represents the most advanced stage of untreated HIV infection.
With modern antiretroviral therapy, many people living with HIV never develop AIDS.
THE GLOBAL HIV LANDSCAPE
