AIDS is primarily caused by the Human T-Cell Lymphotropic Virus-III (HTLV III). This virus infects and eventually kills T-cells, leading to a weakened immune system. As a result, the body becomes susceptible to various infections. While other factors may contribute to the progression of the disease, HTLV III is the main culprit.

Primary Cause of AIDS
AIDS, or Acquired Immunodeficiency Syndrome, is primarily caused by the Human Immunodeficiency Virus (HIV), specifically the strain designated as HTLV III. Understanding this virus is crucial to comprehending how AIDS develops.
What is HTLV III?
- HTLV III is an early name for HIV, which is a retrovirus that attacks the immune system.
- It primarily targets CD4+ T cells, which are vital for a robust immune response.
How HIV Causes AIDS
- The virus enters the body through blood, sexual contact, or from mother to child during childbirth or breastfeeding.
- Once inside, HIV integrates its genetic material into the host's cells. It replicates, leading to a progressive decline in the number of CD4+ T cells.
- As the immune system weakens, the body becomes increasingly susceptible to opportunistic infections and certain cancers.
Stages of HIV Infection
- Initial Infection: Flu-like symptoms may occur, but many individuals remain asymptomatic for years.
- Chronic Phase: The virus continues to replicate, and CD4+ T cell counts gradually decline.
- AIDS: Diagnosed when CD4+ T cell counts drop below a critical level or when opportunistic infections manifest.
Importance of Early Detection
- Early diagnosis and antiretroviral therapy (ART) can significantly prolong life and improve quality by maintaining immune function and preventing the progression to AIDS.
In summary, option 'C' is correct because HTLV III (HIV) is the virus responsible for the immune system's deterioration, leading to AIDS. Understanding this virus is essential for prevention, treatment, and management of the disease.
