What is HIV?
Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), which are crucial for fighting off infections. HIV weakens the immune system, making individuals susceptible to a wide range of opportunistic infections and certain cancers. It’s primarily spread through specific bodily fluids – blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk – typically during unprotected sex, sharing needles, or from mother to child during pregnancy, childbirth, or breastfeeding.
What is AIDS?
Acquired Immunodeficiency Syndrome (AIDS) is not the same thing as HIV. AIDS is the most advanced stage of HIV infection. It occurs when the immune system has been severely damaged by HIV, leaving the individual vulnerable to life-threatening illnesses. A diagnosis of AIDS is typically made when a person with HIV has a very low CD4 cell count (below 200 cells per cubic millimeter of blood) or develops certain opportunistic infections or cancers. According to the Centers for Disease Control and Prevention (CDC), AIDS is defined by specific criteria related to immune function and the presence of opportunistic illnesses.
HIV Infection vs. AIDS: A Timeline
The progression of HIV infection can vary significantly from person to person. Without treatment, the typical stages are:
- Acute HIV Infection (2-4 weeks): Flu-like symptoms are common.
- Clinical Latency (Chronic HIV Infection): The virus continues to replicate, but at low levels. Individuals may experience no symptoms for years.
- AIDS: The immune system is severely compromised,leading to opportunistic infections and cancers.
though, with effective antiretroviral therapy (ART), individuals with HIV can live long and healthy lives and may never develop AIDS. ART reduces the viral load (the amount of HIV in the blood) to undetectable levels, preventing immune system damage and transmission of the virus.
ART involves taking a combination of medications that suppress HIV replication. It is not a cure for HIV,but it can:
- Reduce the viral load to undetectable levels.
- Improve immune function.
- Prevent progression to AIDS.
- Reduce the risk of transmitting HIV to others (Undetectable = Untransmittable, or U=U).
The National Institutes of Health (NIH) AIDSinfo provides comprehensive information on ART regimens and guidelines.
Prevention
Several strategies can prevent HIV transmission:
