Know about AIDs

AIDS (Acquired Immunodeficiency Syndrome) is the most advanced stage of infection caused by the Human Immunodeficiency Virus (HIV). The virus targets the immune system, destroying crucial white blood cells (CD4 cells). Without treatment, the body loses its ability to fight infections and cancers, eventually progressing to AIDS. [1, 2]

Because understanding the disease is vital to both health and community support, here is a clear breakdown of everything you need to know.

What is the Difference Between HIV and AIDS?

• HIV is the virus itself. Having HIV does not mean you have AIDS.

• AIDS is the final, most severe stage of HIV infection. A person is diagnosed with AIDS when their immune system is severely damaged or when they develop specific "opportunistic infections". [1, 2, 3, 4]

Transmission

HIV is spread exclusively through specific bodily fluids: blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk. [1]

• Most common: Unprotected sexual contact or sharing needles/syringes used for intravenous drugs.

• Mother to child: Can be transmitted during pregnancy, childbirth, or breastfeeding.

• Note: HIV cannot be spread through casual, everyday contact (such as hugging, shaking hands, sharing toilets, or saliva). [1, 2]

Stages of Infection

1. Acute Infection: Develops 2 to 4 weeks after exposure. Many people experience flu-like symptoms (fever, fatigue, swollen lymph nodes) as their immune system mounts a response. [1, 2, 3]

2. Clinical Latency (Chronic HIV): The virus continues to multiply but at very low levels. People often have no symptoms and can feel completely fine, though the virus can still be transmitted. [1, 2, 3, 4, 5]

3. AIDS: The most advanced stage. The immune system becomes severely compromised (CD4 count drops below 200 cells per cubic millimeter). People at this stage are highly susceptible to severe illnesses. [1, 2, 3]

Treatment and Management

While there is currently no cure for HIV/AIDS, medical advancements have revolutionized how it is treated. [1]

• ART (Antiretroviral Therapy): This daily medication regimen controls the virus so well that it stops destroying the immune system.

• Undetectable = Untransmittable (U=U): When a person with HIV takes ART consistently and achieves an "undetectable" viral load, they cannot transmit the virus to their sexual partners. [1, 2]

Prevention

Modern science has created highly effective preventative tools: [1, 2, 3]

• PrEP (Pre-Exposure Prophylaxis): Daily medication for individuals at high risk of contracting HIV to prevent infection.

• PEP (Post-Exposure Prophylaxis): Emergency medication taken within 72 hours of a potential exposure to block the virus.

• Condoms: Consistently using condoms dramatically lowers the risk of transmission. [1]
