Learn About HIV

HIV (Human Immunodeficiency Virus) is a virus that attacks the body’s immune system. Without treatment, it destroys CD4 white blood cells, making the body vulnerable to infections. Today, with early diagnosis and Antiretroviral Therapy (ART), HIV is a highly manageable, chronic condition that allows individuals to live long, healthy lives. [1, 2, 3]

A comprehensive, easy-to-read breakdown of everything you need to know about HIV covers these core areas:

1. Transmission

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

• Primary ways it spreads: Unprotected sex with an infected partner and sharing needles or syringes used for drugs or tattooing.

• Mother-to-child: It can be passed during pregnancy, childbirth, or breastfeeding.

• What it does NOT spread through: Casual everyday contact like hugging, shaking hands, sharing cutlery, or toilet seats. [1, 2, 3, 4]

2. Symptoms

Many people experience no symptoms at all for years. However, some go through stages: [1]

• Acute Infection: 2 to 4 weeks after exposure, some people experience flu-like symptoms (fever, swollen glands, rash, fatigue).

• Clinical Latency: The virus continues to multiply but at very low levels. Without treatment, this phase lasts an average of 10 years.

• AIDS: This is the most advanced stage of HIV. The immune system becomes severely damaged, leading to life-threatening "opportunistic infections". [1, 2, 3, 4, 5]

3. Testing

Testing is the only definitive way to know your HIV status. [1]

• Modern tests look for HIV antibodies and antigens (like the P24 protein) in a blood sample.

• It is recommended that everyone get tested for HIV at least once in their lifetime, with more frequent testing (every 3 to 6 months) for sexually active at-risk populations. [1, 2]

4. Treatment (ART)

There is no cure for HIV, but proper medical care effectively controls the virus. [1]

• ART: Antiretroviral therapy involves taking a daily combination of medications (often a single pill) or, in some cases, taking regular long-acting injections. [1, 2]

• U=U (Undetectable = Untransmittable): When on effective ART, the amount of HIV in the blood drops to undetectable levels. At this point, the virus cannot be sexually transmitted to partners. [1, 2]

5. Prevention

• Safe Sex: Consistently using condoms drastically reduces the risk of transmission. [1]

• PrEP (Pre-Exposure Prophylaxis): Daily medication taken by HIV-negative individuals who are at high risk to prevent them from catching the virus. [1]

• PEP (Post-Exposure Prophylaxis): Emergency medication taken to prevent HIV after a potential exposure (e.g., condomless sex or needlestick injury). It must be started within 72 hours. [1, 2, 3, 4, 5]
