What Is HIV?
Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, especially the CD4 cells, also known as T cells. These cells help the body fight infections and diseases. When HIV weakens the immune system over time, the body becomes more vulnerable to illnesses and infections.
If HIV is not treated, it can progress to Acquired Immunodeficiency Syndrome (AIDS), which is the most advanced stage of HIV infection. However, with modern medical treatment, many people living with HIV can live long, healthy, and productive lives.
HIV remains one of the most discussed global health conditions, but awareness, education, early diagnosis, and treatment have significantly improved survival rates and quality of life.
What Causes HIV?
HIV is caused by a virus that spreads through certain body fluids from a person who has HIV. These fluids include:
- Blood
- Semen
- Vaginal fluids
- Rectal fluids
- Breast milk
The virus enters the body and gradually damages the immune system if left untreated.

Symptoms of HIV
HIV symptoms can vary from person to person. Some people may not notice symptoms for years, while others experience signs within a few weeks after infection.

Early Symptoms of HIV
The first stage of HIV infection is called acute HIV infection. During this stage, many people experience flu-like symptoms, including:
- Fever
- Headache
- Sore throat
- Fatigue
- Swollen lymph nodes
- Muscle aches
- Skin rash
- Night sweats
- Mouth ulcers
These symptoms may appear 2 to 4 weeks after exposure and can last for several days or weeks.

Chronic HIV Symptoms
After the early stage, HIV may enter a silent phase called chronic HIV infection. During this period, the virus is still active but may not cause noticeable symptoms.
Without treatment, the immune system gradually weakens, leading to symptoms such as:
- Persistent fatigue
- Weight loss
- Frequent infections
- Chronic diarrhea
- Persistent fever
- Skin problems
- Persistent cough

How HIV Is Transmitted
HIV spreads through direct contact with infected body fluids. Common methods of transmission include:

Unprotected Sexual Contact
Having vaginal, anal, or oral sex without protection with someone who has HIV can transmit the virus.

Sharing Needles
Sharing needles, syringes, or sharp objects contaminated with infected blood increases the risk of HIV transmission.

Mother-to-Child Transmission
A mother living with HIV can pass the virus to her baby during pregnancy, childbirth, or breastfeeding if proper treatment is not received.

Blood Transfusion
Although rare today due to strict screening, HIV can spread through infected blood transfusions.

How HIV Is Not Transmitted
HIV does not spread through casual contact. You cannot get HIV from:
- Hugging
- Shaking hands
- Sharing food
- Mosquito bites
- Coughing or sneezing
- Using public toilets
- Sharing utensils
Understanding the facts helps reduce fear and stigma around HIV.

Diagnosis of HIV
Early diagnosis is important because it allows people to begin treatment quickly and protect their immune system.

HIV Testing Methods
Antibody Tests
These tests check for antibodies the body produces against HIV.

Antigen/Antibody Tests
These are common laboratory tests that can detect HIV earlier than antibody-only tests.

Nucleic Acid Tests (NAT)
These tests detect the actual virus in the blood and are usually used in special situations.

When Should You Get Tested?
You should consider HIV testing if:
- You had unprotected sex
- You shared needles
- You have symptoms associated with HIV
- Your partner tested positive for HIV
- You are pregnant
Regular testing is one of the best ways to protect your health and the health of others.

Treatment of HIV
There is currently no complete cure for HIV, but effective treatment allows people with HIV to live normal and healthy lives.

Antiretroviral Therapy (ART)
The main treatment for HIV is Antiretroviral Therapy (ART). These medications reduce the amount of HIV in the body, known as the viral load.
Benefits of ART include:
- Strengthening the immune system
- Preventing progression to AIDS
- Reducing the risk of transmission
- Improving quality of life
- Increasing life expectancy
People taking ART as prescribed can achieve an undetectable viral load, meaning the virus becomes so low that it cannot be sexually transmitted. This concept is known as Undetectable = Untransmittable (U=U).
