How Do I Know If I Have Hiv-1? Early Symptoms And Treatment Options
Millions of people around the world are infected with the human immunodeficiency virus (HIV). But many people don't know that there are two main types: HIV-1 and HIV-2. Read on to learn more about the most common types of HIV, their symptoms, and treatment options.

What is HIV?
HIV is a virus that attacks white blood cells (WBCs) in your immune system, called T helper cells or CD4 cells. White blood cells help protect your body from disease and injury.
This can make you susceptible to opportunistic infections (OIs) that take advantage of your weakened immune system. When OI does occur, they tend to be more severe and occur more frequently. Examples of HIV-related OIs include tuberculosis and pneumonia.
How is HIV-1 different from HIV-2? What is the difference?
HIV-2 is much rarer than HIV-1. HIV-2 occurs primarily in West Africa, with some cases reported in Asia, Europe, South America, and the United States.
Both types cause similar symptoms and are associated with the same infectious diseases. HIV-2, however, progresses more slowly. This is because people with this type tend to carry a lower viral load. Lower levels of the virus make it more difficult for people to spread from one person to another.
If left untreated, both types can progress to the most serious stage of infection, acquired immunodeficiency syndrome (AIDS).
How is HIV-1 transmitted to others?
HIV-1 is transmitted through direct contact with body fluids that contain the virus. This includes:
- Blood
- Breast milk
- Pre-ejaculatory and semen
- Rectal fluids
- Vaginal fluids
People with HIV can spread the virus to other people, even if they don't show any symptoms. However, for this to happen, a certain amount of the virus must be present in their body fluids. If her viral load is undetectable, she can't spread the virus to other people.
What are the early warning signs of HIV-1?
Early symptoms of HIV-1 usually appear 2 to 4 weeks after infection. These symptoms are often similar to those of the flu, such as:
- Cough
- Diarrhea
- Fever and chills
- Headache
- Joint pain
- Muscle pain
- Night sweats
- Throat and mouth pain
- Swollen lymph nodes, most often in the neck
What are the later symptoms of HIV-1?
After you recover from these initial symptoms of HIV, you may have few or no symptoms for a while. But eventually, as the virus spreads through your body and destroys your CD4 cells, you may develop chronic (long-term) symptoms.
These include some of the early symptoms of HIV and other serious infections or diseases, such as:
- Pneumonia
- Herpes zoster (shingles)
- Thrush (oral yeast infection)
What are the treatment options for HIV-1?
Although health experts have not yet found a cure for this viral disease, antiretroviral therapy (ART) can help:
- Control the amount of virus in your body
- Slow down how quickly the virus spreads through your body
- Prevent health complications
Effective ART treatment usually involves a combination of at least 2 drugs from 2 or more drug classes, some of which are combined into a pill that you take once a day.
Intravenous injections may also be an option. These long-acting injections are usually given every 1 to 2 months. You may be able to switch to the HIV treatment vaccine if you:
- No known allergies to the drugs it contains
- No previous HIV treatment failures
- Undetectable viral load or viral suppression (less than 200 copies of the virus per 200 ml of blood)
To determine how well your immune system is working and how well your HIV treatment is working, your doctor will order lab tests to measure your viral load and CD4 cell count.
