What is the meaning of HIV-1?
HIV-1 is the most common type of Human Immunodeficiency Virus. It attacks your body’s immune system. The virus destroys CD4 cells. These cells help your body fight infections. HIV-1 can severely damage your immune system and lead to Acquired Immune Deficiency Syndrome (AIDS).
What is the history of HIV?
Scientists believe that HIV originally came from a virus particular to chimpanzees in West Africa during the 1930s, and originally transmitted to humans through the transfer of blood through hunting. Over the decades, the virus spread through Africa, and to other parts of the world.
What is the normal CD4 count for a healthy person?
A normal CD4 count is from 500 to 1,400 cells per cubic millimeter of blood. CD4 counts go down over time if you do not take ART. At levels below 200 cells per cubic millimeter, you are more likely to get to a wide variety of OIs, many of which can be deadly.
How do you read CD4 results?
1. 9 Interpreting CD4 results: CD4 count and CD4 percentage
- A CD4 count above 500 is considered “normal”.
- A CD4 count below 350 shows HIV has damaged your immune system.
- If the count is less than 200 your risk of serious infections becomes much higher.
What is a good CD4 percentage?
The average normal CD4 percentage for someone who is HIV negative is about 40%. The normal range is anywhere from about 25% to 65%.
What is a healthy CD4 count?
The CD4 count normal range is 500 to 1500 cell/mm^3. If a patient is left untreated, levels can drop below 200 cells/mm^3, which is one indication for the diagnosis of AIDS.
What does it mean when your viral load is 0?
Having an undetectable viral load does mean that there is not enough HIV in your body fluids to pass HIV on during sex. In other words, you are not infectious. For as long as your viral load stays undetectable, your chance of passing on HIV to a sexual partner is zero.
Can I test positive if my viral load is undetectable?
If you’re undetectable, you will still test positive for HIV. This is expected, and doesn’t mean that your treatment is not working.
What does a viral load of 70 mean?
A ‘blip’ is a viral load result that is just over 50 copies/mL. Viral load should have been undetectable on previous tests and be undetectable again on the next test. Low-level blips are between 50 to 200 and these are most common.
What does a viral load of 120 mean?
People with an undetectable viral load sometimes experience what are called ‘blips’ in their viral load. Their viral load increases from undetectable to a low but detectable level (for example, 120 copies/ml) before becoming undetectable again on the next test. This should not be a cause for concern.
What does a viral load of 60 mean?
People with an undetectable viral load sometimes experience what are called ‘blips’ in their viral load. Their viral load increases from undetectable to a low but detectable level before becoming undetectable again on the next test. For example, your viral load may temporarily rise to 60 copies/ml or 150 copies/ml.
