How long does latent HIV last?
According to HIV.gov, latency in HIV infection can last up to 10 or 15 years. This means that the virus is replicating much slower than before. But it doesn't mean that HIV is gone, nor does it mean that the virus can't be transmitted to others.
What stage of HIV is clinical latency?
The second stage of HIV infection is chronic HIV infection (also called asymptomatic HIV infection or clinical latency). During this stage, HIV continues to multiply in the body but at very low levels. People with chronic HIV infection may not have any HIV-related symptoms.

Why is antiretroviral therapy important?
It occurs when the immune system is damaged to the extent that it can no longer fight off infections. Taking antiretroviral drugs keeps the immune system strong enough to prevent HIV from progressing to this stage. Without treatment, the viral load continues to increase and the CD4 cell count continues to drop.
How does antiretroviral therapy help?
Antiretroviral therapy keeps the immune system healthy and reduces the risk of transmitting the virus to virtually zero. The sooner a person receives a diagnosis, the sooner they can begin treatment. Early treatment can improve the person’s outlook and lower the risk of the virus passing on to others.
What happens to the CD4 cell count in stage 3 HIV?
Without treatment, the viral load continues to increase and the CD4 cell count continues to drop. A person will receive a diagnosis of stage 3 HIV if their CD4 cell count drops under 200 cells per cubic milliliter. . Symptoms at this stage vary greatly, as they tend to stem from specific opportunistic infections.

What does it mean when you have an undetectable viral load?
An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. People with HIV who maintain an undetectable viral load have effectively no risk of transmitting HIV to their HIV-negative partner through sex. There are three stages of HIV infection:
How many cells does HIV have?
People with HIV are diagnosed with AIDS if they have a CD4 count of less than 200 cells/mm 3 or if they have certain opportunistic infections. Once a person is diagnosed with AIDS, they can have a high viral load and are able to transmit HIV to others very easily.

The first noticeable stage is primary HIV infection. This stage is also called acute retroviral syndrome (ARS), or acute HIV infection. Because HIV infection at this stage usually causes flu-like symptoms, it’s possible for someone in this stage to think their symptoms are due to a severe flu rather than HIV. Fever is the most common symptom.
What is latent infection?
Latency causes a break in symptoms. After initial exposure and possible primary infection, HIV may transition into a stage called clinically latent infection. It’s also referred to as asymptomatic HIV infection due to a noticeable lack of symptoms. This lack of symptoms includes possible chronic symptoms.

Other names for this stage are the asymptomatic stage or clinical latency. At this stage, you still have the virus in your body but at low levels. It’s possible you won’t notice any symptoms. But as long as the virus is at detectable levels, you can pass the infection to another person.
Stage 3: AIDS
When a chronic HIV infection moves on to AIDS, the amount of HIV in the blood shoots up and the amount of your infection-fighting immune cells drops. Doctors diagnose AIDS when these cells, called CD4 cells, drop below 200 per cubic millimeter of blood.
