HIV is a virus. It stands for human immunodeficiency virus. It causes deficiency in the human immuno system and destroys immune system cells called CD4 cells. These cells protect the human body from other infections, diseases and other health related issues.
If the human body losses a large number of these cells, it becomes more prone to infections and diseases. In short, HIV is a virus that makes the body more likely to get ill very easily.
AIDS stands for acquired immuno deficiency syndrome. It is the last stage of HIV when the virus becomes life threatening to the human body. It is a condition caused by the HIV virus.
HIV is the virus and AIDS is the condition in which HIV is rampant on the human body. When a person is infected with the HIV virus, he starts to lose CD4 cells but his body doesn’t lose all of them at once. The HIV virus continues to spread if left untreated. It continues to grow slowly over a long period of time and make the body lose CD4 cells.
The HIV virus doesn’t have any cure that can completely wipe it out of the body. But there are treatment available that can reduce the spread of HIV and prevent it from becoming AIDS.
One of the most commonly used treatments against HIV for AIDS prevention is Antiretroviral therapy (ART). It can’t cure HIV but reduces the risk of HIV transmission to others and help patients live healthier lives. CDC has a more detailed explanation about how this treatment works:
HIV treatment involves taking medicines that slow the progression of the virus in your body. HIV is a type of virus called a retrovirus, and the combination of drugs used to treat it is called antiretroviral therapy (ART).
Although a cure for HIV does not yet exist, ART can keep you healthy for many years, ART reduces the amount of virus (or viral load) in your blood and body fluids. ART is recommended for all people with HIV, regardless of how long they’ve had the virus or how healthy they are. ART also reduces your chance of transmitting HIV to others if taken as prescribed.
ART is usually taken as a combination of 3 or more drugs to have the greatest chance of lowering the amount of HIV in your body.
Since HIV is an uncureable virus, it is best to try and prevent HIV infection than trying to treat it.
