HIV is the infection - the virus. AIDS is the disease caused by unmanaged HIV infection.

Isn't AIDS a syndrome not a disease?

HIV is an infection. In the initial stages it is acute and later on it becomes dormant in your body (although still active, it just reproduces at very low levels). As the virus levels increase in your body, HIV eventually develops into Acquired immunodeficiency syndrome (AIDS). AIDS is the most severe phase of HIV infection. People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic illnesses.

HIV is the name of the Human Immunodeficiency Virus, just as Homo sapiens is the name of the human species.

When infected by HIV, the body can respond in a number of ways. In some cases, the infection is completely suppressed, just as sometimes, we can get infected by a flu virus and never even know we had it - our immune system clears it spontaneously.

Sometimes, the infection takes hold and produces various signs of damage to our systems.

There are a number of possible diagnoses that we can have as a result of HIV infection, but by far the best known is called Acquired Immune Deficiency Syndrome - AIDS. You are diagnosed as having AIDS when you have HIV infection, plus a variety of "AIDS defining conditions", such as:

- Candidiasis of the esophagus, bronchi, trachea, or lungs [(but NOT the mouth (thrush)]
- Coccidioidomycosis, disseminated or extrapulmonary
- Cryptosporidiosis, chronic intestinal (greater than one month's duration)
- Cytomegalovirus retinitis (with loss of vision)......

(....the list goes on)

So HIV is the causative agent for a number of diseases, but is not a disease in itself. AIDS is called a syndrome because it presents as a collection of different signs and symptoms; the underlying cause is infection with HIV, which triggers or causes other infections or disease processes to take hold.
