Human Immunodeficiency Virus (HIV). HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body cannot get rid of HIV. That means that once you have HIV, you have it for life.
Infant jaundice is most often caused by an excess of bilirubin. Bilirubin is the waste that remains after hemoglobin (the predominant protein in red blood cells) is released from the breakdown of the red blood cells that carry oxygen throughout the body.
Newborn jaundice occurs when a baby has a high level of bilirubin in the blood. Bilirubin is a yellow substance that the body creates when it replaces old red blood cells. The liver helps break down the substance so it can be removed from the body in the stool.
