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.
Jaundice happens when bilirubin builds up faster than a newborn's liver can break it down and pass it from the body. Here are some reasons why: Newborns make more bilirubin than adults do since they have more turnover of red blood cells. A newborn baby's still-developing liver might not be able to remove enough bilirubin from the blood.
