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.
In the meantime, the excess bilirubin in the baby's body causes symptoms of jaundice. Every newborn has elevated bilirubin, but only around 60 per cent of full-term babies will have noticeable symptoms. Treatment isn't usually necessary, unless the baby has very high bilirubin levels, or is premature or sick.
