To answer your question, JAUNDICE is not contagious coz it's not a disease. It's a symptomatic sign that something is wrong with your body:

1. You may have weak blood cells, you need vitamin supplements (B complex, Iron, etc)supplements

2. You may have some liver problems: do you take any mecidine? do you drink alcoholic beverages?

3. does your family has history of jaundice?
