If your doctor tells you that you've got hepatitis, you'll need to find out which type he's talking about. There are five kinds, and each has different causes. They share one thing in common: Hepatitis infects your liver and causes it to get inflamed.
Sharing needles and other equipment (such as cotton, spoons, and water) used to inject drugs.
Having your ears or another body part pierced, getting a tattoo, or having acupuncture with needles that have not been sterilized properly. The risk of getting hepatitis C in these ways is very low.
Working in a health care environment where you are exposed to fresh blood or where you may be pricked with a used needle. Following standard precautions for health care workers makes this risk very low.
