Asking the questions about hepatitis C to a doctor is the best. However, if the person suffering from hepatitis is not you, but your loved one, you might not have an occasion to talk to a doctor.

Hepatitis C is an infectious disease affecting primarily the liver and caused by the virus.
The patient often shows no symptoms and this is why the large number of the infected people is not diagnosed until a much later stage.
The untreated chronic hepatitis C infection may lead to liver scarring (fibrosis) and ultimately to cirrhosis, liver failure or liver cancer
