PHILADELPHIA (CBS) – The Centers for Disease Control and Prevention want baby boomers to know that they should be aware that Hepatitis C is a serious concern.

Approximately 4 million Americans have the hepatitis C virus and people born between 1945 and 1965 account for three quarters of the infections.

Many people with hepatitis C are not aware they have it and do not receive treatment. If hepatitis C is not detected, it increases a person’s risk for liver cirrhosis, liver cancer and problems with liver function.

The CDC would like all people in this age group tested to see if hepatitis C is an issue and if the test is positive counseling is recommended as well.
