In the United States, there are approximately 30.000 new cases of Hepatitis C each year. That's 30,000 of over 300 million people, or roughly 0.00001 of 1%. And 40% of that 30,000, acquire the disease by IV drug use. So if you have never been an IV drug abuser, your chances now drop to 0.000006 of 1%. And, it really isn't that easy to get.
Hepatitis C is spread by direct, blood-to-blood contact. Ways of acquiring this disease include: Hemophilia, hemodialysis, organ transplant, IV drug use, blood transfusion (prior to 1992), needle-stick injury, tattooing, body piercing, and sexual activity with multiple partners.
Also, most experts estimate that approximately one-quarter to one-third of people initially infected with Hep C, will naturally clear the virus without treatment thanks to an effective immune response. There is also treatment for Hepatitis C, and approximately 50% of those treated will respond favorably.
I'm hopeful that this information might reassure you that your chances of acquiring Hepatitis C from day-to-day routine, is exceedingly rare.
I would also suggest that you consider some form of therapy that may help to alleviate your fears.
The very best to you, Skleep!... Chuck
