In general, hepatitis C transmission requires direct blood exposure. It is not an STD, so I don't keep up on the details. But if you haven't shared injection equipment with an infected person and if you're not a health care worker subject to injuries with sharp instruments, you need not worry about it. Hepatitis B is more easily transmitted and includes sex as a common route. Most infected people (with either virus) have no symptoms; the only way to be certain you aren't infected is to have blood tests at least 6-8 weeks after the last possible exposure.
You'll probably get more reliable information than I can provide from CDC (www.cdc.gov, then search for hepatitis) and from the American Liver Foundation.

You should be using universal precautions with every patient. If you are concerned and are indeed a health care worker, your employee health dept would be happy to test you at no charge. Most certainly will, if you ask.
To put it in perspective (although the experience of a single person means little), I have been a nurse for 28 years and am exposed to blood daily. My husband has also had chronic hep C for 20 years or more. We have always had unprotected sex. I have not gotten Hep C either from him, nor my job, in all that time.
If you use universal precautions at work, you should have no reason to be concerned. If you have an overt exposure, see employee health for testing. Of course, you've had your HepB series.
I need to make my actual questions more specfic in nature. I know that Hepatitis C is spread through blood but my question concerns the degree of risk with body fluids that may contain blood (although it may not be visible)....
