My sister told me that her friends Mom's blood workup came back and showed that she has Heptatitis C. She has no idea how that could happen. She didn't fall under the typical causes of the disease. Can anyone tell me how this would happen? I don't know anything about it and my personal question is, if she does have it, is this a person that you shouldn't use the same towel, drink after the person, etc...? I heard a long time ago that people who had the disease more or less should be quarantined! Is that true? Thanks for any info.
