Hi, I just had a question about Hepatitis C. Last month I attended a summer camp, and we all had to wear nametags. One night I noticed red stuff on mine, and thought it was just pasta sauce fromt that night's dinner. I licked my finger and wiped it off, then stupidly put my finger back into my mouth to rewet and clean off the rest. At that point I realized that the red substance was blood. I am prone to canker sores, and am worried that I might have been exposed to HCV. How high is that risk?
