If you do your proper research and pick a clean, reputable shop with an up to date license, your risks for Hepatitis are low. You always want to make sure they are strict about sterilization -- if the atmosphere in the shop is dirty, dont get your tattoo there.
Yes, there is a risk of infection, but think about this : every time you get an open sore on your body, there is a risk for infection. As long as you care for the tattoo properly, like you would any cut or scrape, the tattoo will treat you right. The same concept goes for blood poisoning -- keep the tattoo neat and clean, and blood poisoning should not be a worry.
If you care for your body art, it will care for you.
