There are actually variations of the virus from A through G. They are all viruses that attack the liver. Hepatitis A & E are associated with fecal matter. People who work in food preparation tend to easily spread this one around. They use the restroom, don't wash the hands and it ends up in your food. Or you eat some fish that was living in contaminated water and you get it. So, food and water spread this type. You are probably concerned with the B, C, & D types. It is spread through blood, semen, and contaminated needles. Hepatitis G is the "we don't know what the hell this one is, but it's different from all the others" category. They are discovering even more forms of this virus that go beyond this list and some that are of particular danger to people with AIDs. When you say multiple injections with needles not shared, I assume you mean multiple injections with a new needle being used for each injection every time. If you are doing that, you shouldn't have to worry about contracting anything.
