The method of transmission of hepatitis depends on its type, as the New York Department of Health explains. Hepatitis A, B and C are all transmitted differently.
Hepatitis A is spread after putting a finger or object in the mouth that is contaminated with the stool of someone with the virus, according to the New York Department of Health. The object often looks clean but is still contaminated. Hepatitis B and C contaminate the blood and body fluids. Hepatitis B can be transmitted through sexual contact, while hepatitis C is usually transmitted through needles. Some people are immune to individual forms of hepatitis, and there is a vaccine for types A and B.
