What precautions should I take with other people if I have hepatitis?

Depends on the virus. Hep a is passed fecal to oral hep b is extremely contagious and is in all body fluids hep c is less contagious than hep b and is only passed via blood. Always practice safe sex.
Depending on kind. Of hepatitis... alcoholic hepatitis, steatohepatitis (fatty liver) or any drug-related hepatitis is not contagious in the least. Hep A is transmitted by fecal-oral contamination. HBV and HCV are transmitted via blood, HBV and VERY VERY rarely HCV via sexual contact. Should avoid all blood-to-blood contact with latter 2, kissing/ utensil sharing etc is fine.
