Can I still hug and kiss my family members if I have hepatitis c?

Absolutely. Casual contact like hugging, kissing, and sharing dishes will not transmit hepatitis c. Nursing a baby won't. Heterosexual sex with a monogamous long term partner is very unlikely to transmit hepatitis c. However, do not share anything that might have even tiny amounts of blood on it like toothbrushes, razors, nail or hair clippers.
Usually yes. Hugging and kissing are not known to spread hepatitis c unless there is some wound that has some blood. Hepc viruses can be transmitted if there is some bleeding occurring. One can ask his doctor about what activities are safe and unsafe, if one has hepc.
