Can HCV be spread within a household?

Yes/No. Hepatits c is only passed by blood. So, one should not share razors or toothbrushes in the household if they have hepatitis c. One should probably also retain from sexual intercourse during their menses. Otherwise, someone with hepatitis c should not be able to spread it within his/her empty household.
Yes. Hepatitis c can be spread by small amounts of blood. So, it is important not to share razors, toothbrushes, nail clippers, etc. If someone with hepatitis c gets a cut, they need to clean any spills with bleach. But, most contact like hugging, kissing, sharing dishes, and changing diapers will not transmit hepatitis c. Hetero sex with a monogamous partner also has a low risk of transmission.
