Hello and thank you for your question,
Anyone who is a carrier for Hepatitis C can give it to people they come in sexual contact with or by sharing needles (for example, if someone is a drug user and shares needles). Also, if someone with Hepatitis C donates blood, the person who will receive the blood, will most definitely get Hepatitis C.
What is true is that the rate of transmission of Hepatitis C through sexual contact is not very high, however, it still exists and someone with Hepatitis C should take all the precautions not to pass the disease to the sexual partner.
I hope you find this information helpful. Please feel free to follow-up with any other questions you might have.

Being pregnant and having Hepatitis C will not affect the baby during pregnancy, however, during the birth/delivery, the virus can get transmitted to the baby if the baby's blood and mom's blood comes in contact. However, the virus doesn't always get transmitted so no, the baby will not definitely have Hepatitis C because not all mom's will transmit the virus.
This may sound a bit confusing. The bottom line is that yes, virus can be transmitted to the baby during delivery but it is not a 100% certainty that it will. There is probably higher chance that it wouldn't.
Let me know if you have any other questions,
