Hepatitis C Questions and Answers for the Public
Can hepatitis C virus be spread through sexual contact?
Yes, but the risk of transmission from sexual contact is believed to be low. The risk increases for people who have multiple sex partners, have a sexually transmitted disease, engage in rough sex, or are infected with HIV.
How is hepatitis C spread?
Hepatitis C is usually spread when blood from a person infected with the hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the hepatitis C virus by sharing needles or other equipment to prepare or inject drugs. Before 1992, hepatitis C was also commonly spread through blood transfusions and organ transplants. After that, widespread screening of the blood supply in the United States virtually eliminated this source of infection.
People can become infected with the hepatitis C virus during such activities as:
Sharing needles, syringes, or other equipment to prepare or inject drugs
Needlestick injuries in health care settings
Being born to a mother who has hepatitis C
Less commonly, a person can also get hepatitis C virus through
Sharing personal care items that may have come in contact with another person’s blood, such as razors or toothbrushes
Having sexual contact with a person infected with the hepatitis C virus
Getting a tattoo or body piercing in an unregulated setting
Hepatitis C virus is not spread by sharing eating utensils, breastfeeding, hugging, kissing, holding hands, coughing, or sneezing. It is also not spread through food or water.
