Anyone can get the hepatitis C virus. But unlike a cold or flu virus, HCV isn’t easy to catch. The virus is transmitted only by direct contact with human blood that contains the virus. There are several ways infection can occur.
Whose at Risk?
Those at risk of being infected with hepatitis C virus include:
- People who have used illegal drugs, such as heroin and cocaine. The use of shared needles, common among drug users, can easily transmit the virus. Small amounts of contaminated blood remain on the needle, syringes, and other materials used in injecting or snorting drugs. Even if you injected drugs just once or a few times, many years ago, you could have been exposed to HCV. Also, people who share a straw to snort cocaine may be at increased risk because the cocaine can cause microscopic bleeding in the nose.
- People who were treated for blood-clotting problems, such as hemophiliacs, with a blood-clotting product made before 1987.
- People who received blood from a donor who was later found to have tested positive for HCV.
- People who received a blood transfusion or organ transplant before July 1992, when health officials began screening blood and organ donors for HCV. Before screening began, experts estimate, one out of every 200 units of transfused blood contained the virus. Today, for every 1,935,000 blood transfusions, only one carries the virus.
- Patients who’ve ever been on long-term kidney dialysis, who run an elevated risk because of frequent transfusions.
- Health care workers who have been exposed to HCV-positive blood, typically through needle sticks, splashes to the eye, or other contact. Studies show that about three health care workers out of 100 who receive accidental needle sticks with HCV-infected blood will become infected.
- Children born to HCV-positive mothers. About 4 out of every 100 infants born to infected mothers are infected with the virus, but the risk is higher if the mother has both hepatitis C and HIV. Infection occurs at the time of birth, through contact with blood. Unfortunately, doctors haven’t yet discovered a way to prevent transmission to newborns.
- People who receive surgery or other invasive medical treatments in countries that don’t screen for hepatitis C. There’s a possibility that you might receive a contaminated transfusion.

What about tattooing?
Several studies have shown there is no link between licensed commercial tattooing parlors and HCV infection, “but transmission of Hepatitis C (and other infectious diseases) is possible when poor infection-control practices are used during tattooing or piercing,” according to the Centers for Disease Control and Prevention (CDC).

The agency advises people thinking about getting tattoos or body piercing to consider the health risks. It’s possible to get infected with HCV, the CDC says, if the tools used to have someone else’s blood on them, or if the piercer or tattoo artist fails to use proper hygiene, such as washing hands, sterilizing tools, and using disposable gloves.
Is it possible to contract HCV from a shared razor or toothbrush?
There are no documented cases of transmission, but the CDC warns that people should not share toothbrushes, razors, or other personal care items: They might have small amounts of infected blood on them.
If you or someone in your household is infected with HCV, it’s very important to take steps to prevent transmission. Do not share personal items such as toothbrushes, razors, or manicuring scissors — supplies that could be contaminated with tiny flecks of blood. Avoid contact with open cuts or sores.
The CDC stresses that the hepatitis C virus is NOT spread by casual contact or by breastfeeding, hugging or kissing, sneezing, coughing, or sharing utensils, drinking glasses, food, or water.
