Once you've learned what situations make you likely to catch it, though, you can take steps to protect yourself or get diagnosed and treated.
Who’s at Risk?
The odds are higher that you’ll get hepatitis C if you:
Had a blood transfusion before 1992. A screening test for HCV went into use that year. Before then, this was the main cause of most new cases in the U.S. With routine blood screening for HCV and improvements in the test in mid-1992, transfusion-related hepatitis C has virtually disappeared.
Use needles to take illegal drugs. This is one of the most common ways to get hep C. Up to 80% of new users get the disease within 6 to 12 months.
Snort cocaine. People who share straws or other tools to inhale this drug raise their risk.
Are on dialysis . You can get the disease from equipment that isn’t properly cleaned or should have been thrown away but was reused.
Have a spouse or partner who has it, or care for someone who does. When you're in close daily contact with an infected person, that puts you at risk.
Have body piercings or tattoos. Equipment and supplies can be infected with HCV, but this type of infection doesn’t happen often. To be on the safe side, make sure all tools are sterile or disposable, even the tattoo ink.
Were born to a mother with hepatitis C . Moms can pass the disease to babies, but it doesn’t happen all the time. If the mother has HIV and hepatitis C, there’s more of a chance the baby will get infected.
Who Should Get Tested?
Some doctors say you should get tested at least once no matter what. Definitely get screened if any of these things apply to you:
How to Lower Your Odds of Infection
There’s no effective vaccine against HCV. Take some precautions in high-risk situations. If you’re a health care worker, be careful with blood. If you have sex with more than one partner, use condoms. And if you use drugs, don’t share needles, syringes, or anything that goes up your nose.
Spouses, partners, and others in close contact with people who have hep C should not share toothbrushes and razors. If you have the disease, cover your wounds and throw out blood-soaked bandages, tampons, or pads. Don’t let anyone else in the house touch them.
