You can develop hepatitis C by coming into contact with the blood of a person with the virus. This can happen by sharing drug equipment, getting a tattoo or piercing at a place with poor infection control, and other ways.
Hepatitis C is an infection caused by the hepatitis C virus (HCV). It can lead to severe liver damage, so it’s important to know all the ways it can be transmitted.
This can be tricky: Many people with hepatitis C can’t identify the source of their infection.
People develop hepatitis C by coming into contact with the blood of someone who has the virus. This can happen in several different ways.
Keep reading to find out all the ways that hepatitis C can be transmitted, what increases your risk, and why testing is so important.
One of the
Since drug use can affect judgment, people may repeat behaviors like needle sharing.
Commercially licensed tattooing and piercing businesses are generally safe.
More informal settings may not have adequate safeguards to help avoid the spread of infections. Receiving a
Prior to 1992, receiving a blood transfusion was a significant risk factor for contracting HCV. However, this route of transmission is now very rare.
According to the
In rare cases, HCV can be spread through nonsterile medical equipment. This can occur due to things such as:
- reusing a needle or syringe that someone with hepatitis C has already used
- mishandling of multidose drug vials or intravenous drugs such that they become contaminated with the blood of someone with hepatitis C
- not properly sanitizing medical equipment
Consistently using appropriate infection control measures can limit this type of transmission. From 2008 to 2019, there were only
Another way that hepatitis C gets transmitted is through the sharing of personal hygiene products that have come into contact with the blood of someone with HCV.
Some examples include things like razors, toothbrushes, and nail clippers.
According to the
Certain sexual behaviors have a higher risk than others when it comes to increasing your chances of contracting the virus.
- having sex without condoms or other barrier method with more than one sexual partner
- having a sexually transmitted infection or HIV
- engaging in sexual activity that could cause bleeding
Birthing parents with hepatitis C can pass on the virus to their baby during childbirth. However, this only occurs in about
It’s also possible to get hepatitis C through an accidental injury, such as getting stuck with a needle that has come into contact with blood that contains HCV. This type of exposure often occurs in a healthcare setting.
However, the risk of contracting hepatitis C due to something like a needlestick is still rather low. It’s estimated that only about 1.8% of occupational exposures to HCV lead to an infection, although this number may be even lower.
- eating with utensils shared by someone with hepatitis C
- holding hands, hugging, or kissing someone with hepatitis C
- being near someone with hepatitis C when they cough or sneeze
- nursing (babies can’t get hepatitis C through breast milk)
- food and water
Can hepatitis C be transmitted through saliva?
Hepatitis C does not pass through saliva. It’s a bloodborne virus. You can only contract the virus by coming in contact with blood that has the virus.
Some factors can increase your risk of developing hepatitis C. These include:
- current or past use of injection drugs
- exposure to HCV through an injury such as a needlestick
- being born to a mother who has HCV
- getting a tattoo or piercing using nonsterile equipment
- receiving a blood transfusion or organ transplant prior to 1992
- receiving clotting factors prior to 1987
- being on kidney dialysis (hemodialysis)
- living or working in a prison
Some people with HCV will clear their infection. However, in
Medications are now available to help clear HCV from your body. According to the CDC,
Because your body doesn’t generate a strong immune response to HCV, it’s possible to contract the virus again. While the rate of reinfection
- inject drugs
- have HIV
- engage in sexual activities that may lead to bleeding
People with hepatitis C can’t currently donate blood. The American Red Cross eligibility guidelines prohibit people who have ever tested positive for hepatitis C from donating blood, even if the infection never caused symptoms.
The Department of Health and Human Services (HHS)
A blood test is one of the only ways to confirm a diagnosis of hepatitis C. Additionally, hepatitis C often has no visible symptoms for many years.
Because of this, it’s important to undergo testing if you believe you’ve been exposed to the virus. A timely diagnosis can help ensure you receive treatment before permanent liver damage occurs.
One-time HCV testing is recommended for people who:
- have HIV
- were born to a birthing parent with HCV
- previously injected drugs
- previously received kidney dialysis
- received a blood transfusion or organ transplant prior to 1992 or clotting factors prior to 1987
- were exposed to HCV-positive blood through an accident, such as a needlestick
Some groups should receive more routine testing. These groups include people currently using injected drugs or receiving kidney dialysis.
HCV can be spread through contact with the blood of someone who has the virus. This most commonly happens by reusing drug equipment.
It can also occur via needlesticks, sharing hygiene items, and nonsterile tattooing or piercing practices. Sexual transmission is rare.
Knowing the risk factors for contracting HCV can help prevent transmission of the virus. If you believe you may have hepatitis C, talk with a doctor about testing and seek early treatment. This can help reduce your chance of liver damage.
