SummaryRead the full fact sheet
- Hepatitis C is a virus that causes inflammation and damage to the liver.
- Many people who live with hepatitis C do not have symptoms until they have had the virus for a long time and there is a lot of liver damage.
- Hepatitis C is a bloodborne virus. In Australia, the main way hepatitis C is spread is through the sharing of injecting equipment.
- There are new treatments, available to all people living with hepatitis C, that cure the virus and improve their health.
- The new treatments available are in tablet form, taken once a day for 8 to 12 weeks. It is much easier to take than older treatments with only minimal side effects.
- You can improve your liver health by eating a well-balanced diet, doing regular exercise, decreasing stress, and reducing the amount of alcohol you drink (or avoiding alcohol altogether).
- See your doctor immediately if you have any symptoms or if you think you have been at risk of infection.
What is hepatitis C?
Current treatment is very effective at curing hepatitis C for more than 95% of people. Treatment cures the infection, decreases inflammation in the liver and reduces the long-term risk of health problems including chronic liver disease and .
Curing hepatitis C also prevents transmission to others. There is no vaccine to prevent hepatitis C infection.
Symptoms of hepatitis C
If you do not have symptoms this does not mean that the virus isn’t causing damage.
When first infected, some people may find:
- dark or darker urine
- yellowing of eyes and skin (this is known as jaundice)
- minor flu-like illness.
These symptoms may disappear within a few weeks, but this does not necessarily mean that the infection has been cleared.
Over time, symptoms that may develop include:
- tiredness and
- flu-like symptoms (chills and )
- where the liver is located
- not feeling hungry (nausea) and indigestion.
Around 30% of people who have been exposed to hepatitis C may clear the virus from their blood naturally, with no treatment, within 6 months. These people no longer have the hepatitis C virus and are not infectious, but will always have hepatitis C antibodies in their blood. The presence of hepatitis C antibodies shows that someone has been exposed to the virus, but does not offer any immunity against hepatitis C.
People can become reinfected after clearing hepatitis C naturally, or after treatment.
Chronic hepatitis C
Approximately 2 out of every 3 people infected with hepatitis C do not clear the infection and continue to carry the virus in their blood for more than 6 months. This is called chronic hepatitis C.
Often chronic hepatitis C does not cause significant health problems until many years after infection. In many cases, people who have chronic hepatitis C do not feel ill.
Symptoms of chronic hepatitis C can include:
- mild to severe tiredness
- loss of appetite
- feeling sick (nausea) and vomiting
- soreness in the upper right side of the stomach (under the ribs)
- increased and
- skin rash.
About 15 to 20% of people who have untreated chronic hepatitis C will develop severe scarring of the liver (). This may take 20 to 40 years, or more, to develop. A small number of people with cirrhosis may then develop liver cancer.
Spread of hepatitis C
Hepatitis C is spread through blood-to-blood contact when blood from a person with hepatitis C enters another person’s bloodstream.
The most common way people become infected with hepatitis C in Australia is by sharing injecting equipment such as needles, syringes, spoons and tourniquets. It is possible to be infected with hepatitis C after only one risk event.
Hepatitis C may also be spread through:
- and – through using equipment that has not been properly cleaned, disinfected or sterilised such as ‘backyard tattoos'. Registered parlours with appropriate infection prevention and control procedures remove the risk of hepatitis transmission
- – any sharps injury associated with the delivery of care or medication
- receiving in Australia prior to 1990 – before hepatitis C virus testing of blood donations was introduced
- medical procedures, blood transfusions or blood products and mass immunisation programs provided in a country other than Australia
- or childbirth – there is a 5% chance of a mother with chronic hepatitis C infection passing on the virus to her baby during pregnancy or childbirth.
Less likely possible routes of transmission of hepatitis C include:
- the sharing of toothbrushes, razor blades or other similar personal items that could have small amounts of blood on them
- sexual transmission – sexual transmission rates of hepatitis C are very low, however the risk is increased with certain sexual practices or circumstances where there is the possibility of blood-to-blood or anorectal fluid-to-blood contact (for example, sex during menstruation, group sex, the use of sex toys, fisting or the use of anorectal douching equipment) that can lead to tears in the mucosal membrane or exposure of open cuts or wounds on the skin to hepatitis C in anorectal fluid. This risk is higher for people living with .
Hepatitis C cannot be transmitted by:
- sharing food, cups or cutlery
- shaking hands or day-to-day physical contact.
Preventing the spread of hepatitis C
There is no vaccine available to prevent a person from being infected with hepatitis C. Recommended behaviours to prevent the spread of the virus include:
- Always use sterile (completely clean) injecting equipment. This can be accessed from your local needle and syringe program (NSP) service.
- Do not share injecting equipment.
- Avoid sharing personal items such as toothbrushes, razors, nail files or nail scissors, which can draw blood.
- If you are involved in body piercing, tattooing, electrolysis or , always ensure that any instrument that pierces the skin is either ‘single use’ or has been cleaned, disinfected and sterilised (via autoclave) since it was last used.
- If you are a healthcare worker, always follow standard precautions (infection prevention and control guidelines).
- Wherever possible, wear single-use gloves if you give someone first aid or clean up blood or body fluids.
- Although hepatitis C is not generally considered to be a in Australia, you may wish to consider practices (using a condom) if blood is going to be present, or if your partner has HIV infection. You may wish to further discuss this issue and personal risks with your doctor.
Hepatitis C and injecting drugs
If you inject drugs, avoid sharing needles, syringes or other equipment such as tourniquets, spoons, swabs or water.
Where possible, always use sterile needles and syringes. These are available free of charge from needle and syringe programs and some pharmacists. To find out where you can obtain free needles, syringes and other injecting equipment, contact on .
Try to wash your hands before and after injecting. If you can’t do this, use hand sanitiser or alcohol swabs from a needle and syringe program (NSP) service.
Hepatitis C and blood spills
When cleaning and removing blood spills, use standard infection prevention and control precautions at all times:
- Cover any cuts or wounds with a waterproof dressing.
- Wear single-use gloves and use paper towel to mop up blood spills.
- Use protective eyewear.
- Clean the area with warm water and detergent, then rinse and dry.
- Place used gloves and paper towels into a plastic bag, then seal and dispose of them in a rubbish bin.
- Wash your hands in warm, soapy water then dry them thoroughly.
- Put bloodstained tissues, sanitary towels or dressings in a plastic bag before throwing them away.
Diagnosis of hepatitis C
If you are at risk of hepatitis C infection or think you may have been exposed to hepatitis C in the past, see your doctor for an assessment of your liver health. This will include blood tests and possibly a non-invasive test for liver damage (called a ).
It may take 2 to 3 months (or sometimes longer) from the time of infection until a blood test can detect antibodies to hepatitis C, so there is a ‘window period’ during which you cannot tell if you are or have been infected. In this time, take precautions to prevent the potential transmission of the virus.
There are 2 blood tests used to diagnose hepatitis C. Usually these can be done at the same time but sometimes they will be done separately.
The first test known as a ‘hepatitis C antibody test’ can tell you whether you have ever been exposed to hepatitis C.
The second test is called ‘hepatitis C PCR’, which will be done if the antibody test is positive. This determines if the virus is still present in your blood or liver or if you have already cleared the infection.
If you have cleared the virus or had successful treatment to cure it, the PCR test will be negative.
If you have had hepatitis C in the past, you could ask to skip the antibody test as this will be positive. Once you have been exposed to hepatitis C, you will always have the antibodies.
Treatment of hepatitis C
Hepatitis C is treated with antiviral medications that aim to clear the virus from your body.
Since 2016, new all-tablet (oral) treatments have greatly improved the outcomes for people with hepatitis C. These treatments can cure more than 95% of individuals with chronic hepatitis C and the new tablets are used to treat all hepatitis C strains (genotypes). They are effective for people with no liver damage and those who have more advanced liver damage or cirrhosis.
There are no restrictions on accessing treatment – it is available for all adults with a card. People under 18 are able to access treatment and it is recommended they are referred to a pediatrician experienced in the treatment of hepatitis C. For people without a Medicare card, discuss your options with your doctor.
Talk with your doctor about treatment options and the potential for interactions with other medications, herbal preparations and other drugs. If you take prescribed medication this will be managed so you can access treatment.
In general, if you have hepatitis C you will feel better if you:
- Get treated and cure the virus.
- Avoid drinking alcohol.
- Eat a .
- Do (although always rest when tired).
- Consult your doctor regularly.
Side-effects of treatment for hepatitis C
There may be some side effects related to hepatitis C medicines, however the new tablets are generally very well tolerated and people feel well taking them. Many people report beginning to feel better whilst taking the medication.
Mild side effects may include:
Usually these side effects improve after a week or so of taking the medication.
