Hepatitis C is a viral infection that affects the liver and can cause acute and chronic illnesses. It is primarily transmitted through contact with infected blood, such as unsafe injections, unscreened blood transfusions, and sharing needles for drug use. While there are effective treatments, including antiviral medications, there is currently no vaccine available for hepatitis C. The focus is on treatment and awareness to manage the infection, and individuals are encouraged to get tested, especially those in high-risk groups.

What You'll Learn
There is currently no hepatitis C vaccine
Hepatitis C is a liver infection caused by the hepatitis C virus (HCV). It is a blood-borne virus, and most people become infected with HCV by sharing needles or other equipment to inject drugs. It can also be transmitted from an infected mother to her baby, through sexual practices that involve exposure to blood, unregulated tattoos or body piercings, and sharing personal items that may be contaminated with infected blood.
There is currently no effective vaccine for hepatitis C. While treatments exist, prevention through vaccination remains a challenge. Organizations like the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) confirm the absence of a hepatitis C vaccine. The focus, therefore, is on treatment and awareness to manage the infection.
Direct-acting antiviral medicines (DAAs) can cure more than 95% of persons with hepatitis C infection. These treatments can reduce the risk of long-term complications, such as liver cancer. However, access to diagnosis and treatment is low. The WHO recommends that testing, care, and treatment for persons with chronic hepatitis C infection can be provided by trained non-specialist doctors and nurses in primary care, harm reduction services, and prisons, making it more accessible and convenient for patients.
Awareness of hepatitis C status is important. Individuals are encouraged to get tested, especially those in high-risk groups, and to engage in preventive practices such as safe drug use and regular medical check-ups. The CDC recommends hepatitis C screening for all adults aged 18 and older and for all pregnant women during each pregnancy. Regular testing is also advised for those with ongoing risk factors.

Treatment and awareness are the focus
Hepatitis C is a liver infection caused by the hepatitis C virus (HCV). It is usually spread when someone comes into contact with infected blood, even in amounts too small to see. This can happen through the sharing of needles and syringes, the transfusion of unscreened blood, unregulated tattoos or body piercings, and sexual practices that lead to exposure to blood. It can also be transmitted from an infected mother to her baby.
There is currently no effective vaccine against hepatitis C. However, treatments are available that can cure the infection and reduce the chance of developing liver disease and liver cancer. Direct-acting antiviral medicines (DAAs) can cure more than 95% of persons with hepatitis C infection. These treatments have few, if any, side effects and minimal expertise and monitoring are required to administer them. The American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) recommend treatment for all people diagnosed with hepatitis C, except pregnant women and children under 3.
Despite the availability of effective treatments, the prevalence of hepatitis C remains high in some parts of the world, particularly in the United States. One possible reason for this is the low access to diagnosis and treatment. In the US, it is estimated that about two and a half million people were chronically infected with HCV during 2017-2016, with more than 67,000 new infections in 2022 alone.
To address this issue, the World Health Organization (WHO) has taken several steps to increase awareness and improve access to testing and treatment. WHO recommends that testing, care, and treatment for hepatitis C can be provided by trained non-specialist doctors and nurses in primary care, harm reduction services, and prisons, making it more accessible and convenient for patients. WHO also organizes annual World Hepatitis Day campaigns to increase awareness and understanding of viral hepatitis.
In addition to these efforts by WHO, other organizations such as the Centers for Disease Control and Prevention (CDC) and the American Association for the Study of Liver Diseases (AASLD) also provide recommendations and guidelines for hepatitis C screening and prevention. Increasing awareness, improving access to testing and treatment, and promoting harm reduction strategies are key focuses in the fight against hepatitis C.

Testing is critical for managing hepatitis C
The hepatitis C virus (HCV) is often asymptomatic, with around 40% of those with chronic hepatitis C unaware of their infection. Without testing, infected individuals can unknowingly transmit the virus to others. Testing allows for timely treatment, which can prevent hepatitis C complications and interrupt transmission.
Hepatitis C testing typically involves a simple blood test to detect the presence of HCV antibodies. If this initial screening is positive, a follow-up HCV RNA test is needed to confirm viremia and the need for treatment. The viral load, or amount of HCV RNA in the blood, is measured before and during treatment to assess response.
The World Health Organization (WHO) recommends testing people in certain high-risk groups more frequently, including blood donors, people with signs of liver disease, migrants from endemic regions, healthcare workers, people who inject drugs, those in prisons, men who have sex with men, transgender people, sex workers, and those with HIV or TB infections.
With improved access to testing and simplified treatment options, hepatitis C management has become more accessible and convenient for patients. Testing is a critical component of hepatitis C management, enabling early detection, treatment, and prevention of transmission.

Hepatitis C is a liver infection
Hepatitis C can cause both acute (short-term) and chronic (long-term) infections. Acute HCV infections are usually asymptomatic, and most do not lead to life-threatening diseases. However, chronic hepatitis C can lead to serious health problems, including liver disease, cirrhosis, liver failure, liver cancer, and even death. It is a leading cause of liver transplants in the United States.
The majority of people infected with HCV may not be aware of their infection as they do not exhibit any symptoms. Some people may experience symptoms such as fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, and jaundice. The only way to know if you have hepatitis C is to get tested through a simple blood test. Early detection and treatment can prevent serious liver damage and improve long-term health outcomes.
While there is currently no effective vaccine against hepatitis C, it can be treated and cured with antiviral medications. Direct-acting antiviral medicines (DAAs) can cure more than 95% of persons with hepatitis C infection. Treatment typically involves 8-12 weeks of oral medication, with few to no side effects. The World Health Organization (WHO) recommends therapy with pan-genotypic DAAs for all adults, adolescents, and children down to 3 years of age with chronic hepatitis C infection.

It is a bloodborne virus
Hepatitis C is a liver infection caused by the Hepatitis C Virus (HCV). HCV is a bloodborne virus, meaning that being exposed to blood from a person who is infected can spread the infection.
HCV is most commonly transmitted through the reuse or inadequate sterilisation of medical equipment, especially syringes and needles in healthcare settings. For example, HCV can be transmitted from accidental needle sticks and breaches in infection control practices in healthcare facilities. It can also be transmitted through the transfusion of unscreened blood and blood products.
The sharing of injection equipment is another common method of transmission. People who inject drugs, including heroin, are at an increased risk of contracting HCV. This is because when a person with HCV injects a drug, some of their blood can remain in the needle, and when another person uses the same needle, they are effectively sending blood carrying the virus into their body.
HCV can also be passed from an infected mother to her baby, although this is less common. It can also be transmitted through sexual practices that lead to exposure to blood, such as among people with multiple sexual partners and men who have sex with men. However, it is important to note that hepatitis C is not often spread through sexual contact.
In addition to the above, HCV can be transmitted through unregulated tattoos or body piercings, as well as the sharing of personal items that may be contaminated with infected blood, even in small amounts.
