Hepatitis C is a viral infection that causes inflammation and damage to the liver. It is caused by the Hepatitis C Virus (HCV) and is spread through contact with infected blood. Many people with Hepatitis C do not exhibit any symptoms, but the infection can cause both acute (short-term) and chronic (long-term) illness. While it is not clear if Hepatitis C can cause infections around the muscles, the disease can lead to several other complications, including liver cirrhosis, liver cancer, and liver failure.

| Definition | Hepatitis C is a viral infection that affects the liver. |
| Cause | Caused by the hepatitis C virus (HCV) |

What You'll Learn
Hepatitis C is a liver disease caused by the HCV virus
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). It spreads primarily through contact with infected blood, often when people share needles for injecting drugs. It is estimated that between 2 and 4 million people in the U.S. have hepatitis C.
Hepatitis C is a viral infection that causes inflammation and damages the liver. It usually doesn't go away without treatment and can lead to chronic liver disease, cirrhosis, liver failure, and liver cancer. The inflammation caused by the virus slowly damages the liver over many years, resulting in scarring that interferes with its functioning. This scarring, known as cirrhosis, can lead to chronic liver failure and increase the risk of other complications.
While some people may exhibit symptoms such as abdominal pain, clay-colored or gray stools, and fatigue, many can have hepatitis C for years without any signs. Screening tests, including antibody, RNA, and genotype tests, can detect the infection even in the absence of symptoms. Early detection and treatment are crucial in preventing serious liver damage and improving long-term health.
Fortunately, hepatitis C is curable. Effective treatments include antiviral medications such as sofosbuvir and daclatasvir. With proper treatment, many people can be cured of the infection and live healthy lives. Lifestyle changes, such as avoiding alcohol and maintaining a healthy weight, are also recommended for those with hepatitis C.

It is transmitted through contact with infected blood
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). It is transmitted through contact with infected blood. The virus can remain infectious outside the body for up to six weeks.
The most common cause of hepatitis C transmission is through sharing needles to inject intravenous drugs. It can also be transmitted through sexual intercourse, but this is rare, especially among monogamous couples. The CDC does not recommend the use of condoms for monogamous couples. However, the use of condoms is advised for individuals with HIV or multiple partners.
Hepatitis C can also be transmitted through mother-to-child transfer at birth, contaminated needles used for tattoos or body piercings, and sharing personal items like razors, toothbrushes, or nail clippers that may have come into contact with infected blood. Healthcare workers are also at risk of contracting hepatitis C through needle sticks, sharps, or mucosal exposures to HCV-positive blood.
It is important to note that hepatitis C is contagious even if the infected individual does not show any symptoms or is unaware of their infection. However, it is important to emphasise that hepatitis C is only transmitted through blood and not through other bodily fluids or casual contact.

It can cause acute and chronic liver inflammation and damage
Hepatitis C is a liver disease caused by the HCV virus. It can be contracted through contact with infected blood, such as by sharing needles to inject intravenous drugs. Notably, hepatitis C is contagious even in the absence of symptoms or knowledge of having the infection.
Hepatitis C can cause both acute and chronic liver inflammation and damage. Acute hepatitis is an immediate and temporary response to injury or toxicity in the liver. It is the liver's attempt to purge infections and initiate the healing process. However, if the injury or toxicity persists, so does the inflammation, leading to chronic hepatitis.
Chronic hepatitis C infection refers to long-term, ongoing inflammation in the liver. This persistent inflammation triggers a hyperactive healing response in the liver, resulting in scarring (fibrosis). Over time, the scarring progresses and interferes with the liver's functioning, leading to cirrhosis. Cirrhosis is characterised by permanent scarring that replaces healthy liver tissue, impairing its function.
As cirrhosis advances, it can lead to chronic liver failure, which is the end stage of the disease. Liver failure occurs when the liver can no longer function adequately to meet the body's needs. This condition is fatal without a liver transplant. Chronic hepatitis C can also increase the risk of developing primary liver cancer (hepatocellular carcinoma).

Hepatitis C can lead to cirrhosis, liver failure, and cancer
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). It is a viral infection that causes inflammation and slowly damages the liver over time. You may not experience any symptoms for years, but the infection could be actively harming your liver. The most common cause of hepatitis C transmission in the US is through sharing needles to inject intravenous drugs.
Cirrhosis is a late stage of liver disease, and once it occurs, the liver will not recover. It brings the risk of further complications, including liver failure and liver cancer. Liver failure can be chronic or acute, and liver cancer is also known as hepatocellular carcinoma. Treatment for cirrhosis and its complications may involve cancer therapies such as radiation or chemotherapy, or a complete liver transplant.
While hepatitis C can be cured with medication, prompt treatment after diagnosis is necessary to prevent liver damage, cirrhosis, and liver cancer.

Treatment with antiviral medications can cure most cases
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). The virus causes inflammation that slowly damages the liver over time, leading to cirrhosis, liver failure, and liver cancer. It is usually transmitted through contact with infected blood, such as from unsafe injection practices, unsafe healthcare, unscreened blood transfusions, injection drug use, and sexual practices involving blood exposure.
While some people may clear the virus without treatment, most will develop a chronic HCV infection. Left untreated, the virus continuously replicates in the liver, spreading through the bloodstream. Antiviral medications are the primary treatment option for hepatitis C, and they work by inhibiting the virus's ability to reproduce, thereby reducing its presence in the blood.
Direct-acting antiviral (DAA) medications are highly effective in treating hepatitis C, curing more than 90% of patients. These medications are typically taken orally as tablets or pills once daily for 8 to 12 weeks, although treatment duration may vary depending on the patient's specific needs. The treatment success is determined by achieving a Sustained Virologic Response (SVR), where the virus remains undetectable in the blood 12 weeks after the end of treatment.
The most commonly used DAA medications are sofosbuvir and daclatasvir, which are effective and affordable, especially in low- and middle-income countries. Other antiviral treatments are also available, providing multiple options for patients. These newer antiviral medications have minimal side effects, and lifestyle changes, such as avoiding alcohol and maintaining a healthy weight, can further improve health outcomes.
In summary, antiviral medications offer a highly successful cure for hepatitis C, preventing long-term liver damage and improving patients' overall health and quality of life. Early detection and treatment are crucial to achieving successful outcomes and preventing the progression of liver disease.
