Hepatitis C: Symptoms

Hepatitis C is a viral infection that affects the liver. It is caused by the hepatitis C virus (HCV) and can lead to short-term or chronic liver disease. Many people have no symptoms for years, so testing is important for early diagnosis. The good news is that modern treatments can cure most people with hepatitis C.

What Is Hepatitis C?

Hepatitis C occurs when HCV infects the liver. Some people clear the virus naturally, but most people who develop an infection can develop chronic hepatitis C. Without treatment, chronic infection may cause liver scarring, cirrhosis, or liver cancer over time.

Unlike hepatitis A and hepatitis B, there is currently no effective vaccine for hepatitis C. However, effective antiviral medicines are available.

How Does Hepatitis C Spread?

Hepatitis C is mainly transmitted through contact with infected blood. Common routes include:

Sharing needles or syringes
Unsafe medical injections or procedures
Receiving unscreened blood or blood products
Sharing equipment that may contain blood
Less commonly, sexual contact involving blood exposure
Transmission from an infected mother to her baby

Hepatitis C is not spread through hugging, kissing, sharing food or drinks, breast milk, or casual contact.

Hepatitis C Symptoms

Many people with hepatitis C have no symptoms. When symptoms occur, they may include:

Fatigue
Fever
Loss of appetite
Nausea or vomiting
Abdominal pain
Dark urine
Pale stools
Joint pain
Yellow skin or eyes, known as jaundice

Because symptoms may be absent, a person can have hepatitis C without knowing it. Testing is the only reliable way to determine whether someone has an infection.

How Is Hepatitis C Diagnosed?

Doctors usually diagnose hepatitis C in two steps. First, an HCV antibody blood test checks whether a person has been exposed to the virus. If the result is positive, an HCV RNA test is used to determine whether the virus is currently present.

A positive antibody test does not always mean an active infection because some people naturally clear the virus.

Hepatitis C Treatment

The treatment of hepatitis C has improved significantly. Direct-acting antiviral (DAA) medicines can cure more than 95% of people with hepatitis C when appropriately prescribed. Treatment is usually taken orally for a relatively short period, depending on the person’s health and liver condition.

People diagnosed with hepatitis C should consult a qualified healthcare professional to determine the appropriate treatment.

How Can Hepatitis C Be Prevented?

There is no hepatitis C vaccine, so prevention focuses on avoiding infected blood. Safe practices include using sterile medical equipment, ensuring donated blood is properly screened, avoiding shared needles, and using appropriate protection during sexual activity when blood exposure is possible.

Hepatitis C can be a serious liver infection, but it is preventable, detectable, and curable. Since many people do not develop noticeable symptoms, appropriate testing can help identify infection early. If you think you may have been exposed to HCV, speak with a healthcare professional about testing.
