What are the signs and symptoms of acute HCV infection?
Persons with newly acquired HCV infection usually are asymptomatic or have mild symptoms that are unlikely to prompt a visit to a health care professional. When symptoms occur, they can include
Fever
Fatigue
Dark urine
Clay-colored stool
Abdominal pain
Loss of appetite
Nausea
Vomiting
Joint pain
Jaundice
How soon after exposure to HCV do symptoms appear?
In those persons who do develop symptoms, the average time period from exposure to symptom onset is 4–12 weeks (range: 2–24 weeks).
What are the signs and symptoms of chronic HCV infection?
Most persons with chronic HCV infection are asymptomatic. However, many have chronic liver disease, which can range from mild to severe, including cirrhosis and liver cancer. Chronic liver disease in HCV-infected persons is usually insidious, progressing slowly without any signs or symptoms for several decades. In fact, HCV infection is often not recognized until asymptomatic persons are identified as HCV-positive when screened for blood donation or when elevated alanine aminotransferase (ALT, a liver enzyme) levels are detected during routine examinations.
