5 Must Know Facts For Your Next Test

1. HCV is primarily transmitted through exposure to infectious blood, often via intravenous drug use or transfusions.
2. Direct-acting antivirals (DAAs) are the most effective treatment for HCV, targeting specific steps in the viral life cycle.
3. The immune response to HCV involves both cellular immunity and the production of antibodies against the virus.
4. Chronic Hepatitis C can lead to severe liver damage such as cirrhosis and hepatocellular carcinoma if left untreated.
5. Diagnosis of HCV includes serological tests for antibodies and molecular tests for viral RNA.
