Hepatitis C

SymptomatologyThere are two distinctions for infection: acute and chronic. Acute infections last from 15 days to 150 days . Majority of people with acute HCV are asymptomatic, the most prevalent symptom, if any, is fatigue in acute hepatitis. About 80% of acute infections become chronic, which can lead to scarring of the liver. Once the liver is compromised, symptoms include jaundice, dark urine, abdominal pain, loss of appetite and nausea. Over time, in about 70% of chronic infections, the pathogen ultimately leads to cirrhosis of the liver, which is generally apparent after many years. In some cases, those with cirrhosis will go on to develop liver failure, liver cancer or life-threatening esophageal and gastric varices.

1) Virus first gains entry into the host cell by attaching to receptors on the cell membrane. 2) Replication occurs inside the host cell.3) Once inside the cytoplasm of the host cell, the virus loses its capsule to transcribe a complimentary negative strand RNA molecule.
