Summary

  • HAV replicates in a noncytopathic manner, and viremia is declining when symptoms of hepatitis develop
    • This suggests that hepatocellular injury in HAV is immune mediated, with both innate and adaptive immune responses involved
  • Early replication of HAV after infection without significant inflammatory response suggests subversion of the initial innate immune response
