How is the evolution of levels of Igs and HAV in feces and blood?

Viremia occurs after 1-2 weeks of exposure, persists through a period of elevated liver enzymes (ALT). Humoral response occurs prior to symptom onset, IgM detectable before symptoms in about 3-6 months and then decline, and as soon as IgM decline IgG persist after 1 year of exposure to stay lifelong.
