May warrant extended blood safety precautions in hepatitis A; leaves open validation of transmission risk in prospective cohorts.
Observational (n=241)
Viraemia in hepatitis A infection lasts for many weeks, persisting for an average of 60 days after clinical onset.
Costa‐Mattioli et al. (2002) conducted an observational in Hepatitis A infection (n=241). Hepatitis A infection vs. Healthy blood donors was evaluated on Duration and quantification of viraemia. In patients with hepatitis A infection, viraemia persisted for an average of 60 days after clinical onset, with mean viral loads of 6.38 x 10(5) copies/mL on the first day of diagnosis.
