Background
More than 45 cases of transfusion‐transmitted hepatitis E virus infection (TT‐HEV) have been reported in Japan. Therefore, in 2020, universal individual donation nucleic acid amplification testing (ID‐NAT) was implemented for HEV.
Study Design and Methods
We characterized HEV NAT‐positive blood donors. The number of new HEV infections and the asymptomatic infection rate were estimated...
Background
In Japan, 41 million blood donations have been screened for hepatitis B virus (HBV) during the past 8.4 years using individual donation nucleic acid amplification testing (ID‐NAT) and antibody to hepatitis B core antigen (anti‐HBc) screening.
Study Design and Methods
Transfusion‐transmitted HBV infection (TT‐HBV) incidence was examined. Donated blood implicated in TT‐HBV was analyzed...
