BACKGROUND Seroepidemiological study of parvovirus B19 has not taken place for some 20 years in Japan. To estimate the risk of parvovirus B19 infection in Japan among blood donors and pregnant women in this century, a seroepidemiological survey and statistical modeling of the force of infection were conducted. METHODOLOGY/PRINCIPAL FINDINGS The time- and age-specific seroprevalence data were ...
