human parvovirus b19 infection in blood donors.using an immunodiffusion assay, we tested all of the blood units donated at the fukuoka red cross blood center from june 1991 to july 1994 for b19 antigen. over this 3-year trial period, we detected 16 viremic cases out of approximately 560,000 blood donors. interestingly, most of the viremic donors (15 out of 16) were detected between february 1992 and january 1993, which coincided with a local erythema infectiosum epidemic in the fukuoka area (december 1991 to august 1992). in particular, we d ...19958578732
human parvovirus (b19) and erythema outbreak of erythema infectiosum ("fifth disease") was studied in fukuoka, japan, in 1980-1981. human parvovirus (hpv) antigen was not detected in any patients, but anti-hpv, measured by countercurrent immunoelectrophoresis, was found in 33 of 34 affected children and in 21 (15%) of 141 children of the same ages without the disease. immunoglobulin m class anti-hpv was present in all 25 children with erythema infectiosum tested. in a survey of hospital patients, the prevalence of anti-hpv dete ...19852989471
a significant age shift of the human parvovirus b19 antibody prevalence among young adults in japan observed in a decade.a seroepidemiological study on human parvovirus (b19) in japan was undertaken with serum samples randomly collected from healthy japanese populations (416 in 1973, 675 in 1984 and 508 in 1987/88). all samples were tested for anti-b19 igg antibody by the indirect antigen-capture elisa. the antibody prevalence for ages 0-9 years old in 1984 was significantly higher (16%) than that in 1973 (2%), whereas those for ages 20-29 years and 30-39 years were significantly lower in 1984 (20% and 56%) than i ...19921434067
