Figure 3From: High prevalence of antibodies against polyomavirus WU, polyomavirus KI, and human bocavirus in German blood donors Age distribution of virus-specific IgG antibodies. The seroprevalence for WUPyV and HBoV did not differ significantly between age groups (p = 0.855 and p = 0.175, respectively). For KIPyV, a significant rise of seroprevalence rates was observed with increasing age (p = 0.026).Back to article page
