Over 95% of fetal complications (fetal hydrops and death) occur within 12 weeks following acute parvovirus B19 (B19) infection in pregnancy. Therefore, weekly fetal ultrasound monitoring is generally recommended for this time period. However, in the majority of women, typical symptoms of acute infection (rash or arthropathy) are absent, and during epidemics, B19 infection may be diagnosed incidentally by antibody screening of women at risk.
