Parvovirus B19 infection is extremely common. Seropositivity rates are 5-10% among young children (aged 2-5 years), increasing to 50% by age 15 years and 60% by age 30 years. A small percentage of adults acquire infection every year, resulting in an incidence of approximately 90% in adults older than 60 years. [8, 6] The annual seroconversion rate among pregnant women without parvovirus B19 is 1.5%. [9]
