Answer

Parvovirus B19 infection is common in school-aged and younger children who attend daycare facilities. In general, children transmit the virus to parents and siblings. In young children, the antibody seroprevalence ranges from 5-10%. This increases to 50% in adolescents and approaches 90% in the elderly. [9, 2]
