Answer

Children with erythema infectiosum are not infectious and may attend child care or school.

Pregnant women in contact with patients in the incubation period of erythema infectiosum or with aplastic crisis have a relatively low potential risk of infection. They can be referred for obstetric follow-up care for possible serologic testing and close fetal monitoring.

Routine exclusion of pregnant women from the workplace where erythema infectiosum is occurring is not recommended, due to the high prevalence of human PV-B19 infection and low incidence of fetal effects.
