<i>Notes from the Field:</i> Human Parvovirus B19 Infections Among Pregnant Persons — Minnesota, January–September 2024
Human parvovirus B19 (B19) commonly causes asymptomatic infection or mild illness in healthy children and nonpregnant adults, but infection during pregnancy can lead to severe perinatal sequelae, particularly when infection occurs before 20 weeks' gestation.In July 2024, the Minnesota Department of Health (MDH) was notified by a maternal-fetal medicine specialist of an increase in B19 infections among pregnant persons associated with fetal complications.Although increased circulation of B19 had not been described in the United States at that time, review of the literature revealed that European surveillance indicated increases in B19 in late 2023 and 2024 identified through laboratory, clinical, and blood donation screening data (1,2).
