Pandemic 2009 Influenza A(H1N1) Virus Illness Among Pregnant Women in the United States

Abstract

Pregnant women had a disproportionately high risk of mortality due to 2009 influenza A(H1N1). Among pregnant women with 2009 influenza A(H1N1) influenza reported to the CDC, early antiviral treatment appeared to be associated with fewer admissions to an ICU and fewer deaths.
