A new report from the U.S. Centers for Disease Control and Prevention examines maternal and infant outcomes among critically ill pregnant and post partum women with 2009 Influenza A (H1N1) infection.
Between April 2009 and August 2010, the CDC received reports of 278 pregnant or postpartum women who were admitted to the ICU and survived and 84 pregnant or postpartum women who died.
Infants born during their mother’s hospitalization for severe influenza illness were more likely to be born preterm and of lower birth weight than the general population. Infants born after their mothers had been discharged were more likely to be small for gestational age and of lower birth weight.
Consistent with previous reports, pregnant women receiving prompt treatment with recommended antiviral medications were less likely to die than those treated later.
According to the CDC, “the potential impact of severe influenza during pregnancy on mother and infant/fetus emphasizes the importance of influenza vaccination of pregnant women, regardless of pregnancy trimester, and the importance of prompt, empiric treatment with appropriate antiviral medications for pregnant women with suspected or confirmed influenza.”
