Prevention and management of influenza in pregnancy.

Influenza infections are an important global source of morbidity and mortality. Pregnant and postpartum women are at increased risk for serious disease, related complications, and death from influenza infection. This increased risk is thought to be mostly caused by the altered physiologic and immunologic specifics of pregnancy. The morbidity of influenza infection during pregnancy is compounded by the potential for adverse obstetric, fetal, and neonatal outcomes. Importantly, influenza vaccination to prevent or minimize the severity of influenza infection during pregnancy (and the neonatal period) is recommended for all women who are or will be pregnant during influenza season.
