The impact of influenza virus infection in pregnancy

Abstract

Data from previous seasonal epidemics and pandemics have confirmed that pregnant women are at increased risk for severe influenza virus infection. Complications including fetal loss, higher rates of hospitalization and maternal death are most notable during the late gestational period. Antiviral therapy and influenza vaccination are recommended in pregnant women as both are effective and safe. This review discusses the epidemiology, pathophysiology, treatment and prevention of influenza virus infection in pregnancy, with a focus on recent developments.
