This report found that,during 2009, 16 pregnant women and one who was postpartum were admitted to New York City intensive-care units (ICUs). Two women died. Of the 17 women, or 12 had no recognized risk factors for severe influenza complications other than pregnancy. All 17 women received antiviral treatment with oseltamivir; however,treatment was initiated ¡Ü2 days after symptom onset in only one woman and was begun ¡Ý5 days after symptom onset in four women. Because initiation of antiviral treatment ¡Ü2 days after onset is associated with better outcomes, pregnant women should be encouraged to seek medical care immediately whether they develop influenza-like symptoms, or health-care providers should initiate empiric antiviral therapy for these women as soon as possible,even whether >2 days after symptom onset.
