2009 Pandemic Influenza A (H1N1) in Pregnant Women Requiring Intensive Care — New York City, 2009
To characterize the severity of 2009 H1N1 virus infection in pregnant women, the New York City Department of Health and Mental Hygiene conducted surveillance for cases in pregnant women requiring intensive care. The findings indicated that, during 2009, 16 pregnant women and one who was postpartum were admitted to intensive-care units. Two women died. Of the 17 women, 12 had no risk factors for severe influenza complications other than pregnancy, and only one woman received antiviral treatment within 2 days of symptom onset.
