In the biggest and most detailed look yet at pandemic flu infections in pregnant women, researchers from the US Centers for Disease Control and Prevention (CDC) have reported that early antiviral treatment was linked to fewer intensive care unit (ICU) admissions and that severe illnesses and deaths are more likely to occur during the third trimester.  The CDC researchers, along with a Pandemic H1N1 Influenza in Pregnancy Working Group made up of health officials from several U.S. states, based their findings on reports of pregnant women who were sick with pandemic H1N1 infections through August plus more recent reports of women who were admitted to ICUs.  The findings appear in the Apr 21 issue of the Journal of the American Medical Association (JAMA).  CIDRAP
