Pregnancy Raises Swine Flu Death Risk

A CDC analysis shows that pregnant women are more likely than the general population to develop severe disease after infection with the pandemic H1N1 swine flu virus. They are four times more likely to be hospitalized, with an unusually high death rate.

Although media reports have focused on deaths among pregnant women with underlying disease, most pregnant women who have died of swine flu were healthy when they caught the pandemic virus.

Even so, the findings do not mean that all pregnant women will suffer severe disease, says study leader Denise J. Jamieson, MD, MPH, an obstetrician-gynecologist at the CDC's Women's Health and Fertility branch.

"Most women who become ill with flu are going to have mild disease just like in the general population," Jamieson tells WebMD. "But it does seem pregnant women are at increased risk of severe illness and death. So the proportion of deaths among pregnant women is larger than you would expect."

The CDC has details on 266 of the 305 U.S. swine flu deaths reported as of July 29. Fifteen of these 266 deaths -- about 6% -- were among pregnant women. Most of the deaths were among women in their third trimester.
