Pregnant women may be at greater risk of complications from infection with the novel influenza A(H1N1) virus that is currently circulating, and those who have confirmed or suspected cases of the infection should be treated with antiviral drugs, recommends the US Centers for Disease Control and Prevention (CDC).
The CDC said that evidence from seasonal influenza and from past influenza outbreaks suggests that women who are pregnant may be at greater risk of more severe complications or adverse pregnancy outcomes. As of May 12, the CDC had documented 20 cases of novel influenza A(H1N1) infections in pregnant women, some involving serious complications, including 1 death.
