Pregnant women are one of the major risk groups for disease related morbidity and mortality from influenza A (H1N1, swine flu) pandemic. Healthy pregnant women are supposed to have 4 to 5 fold increased rate of serious illness and hospitalization compared to non-pregnant subjects. Herein, the clinical course of novel influenza A (H1N1) infection in two pregnant women was presented. One woman expired due to delay in treatment, while the other one was discharged on day six after prompt treatment. We would like to emphasize that obstetricians should be aware of the clinical and radiological manifestations of influenza A for prompt diagnosis and treatment. Obstetricians also should prepare themselves to provide adequate care for pregnancy related complications encountered by pregnant women with H1N1 infection.
