A condition which can scarcely be considered as a complication of influenza, but which, however, was a large factor in increasing the mortality among women, was pregnancy. Among the cases included in this study were five pregnant women, who came to the hospital and were referred to the medical service. As soon as a complication relative to the existing pregnancy arose they were referred to the Obstetrical Department. On account of the great amount of work in caring for the influenzal patients, and on account of the scarcity of physicians and nurses, we were unable to follow these cases closely enough to give any such definite data as we wish. Three miscarried or went into premature labor. Happily only one of them died. The two which did not miscarry recovered and left the hospital well.

We very soon recognized in consultation with the obstetricians that the pregnant woman was in a really dangerous condition if she contracted influenza. She was likely to have a termination of her pregnancy in the height of the infection, no matter how recent or how remote pregnancy had taken place. If pregnancy did not terminate, the chances of recovery were less than those of the non-pregnant woman; if it did terminate, the chances for recovery were still less. To the pregnant woman with pneumonia very little hope of recovery could be offered. I am indebted to Dr. Paul Titus, of the Obstetrical Department of the School of Medicine, University of Pittsburgh, for a report which includes the cases seen by himself and his assistant, Dr. J. M. Jamison, during this epidemic. Dr. Titus was kind enough to include in his report certain conclusions which merit consideration. The report is as follows: “A series of 50 cases, at all stages of gestation. Interruption of pregnancy occurred in 21, or 42 per cent., of the cases; 29, or 58 per cent., in which pregnancy was uninterrupted. Mortality of pregnant women developing epidemic influenza is higher than that of ordinary individuals, even though their pregnancy is undisturbed, since 14 of the 29 in whom pregnancy was not interrupted died, an incidence of 482
