My purpose is to estimate the relative incidence of various maternal infections associated with fetal death, and to discuss the possible utilization of such information to improve the routine care of pregnant patients in the prenatal clinic. This report of our experience at Stanford is probably a fair presentation of what is being done in the average women's clinic to reduce fetal mortality. Also, as in similar institutions, our work is restricted and in many phases incomplete, owing to an inadequate budget. About 1,000 new patients are treated each year in the Stanford Women's Clinic, with a total annual attendance that varies from 6,000 to 8,000 visits. The pregnant patients are segregated and given special care in the prenatal clinic. The clinic cooperates not only with the routine and special laboratories of the medical school, and with special departments, such as roentgenray and hydrotherapy, but also with the social service
