The typhus epidemic observed at the end of last year and the beginning of this year in Kazan gave me quite a lot of material for studying the influence of this disease on the course of pregnancy and the fetus. Back in 1867, Dr. Kaminsky gave us a diagram of how to monitor fever in the mother, and at the same time accurately established the influence of typhoid fever on the course of pregnancy and the fetus. It was he who pointed out that out of 98 typhoid cases in 63, the pregnancy was terminated, the course of the disease itself during pregnancy was ordinary, and bleeding easily follows after childbirth. Further, Kaminsky found that with a rise in the mother's temperature to 40 , there is a danger for the life of the fetus in the form of a changed heartbeat and its movements, indicating the onset of intrauterine asphyxiation of the fetus. This danger increased as the temperature rose or its status quo continued for a long time, and the case in these cases was resolved either by an interruption of pregnancy or by the death of the fetus without the termination of pregnancy at this time.
