Disease incidence among medical personnel in Kazan (according to local insurance company)

Data of insurance companies on the incidence of diseases of the insured, of course, do not give such a complete picture of the state of health of this or that occupational group, which we get during a detailed physical examination. Nevertheless, these data, although schematic and incomplete, reflecting the dynamics of diseases, are, in our opinion, quite valuable subsidiary material for the study of occupational disease incidence. This induced us to work on development of Kazan health care workers' morbidity data, covering the period from 1/Х 1925 to 1/Х 1926. While comparing with morbidity of other groups we used tables of Dr. Pleschitzer from his article "General morbidity of insured in Kazan". Kazan" for the same period.
