Although the incidence and fatality of human anthrax has decreased in this country during the past ten years, it still remains one of the chief problems of certain industries. Dr. H. F. Smyth, prominent authority on this subject, expressed the belief that the reduced incidence of anthrax is apparent rather than real, since the last ten years have been years of depression, and consequently there has been a reduced number of employees in the industries which usually account for the cases of human anthrax. Then, too, the information obtained from many states is still incomplete and inadequate. Indeed, the records of one of the states do not distinguish between animal and human anthrax.
The fatality rate for this disease is still high, being more than 16 per cent for the five year period 1934-1938, although this was 6 per cent less than the rate in the preceding five year period.
