The epidemiology of this disease is complex and a thorough understanding is required for the implementation of successful control programmes. Because of this, we wish to reemphasize the most important epidemiological factors, and draw attention to the recent reports and implications of arrested larval development of A. caninum which occurs at the gut level. Until 1973, the major points to be considered in the epidemiology of canine hookworm infections were as follows…
