Recent State of Parasitoses in Japan — Epidemiology for clinicians —
نویسنده
چکیده
The recent profile of parasitic diseases in Japan has changed dramatically from public health problems with high community prevalence of classic soil-transmitted parasitoses (ascariasis, hookworm disease, etc) to epidemics of various new types of parasitoses (larva migrans, zoonotic parasitoses, imported parasitoses, opportunistic parasitoses, etc). Against this background of change are factors such as the diversification of lifestyles and dietary habits, recent changes in values including the return-to-nature movement and the pet boom, the globalization of parasitoses due to the development of transportation, and the increase in compromised hosts reflecting the rapid increase in the number of aged citizens. These new types of parasitoses are generally characterized by fragile host-parasite relationships, and disruption of these relationships tends to cause the serious manifestation of parasitoses. They also frequently present difficulties in diagnosis and treatment. As a result, we need to shift emphasis from the public health aspects of these diseases that require conventional mass control to respective clinical interventions requiring individualized care for diversified pathogeneses.
