Alveolar echinococcosis is one of the most important lethal
zoonotic helminth infections in the northern hemisphere.
Currently, the threat to public health is increasing,
as evidenced by the rising prevalence rate of alveolar echinococcosis,
as well as the invasion of urban areas by infected
wild foxes. This threat is further increased due to
the involvement of pet dogs, and probably cats, as emerging
sources of infection. These increased threats to public
health also have associated economic risks; therefore,
there is a need for effective and sustainable methods of
control. In this paper, initiatives to control alveolar echinococcosis
by targeting its definitive hosts through anthelmintic
baiting campaigns initiated by local residents
who used local resources for bait production, distribution
and collection of fecal samples for diagnosis are described.
Further, when such distribution programs are coupled
with the use of GIS-based maps, the optimum distribution
of bait was obtained. These programs have also included
the use of intravital diagnostic analyses of infection rates,
which have been overseen by the Forum on Environment
and Animals (FEA), and also allowed a nationwide monitoring
of echinococcosis in difinitive hosts. In addition, a
government initiative requiring mandatory reporting of
echinococcosis in dogs to health authorities was recently
initiated in Japan. Overall, the results of this study have
shown that use of collaborative control initiatives targeting
zoonotic agents of alveolar echinococcosis can be an effective
method for reducing the threat of lethal echinococcosis
in the northern hemisphere.
