Control and prevention of emerging parasitic zoonoses

Emerging zoonoses have been defined as zoonoses that are newly recognised or newly evolved, or that have occurred previously but show an increase in incidence or expansion in geographical, host or vector range. Among parasitic zoonoses, protozoa are particularly likely to emerge. Control and prevention of emerging parasitic zoonoses are complex tasks that require an integrative and multidisciplinary approach. Reduction of parasite burden is certainly a major objective but cannot be set alone. Therefore, environmental and ecological modifications need to be implemented to reduce not only the parasitic load, but also the risk of parasite transmission. Finally, education and behavioral changes are critical for the success of both control and prevention of these diseases. However, without appropriate financial resources specifically allocated at the local and national levels as well as through international cooperation, control and prevention of these emerging parasitic diseases will not be possible.
