[A comparative analysis of zoonosis and vector surveillance systems]

To investigate zoonosis and vector surveillance systems in major countries, conducted by quarantine, health and environment authorities, and compare the results with the current Japanese systems.

We elaborated a questionnaire for zoonosis and vector surveillance systems regarding target diseases, vectors, period and area of operation, type of surveillance (active and/or positive), and feedback mechanisms which was then mailed to ten countries having strong trade and tourism links with Japan. We visited some authorities for further discussions.

Eight countries which responded answered that all were conducting zoonosis and vector surveillance. Target diseases included those designated by the International Health Regulations and others with a higher priority for control and prevention in the individual countries. The type of surveillance was classified as: regular monitoring of the vector population, active detection of pathogens in vectors during a specific time period of a year, and intensive pathogen characterization when problems occurred.

The significance of zoonosis and vector surveillance was recognized through this investigation, where we found differences in target diseases, and type of operation. The results should be utilized for generation of more useful and efficient surveillance systems in Japan.
