The Perceived Value of Passive Animal Health Surveillance The Case of Highly Pathogenic Avian Influenza in Vietnam
Economic evaluations are critical for the assessment of the efficiency
and sustainability of animal health surveillance systems and the
improvement of their efficiency. Methods identifying and quantifying
costs and benefits incurred by public and private actors of passive
surveillance systems (i.e. actors of veterinary authorities and private
actors who may report clinical signs) are needed. This study presents
the evaluation of perceived costs and benefits of highly pathogenic
avian influenza (HPAI) passive surveillance in Vietnam. Surveys based on
participatory epidemiology methods were conducted in three provinces in
Vietnam to collect data on costs and benefits resulting from the
reporting of HPAI suspicions to veterinary authorities. A quantitative
tool based on stated preference methods and participatory techniques was
developed and applied to assess the non-monetary costs and benefits.
The study showed that poultry farmers are facing several options
regarding the management of HPAI suspicions, besides reporting the
following: treatment, sale or destruction of animals. The option of
reporting was associated with uncertain outcome and transaction costs.
Besides, actors anticipated the release of health information to cause a
drop of markets prices. This cost was relevant at all levels, including
farmers, veterinary authorities and private actors of the upstream
sector (feed, chicks and medicine supply). One benefit associated with
passive surveillance was the intervention of public services to clean
farms and the environment to limit the disease spread. Private actors of
the poultry sector valued information on HPAI suspicions (perceived as a
non-monetary benefit) which was mainly obtained from other private
actors and media.
