Summary While swine production is rapidly growing in South-East Asia, the structure of the swine industry and the dynamic of pig movements have not been well-studied. However, this knowledge is a pre-requisite for understanding the dynamic of disease transmission in swine populations and designing cost-effective surveillance strategies for infectious diseases. In this study, we assessed the farming and trading practices in the Vietnamese swine familial farming sector, which accounts for most pigs in Vietnam, and for which disease surveillance is a major challenge. Farmers from two communes of a Red River Delta province (Northern Vietnam) were interviewed, along with traders involved in pig transactions. Major differences in the trade structure were observed between the two communes. One commune had mainly transversal trades, i.e. between farms of equivalent sizes, whereas the other had pyramidal trades, i.e. from larger to smaller farms. Companies and large familial farrow-to-finish farms were likely to act as major sources of disease spread through pig sales, demonstrating their importance for disease control. Familial fattening farms with high pig purchases were at greater risk of disease introduction and should be targeted for disease detection as part of a risk-based surveillance. In contrast, many other familial farms were isolated or weakly connected to the swine trade network limiting their relevance for surveillance activities. However, some of these farms used boar hiring for breeding, increasing the risk of disease spread. Most familial farms were slaughtering pigs at the farm or in small local slaughterhouses, making the surveillance at the slaughterhouse inefficient. In terms of spatial distribution of the trades, the results suggested that Northern provinces were highly connected and showed some connection with Central and Southern provinces. These results are useful to develop risk-based surveillance protocols for disease detection in the swine familial sector, and to make recommendations for disease control.

“…These interactions present opportunities for pathogens and parasites to be re‐introduced resulting in catastrophic revenue and production losses (Cooper et al ). Feral swine pose risks to domestic and commercial herds by introduction of more than eleven previously known parasites and pathogens of domestic swine (Clark et al , New et al , Bengtson and Rogers , Mullen and Durden , Giurgiutiu et al , Meng et al , Smith et al ) including tularemia ( Francisella tularensis McCoy & Chapin) and the African swine fever virus by ixodid and argasid ticks, respectively (Greiner et al , Witmer et al ). Feral swine trapped within 10 km of domestic swine facilities in Texas and fitted with geo‐positioning sensors visited domestic swine pens more frequently than empty control pens (Wyckoff et al ).…”

“…Among wild animals, non-human primates are of particular importance as reservoirs of potential zoonotic pathogens due to their short phylogenetic distance to humans, which compensate for their relatively low density and limited opportunity of contact with humans compared with domestic animals (Greger 2007;Smith et al 2011;Wolfe et al 2007). Rodents have a more distant phylogenetic relationship to humans but have high abundance and density, several species are peri-domestic, and are a reservoir for several re-emerging zoonoses, e.g.…”

The essence of One Health is an interdisciplinary approach combined with some degree of intersectoral integration that is aimed at mitigation of human and animal health risks, taking account of environmental, ecological, social and economic factors. While a large number of international stakeholders now consider the One Health approach necessary for more effective protection of the global community against health threats, there is still no systematic allocation of resources to integrated national or multinational programmes, partly due to the inertia of existing sectoral systems and the lack of convincing economic arguments in support of the approach. We propose different degrees of sectoral integration depending on system types and associated economic efficiency gains to be expected from a One Health approach. International and regional organisations have an important role in facilitating the adoption of the approach, since the costs and the benefits are often of a regional or even a global nature, such as in the case of avian influenza.
