La grippe du porc : situation épidémiologique en France [swine influenza: epidemiological situation in France].
Bulletin de l’Académie Vétérinaire de France, 2004, Volume 157, N°4, 29-34
In France, swine influenza is a source of concern, particularly in Brittany which is the region with the highest pig density. Currently, the H1N1 and H1N2 serotypes are actively circulating while the H3N2 serotype is much less present. Influenza may cause fever, cough, reduced feed intake, reduced average daily weight gain and economic loss. The control of influenza is hampered by the intense movements of animals and the enzootic and epizootic features of the disease. The continuous evolution of influenza viruses, the role of pigs as mixing vessels and the potential interference with avian sources, in particular turkey farms, underline the need for a straight epidemiological surveillance of the disease.
