Westward Spread of<i>Echinococcus multilocularis</i>in Foxes, France, 2005–2010

Abstract

During 2005-2010, we investigated Echinococcus multilocularis infection within fox populations in a large area in France. The parasite is much more widely distributed than hitherto thought, spreading west, with a much higher prevalence than previously reported. The parasite also is present in the large conurbation of Paris.
