Abstract

Fox rabies re-emerged in northeastern Italy in 2008, in an area bordering Slovenia. In 2009, the infection spread westward to Veneto region and in 2010 to the provinces of Trento and Bolzano. Aerial emergency oral fox vaccination was implemented in the winter 2009-10. Since this vaccination was performed at altitudes below the freezing level, a statistical analysis was conducted to evaluate its impact. Of the foxes sampled following the vaccination campaign, 77% showed a rabies antibody titre of >or=0.5 IU/ml.

Highlights

  • In October 2008, rabies infection was diagnosed in a red fox (Vulpes vulpes) in the municipality of Resia (Region of Friuli Venezia Giulia, northeastern Italy) [1]

  • Oral fox vaccination campaigns using SAD B19 vaccine baits [3] were conducted in these areas in 1989 and from 1992 to 2004, and the last documented animal to be infected with rabies was a fox diagnosed in December 1995 in the province of Trieste (Friuli Venezia Giulia), in an area bordering Slovenia

  • The study period ranged from the date that the first case was reported in Veneto region (17 November 2009) to the date of conclusion of the study monitoring the effectiveness of the emergency oral fox vaccination campaign (9 May 2010)

Impact of emergency oral rabies vaccination of foxes in northeastern Italy, 28 December 2009–20 January 2010: preliminary evaluation. Fox rabies re-emerged in northeastern Italy in 2008, in an area bordering Slovenia. Aerial emergency oral fox vaccination was implemented in the winter 200910. Since this vaccination was performed at altitudes below the freezing level, a statistical analysis was conducted to evaluate its impact. Of the foxes sampled following the vaccination campaign, 77% showed a rabies antibody titre of ≥0.5 IU/ml
