Abstract
During 1997, rabies was confirmed in 5 foxes and 3 cattle collected in
southern Belgium (provinces of Luxemburg and Namur). Six out of these 8
cases occurred during the first trimester. As compared with the
epidemiological situation observed during the previous year (44 cases),
there is a significant decrease of rabies incidence; a consequence of
the strategy of fox vaccination, that was adapted since 1996 to control a
rabies reinfection focus, in the presence of a high density of fox
population. During this year, two aerial vaccinations were carried out
during the cold season, (baiting density: 17 baits per km2) and an
additional campaign of cubs vaccination was performed by distributing
manually about 10-20 baits per breeding den. Results from both
tetracycline (biomarker) and rabies antibodies detection tests showed
that protection against rabies was confered to the fraction of the fox
population that is required for rabies elimination. Thanks to the
modified strategy of fox vaccination and a good cross-border
cooperation, the reinfection rabies focus that occurred in 1994-1995 is
likely to be controlled.
