In 1996, strategies of fox vaccination were modified and adapted to control a rabies reinfection focus, in the presence of a fox population of a high density. Two aerial vaccinations were carried out during the cold season, the baiting density was increased to a rate of 17 baits per square km and an additional campaign of cubs vaccination was performed by distributing manually about 10-20 baits per breeding den. During this year, rabies was confirmed in 28 foxes, 1 badger, 1 stone marten and 14 domestic animals collected in southern Belgium (provinces of Luxemburg, Namur and Hainaut). As compared with the epidemiological situation observed in 1995, these cases demonstrated a decrease of rabies incidence. Results from both tetracycline (biomarker) and rabies antibodies detection tests showed that protection against rabies was confered to a sufficient fraction of the fox population. Thanks to an adapted strategy of fox vaccination and a good cross-border cooperation, the reinfection rabies focus is almost under control.
