We describe a rabies epizootic in northwest Alaska (USA) during 1989 a
nd 1990 which resulted in mortality to several different wolf (Canis l
upus) pack. Four radio-collared wolves were confirmed to have rabies w
hile evidence for seven others was strongly suggestive but not con fir
med. The wolf population declined during the rabies epizootic thus rab
ies may have been a significant limiting factor.
