Abstract

We studied a chamois population affected by an epidemic of sarcoptic mange in Asturias in the North West of Spain in 1991-2002. The study area was 813 km² and population was estimated at 6200 individuals before the epidemic. In 2002 the number of chamois are 2200. The front line of the epidemic has advanced between 1.6 and 7.6 km year. The number of animals showing apparent clinical signs in relation to the number of recorded animals (prevalence) is highest in spring and lowest in summer and autumn. The disease affects more the adult males than to the other groups of sex and age, so the sex ratio has moved towards the females. The relation between the females and kids in July did not change.
