Abstract
Maedi-visna was accidentally introduced into Iceland by importation of a flock of Karakul sheep intended for breeding purposes in the year 1933. A brief description of maedi-visna in Iceland and its eradication is presented. Owing to the insidious onset of maedi the disease was first recognized in 1939 when it already had spread to many flocks in two different parts of the country. In individual flocks the annual mortality rate was often 15–30 per cent. The heavy losses and the wide spread of the disease are thought to be due to the traditional sheep farming practices in Iceland. An eradication program was started in 1944, slaughtering all sheep in affected areas, and replacing them with healthy young sheep from other parts of the country. The eradication was sucessfully accomplished in the year 1965.
