Abstract
Summary : Serotype O was the only type of FMD virus identified in Sri Lanka during 1977-1981. One epizootic of FMD occurred in 1977-1978 originating in Mullattivu. The cause of the spread was believed to be the transportation of cattle to major towns. The highest incidence of FMD was recorded in the Northern and North-Central Provinces. Selflimiting outbreaks occurred in Kalmunai in 1979 and in Mullattivu in 1979 and 1980. A limited outbreak of FMD was reported at Kekirawa in 1980. By means of an FMD control programme inaugurated recently it has been possible to contain the disease. The success of this pro gramme is reflected in the declining incidence of FMD in the island during 1977-1981. An annual vaccination programme in the enzootic zone is to be extended to the buffer zone in 1982 with the aim of con taining the disease and then eradicating it.
