Epidemiological comments An African swine fever outbreak has been reported in free-range pigs from villages at the north-eastern border. Free-range pigs spread the disease before it could be confirmed. The affected areas have been put under quarantine to limit spread of the disease. Two 24 hours veterinary check-points have been mounted along the major roads leaving the Nyakomba and Nyamaropa areas to prevent illegal movement of live pigs and pig products from the affected areas. Disease surveillance currently on-going to determine the extent of spread of infection. Veterinary personnel on the ground, in collaboration with local village leadership and members of the dip tank committee, have started awareness campaigns in the affected villages. Farmers are being instructed to confine their pigs in pigsties and report all ill or dead animals to their local Division of Veterinary Services offices.
