  15. 15. en/Sheep with Sheep pox /NOT SMALLPOX <ul><li>Article below is NOT AN ALERT, we did research and found that it was translated from a Greek article and the term smallpox was used instead of SHEEP POX (an error of the Newspaper). </li></ul><ul><ul><li>Source: ERT Regions: Europe Place Name: Greece </li></ul></ul><ul><ul><li>Sheep with Smallpox </li></ul></ul><ul><ul><li>Smallpox cases have been located in a flock of sheep in Mandamados, Lesvos. The Lesvos Veterinary Department proceeded with the extermination and sanitary burial of the diseased animals. It also imposed the stock farm under ten-kilometre area quarantine. It is likely that the disease originated from the Turkish coast, where it has spread. The authorities have appealed to all stock breeders to report any smallpox cases to the local veterinaries immediately. Stock breeders, whose animals are put to death, are fully compensated. Scientists have ruled out the possibility of people to be infected from the disease. </li></ul></ul><ul><ul><li>Link: </li></ul></ul>
