Control measures taken included movement control inside the country, screening, zoning, surveillance within and outside the protention zone, destruction of animal products, disinfection, vaccination and disposal of carcasses, byproducts and waste.

OIE stated that it will submit follow-up reports on the Newcastle disease situation in Bulgaria until it is resolved.

Bulgaria is just one of several countries that are dealing with Newcastle disease. According to the OIE, Israel has had seven outbreaks of the disease in recent months, affecting as many as 19,400 birds. The Philippines is also struggling with Newcastle disease, as the country’s Department of Agriculture is urging poultry owners to vaccinate their flocks amid the deaths of 41,000 birds.
