- establishment of protection and surveillance zones around the outbreak area,
- restrictions on movements of poultry and on the use of products liable to be contaminated by tightening biosecurity measures at all levels of poultry production,
- post-outbreak active surveillance and monitoring: all villages in the surveillance zones were visited to ensure the detection of any other infected villages, but no positive clinical scenario was found up to date,
- collection of totally 512 swab samples and 1,660 serum samples from 60 villages in continuation of the post-outbreak active surveillance in the surveillance zones around the outbreak area. All the results were negative.
