Identification of agent: highly pathogenic avian influenza virus subtype H5N1.
Date of first confirmation of the event: 7 October 2005.
Date of start of the event: October 2005.
The first outbreak of avian influenza was registered on 7 October 2005 at Ceamurlia-de-Jos in Tulcea county. From 7 October 2005 to 24 April 2006, 53 outbreaks were confirmed at 52 localities in 9 counties in the Danube Delta and Black Sea area: Tulcea, Braila, Buzau, Calarasi, Constanta, Dambovita, Dolj, Ialomita and Ilfov counties. On 21 April 2006, the last outbreak of avian influenza in Romania ended (Deleni village/Constanta county). All outbreaks occurred in small backyard premises and no commercial farms were affected.
There are no other new cases of suspicion or confirmation of avian influenza in Romania.
To control the disease, Romania adopted two different control measures applied in the outbreaks, in accordance with the Romanian legal provisions in force:
- stamping out: 46 outbreaks;
- zoning: 7 outbreaks (3 in Ialomita county and 4 in Calarasi county).
During this period, 421,470 birds from 16,166 backyard premises were destroyed.

Other details/comments:
- The protection and surveillance zones have been established in accordance with European Union legislation (European Commission Decision 2006/115/EC).

All poultry within the zones must be kept inside and all poultry holdings - including hobby holdings - must be registered. The Danish Veterinary and Food Administration will inspect all poultry holdings in the protection zones in order to look for possible further spread of avian influenza. Restrictions on movement of eggs and poultry have been imposed within the zones. All hunting within the zones is also prohibited.
- Several protection and surveillance zones have been lifted since the end of March. Information about removal of zones can be accessed on the Danish Veterinary and Food Administration’s website.
