H5N1 highly pathogenic avian influenza (HPAI) has struck two poultry producing farms in the North Korean capital of Pyongyang, killing more than 46,000 birds, according to a report posted by the World Organization for Animal Health (OIE).
In the first outbreak, all 46,217 birds died of the disease in three holding pens for layer hens on a farm at the Hadang chicken factory. The outbreak began Mar 21. Samples from the birds tested positive on Mar 26.
In the second, an unreported number of chickens died in one ‘cage’ at Sopo chicken factory in the same region on 27 March.
The presence of the H5N1 subtype of the avian flu virus has been confirmed but the source of infection is as yet unknown.
Usual measures have been put in place to control the spread of infection: quarantine, movement control inside the country, screening and disinfection of infected premises/establishment(s).
The last outbreak of HPAI in the country was in May 2013.
