Affected population A backyard poultry farm consisting of 22-week-old layers, 10-week-old growers and 4-week-old broilers.
The above comments from a January 9 OIE report describe the poultry affected by HPAI H5. The onset date is almost exactly nine years since the H5N1 outbreak in Kano, Nigeria, which was the first reported outbreak in Africa. Nigeria has not reported an H5N1 case since 2008, so the report of high path H5 raises concerns that the outbreak is linked to migratory birds, which are carrying H5N8 in Europe.
Confirmation of H5N8 in Kano would raise the same questions raised in early 2006, which was on surveillance in countries in the Middle East and Africa, which also had not reported any H5N1 cases in 2005. In early 2006 human H5N1 cases were confirmed in Turkey, which was then followed by detection of H5N1 in countries in Europe, the Middle East and Africa.
In 2014, reported H5N8 in Europe has been limited to four countries (Germany, Netherlands, England, and Italy) which once again raises surveillance concerns since the H5N8 has been detected in many wild birds as well as the Rostock zoo, but many neighboring countries have not reported H5N8.
In 2014 H5N8 expanded its reach to the United States and also reassorted with North American wild birds N2 to produce H5N2 with 5 Fujian clade 2.3.4.6 gene segments, including H5 and 3 North American gene segments, including N2.
Confirmation of H5N8 in Nigeria would dramatically extend the global expansion and threaten the poultry industry worldwide.
