Ghana calls for urgent meeting to control avian flu
afrol News, 14 August - Ghana is seeking a meeting with its western African neighbours to discuss a common measure to prevent incursions of Avian Influenza. A call follows reports on an outbreak of bird flu in Nigeria's remote states of Katsina and Kano last month.
Acting Director of Veterinary Directorate, Dr Enoch Koney said he has called on Togo and Benin, further saying a similar meeting is also planned for Cote d'Ivoire and Burkina Faso.

He said having realised dangers of bird flu the Directorate had notified all regional directors of agriculture as well as veterinary officers about the new cases in Nigeria.

Dr Koney urged stakeholders to have constant check at all live bird markets and monitor staging posts of migratory wild birds at wetlands while they strictly enforced import permits for poultry and poultry products.

Douglas Akrofi Asiedu, co-ordinator, National Disaster Management Organisation (NADMO), said the outbreak of the avian influenza was a real threat to the whole world, especially their region.

He stressed the need for the nation to commit resources to educate and sensitise public on its prevention and how to manage it if it does occur.

United Nations Food and Agriculture Organisation (FAO) said strain of avian influenza recently found in Nigeria was genetically different from strains in previous African outbreaks in Nigeria in 2006 and 2007.

It pointed to other avenues for the virus to have emerged in Nigeria, such as international trade or illegal and unreported movement of poultry. "This increases the risk of an avian influenza spread to other countries in Western Africa," said FAO in a statement.

The virus which is said to rarely infect people, has killed 243 out of 385 known to have been infected since 2003, according to World Health Organisation, while it has also killed or forced slaughter of 300 million birds.

[In many ways, it is useful epidemiologically to look at parts of West
Africa, particularly the stretch along the coast from Ghana to Nigeria, as
being a quasi catchment area for certain animal diseases. Avian influenza
certainly falls into this category because of the traffic in people and
animals crossing the border between Ghana and Togo or Nigeria and Benin.

In fact, there were 4 recent outbreaks in Nigeria (Gombe, Kebbe, Kano,
Katsina), and it is important to intensively follow up this Benin outbreak
in a comparative fashion to see whether there is a common risk factor for
the reintroduction of avian influenza after months of no disease reports.
It is important to establish whether there is new virus circulation, since
the disease was reported on 4 farms last year in November and December 2007.

In Togo, there was one outbreak in June 2007, and there were 2 in July
2007. In Ghana, there were 2 outbreaks in April, 3 in May and one in June
2007. Of course, there were several outbreak farms in Nigeria in the summer
of 2007. Given that now we have cases in both Nigeria and Benin in July and
August 2008, it will be interesting if sampling in Ghana and Togo turn any
positives up during this period, if indeed such important and needed
surveillance is currently being conducted.

H5 Spread to Benin
Recombinomics Commentary 12:47
August 27, 2008

Live chickens purchased at the market in Lokossa as part of the routine surveillance and of the training of managers and other laboratory officials on biomolecular techniques at the Veterinary Laboratory of Parakou.

Causal agent Highly pathogenic avian influenza virus Serotype H5

The above comments from the Benin OIE report describe two chickens that are H5 PCR positive. It is likely that the birds were infected with H5N1 clade 2.2.3 Uvs Lake strain recently reported at multiple locations in northern Nigeria (see satellite map). These outbreaks have a striking parallel with outbreaks in Europe a year earlier.

In June of 2007, a presentation at the Options VI meeting on influenza declared wild birds in Europe to be H5N1 free, based on live bird surveys by various bird conservation groups. These assays, especially when screening fecal samples or cloacal swabs have a notoriously poor record, beginning with testing of wild birds at Erhel Lake in Mongolia in 2005 by these same groups. In the summer of 2005 dead wild birds at the lake were positive for H5N1 clade 2.2, but the testing of live birds at the lake failed to find any H5N1 positives. H5N1 subsequently migrated to the south and west, spreading clade 2.2 into over 50 countries west of China.

Included in this spread were multiple countries throughout Europe, which were H5N1 positive in early 2006. However, the frequency of positives markedly decline in late 2006 and early 2007, which led to the announcement at the talk. However, within minutes of the conclusion of the talk, the Czech Republic reported H5N1 at a poultry farm, which was quickly followed by reports of H5N1 in dead wild birds at multiple locations in Germany, as well as neighboring countries of the Czech Republic and France. The H5N1 was the Uvs Lake strain of clade 2.2.3, which had not been previously reported in Europe. The strain was initially found at Uvs Lake in Mongolia and adjacent locations in Tyva, Russia in the summer of 2006. In the fall of 2006, the strain was found in South Korea and Japan, followed by outbreaks in early 2007 in Kuwait. After the reports of Uvs Lake clade 2.2.3 in the summer of 2007 in Europe, it then became the dominant strain throughout Europe in late 2007 and early 2008.

Last month the Uvs Lake was reported for the first time in Africa, when H5N1 was detected at multiple locations in northern Nigeria. It is likely that the H5 positive poultry in southern Benin is also the Uvs Lake strain of clade 2.2.3.
