Nigeria

Equine Influenza (EI)

On 20 February 2019, ProMED reported further information on an outbreak of EI in Nigeria that was first reported by OIE in January 2019 (ICC Jan 19 #05). There are now more than 3000 equines infected, with reports from the World Organisation for Animal Health (OIE) suggesting the outbreak is a symptom of the unregulated global movement and trading of donkeys for their skins.

 

International animal welfare charity The Donkey Sanctuary has warned of a potential disease epidemic in West Africa, following reports from partners in neighbouring countries Mali and Ghana of donkeys showing similar characteristics of the disease, including fever and nasal discharge. As a member of the OIE’s consultative group International Coalition for Working Equids, The Donkey Sanctuary is taking steps to alert at-risk countries of the threats of an equine influenza epidemic and to offer support to governments and donkey-owning communities to help with the situation, including distributing critical information to communities on how to prevent further spread of the disease. At the same time, the charity is imploring the at-risk countries to immediately prohibit movement of donkeys along trade routes and to tackle illegal movements. With regards to the wider trading of donkeys for their skins, The Donkey Sanctuary believes the biosecurity threats and risk of disease spread are also heightened in such an unregulated and global trade — both in live animals and skin products. It believes the trade must halt until there is evidence to demonstrate that the trade is humane, sustainable and free from the risk of the spread of disease.
