An outbreak of H5N1 bird flu on Nigerian poultry farms had spread to four more states, raising the total of affected areas to 11, Agriculture and Rural Development Minister Akinwumi Adesina said yesterday.
Nigeria was the first country on the continent to detect bird flu in 2006 when chicken farms were found to have the H5N1 strain. Nigeria recorded its first human death from the disease the following year.
The latest bird flu outbreak was first reported in mid-January in the states of Kano and Lagos.
The worst- hit state is Kano in the north where 136 905 birds were exposed with a 13% mortality rate.
