Bird flu experts from U.N. agencies are in Nigeria to assist in efforts to contain the lethal strain of the virus.
Officials from the World Health Organization and Food and Agriculture Organization have joined local authorities to inform farmers and others about the potential risks.
A highly pathogenic version of the H5N1 strain was recently discovered in birds on a farm in the northern state of Kaduna. The case was the first of the lethal strain of bird flu reported on the African continent.
Health officials are awaiting test results from two children in Kaduna who recently became sick to determine if they are Africa's first human cases of bird flu.
