Abstract

Highly Pathogenic Avian Influenza A(H5N1) Virus in Poultry, Nigeria, 2015.

Highlights

To the Editor: In Nigeria, from February 2006 through July 2008, outbreaks of highly pathogenic avian influenza (HPAI) subtype H5N1 virus infection in poultry negatively affected animal and public health as well as the agricultural sector and trade
In January 2015, seven years after disappearance of the virus, clinical signs of HPAI and increased mortality rates were observed among backyard poultry in Kano and in a live bird market in Lagos State, Nigeria
The samples were adsorbed onto 2 Flinders Technology Associates cards (GE Healthcare Life Sciences, Little Chalfont, UK), which were sent to the World Organisation for Animal Health/Food and Agriculture Organization of the United Nations Reference Laboratory for Avian Influenza in Italy for subtype confirmation and genetic characterization
