Key result

Surveillance of live bird markets in Bangladesh revealed the complete replacement of HPAI H5N1 clade 2.2.2 by clade 2.3.2.1 and the emergence of reassortant H5N1 lineages carrying genes from H9N2.

Implication

Continued market surveillance is warranted; leaves open the zoonotic and evolutionary implications of these reassortants.

P
Population
Live birds sampled from live bird markets in Bangladesh for avian influenza surveillance between 2011 and 2014.
O
Outcome
Viral evolution and reassortment of H5N1 and H9N2 influenza viruses

The emergence of reassortant HPAI H5N1 lineage in Bangladesh live bird markets poses a continuing threat to poultry and humans.

Cite This Study

Marinova‐Petkova et al. (2016) conducted an observational in Avian influenza (H5N1 and H9N2). Avian influenza surveillance was evaluated on Viral clade replacement and reassortment. Surveillance of live bird markets in Bangladesh revealed the complete replacement of HPAI H5N1 clade 2.2.2 by clade 2.3.2.1 and the emergence of reassortant H5N1 lineages carrying genes from H9N2.
