Avian influenza dynamics in Bangladesh: past, present and future

Avian influenza viruses (AIV) are significant transboundary zoonotic pathogens that concern both animal and public health. Since the first report in Bangladesh in early 2007, AIVs have resulted in several outbreaks across the country, hindering sustainable growth of the poultry industry through economic losses in different production sectors. HPAI and LPAI are currently co-circulating and continuing infection in poultry sectors in an epidemic manner in Bangladesh as well as in migratory and wild bird species.

HPAI and LPAI are currently co-circulating and continuing infection in poultry sectors in an epidemic manner in Bangladesh as well as in migratory and wild bird species.

The risk of viral transmission at the human-poultry interface is increasing over time due to a lack of surveillance and early detection strategy/practices; inappropriate biosecurity knowledge among the poultry raisers; complex supply chain of the backyard and commercial poultry and live bird market systems.

It is expected that improving AIV surveillance in poultry flocks and live bird market (LBM), vaccination, biosecurity, and awareness among poultry professionals is beneficial to controlling the disease burden in the poultry industries.

The increasing number of human cases in Bangladesh suggests that a One Health approach engaging various stakeholders from the public and private sectors would be a better option for successfully controlling and limiting avian influenza outbreaks in Bangladesh.
