AI Article Synopsis
- Highly pathogenic avian influenza (HPAI) has been a significant public health issue in Bangladesh since its first poultry outbreak in 2007, with ongoing efforts to monitor and manage the virus.
- The predominant strain in the region is the H5N1 clade 2.3.2.1a, which is mutating over time, indicating a need for continuous surveillance due to its persistent presence in live bird markets.
- Effective control of avian influenza requires a collaborative 'One Health' strategy that involves government action and stakeholder engagement, addressing systemic issues such as weak biosecurity in the poultry sector.
Article Abstract
Highly pathogenic avian influenza (HPAI) has been a public health threat in Bangladesh since the first reported outbreak in poultry in 2007. The country has undertaken numerous efforts to detect, track, and combat avian influenza viruses (AIVs). The predominant genotype of the H5N1 viruses is clade 2.3.2.1a. The persistent changing of clades of the circulating H5N1 strains suggests probable mutations that might have been occurring over time. Surveillance has provided evidence that the virus has persistently prevailed in all sectors and caused discontinuous infections. The presence of AIV in live bird markets has been detected persistently. Weak biosecurity in the poultry sector is linked with resource limitation, low risk perception, and short-term sporadic interventions. Controlling avian influenza necessitates a concerted multi-sector 'One Health' approach that includes the government and key stakeholders.
