Avian influenza virus (AIV) remains a huge challenge for poultry production with negative repercussions for micro-and macro-economy and public health in Bangladesh. High (HP) H5N1 and low pathogenicity (LP) H9N2 AIV are currently endemic in poultry, and both have been reported to infect humans sporadically. Multiple virus introductions of different clades of HPAIV H5N1, reassorted genotypes, and on-going diversification of LPAIV H9N2 create a highly volatile virological environment which potentially implicates increased virulence, adaptation to new host species, and subsequent zoonotic transmission. Allotropy of poultry rearing systems and supply chains further increases the risk of virus spreading, which leads to human exposure and fosters the emergence of new potentially pre-pandemic virus strains. Here, we review the epidemiology, focusing on (i) risk factors for virus spreading, (ii) viral genetic evolution, and (iii) options for AIV control in Bangladesh. It is concluded that improved control strategies would profit from the integration of various intervention tools, including effective vaccination, enhanced biosecurity practice, and improved awareness of producers and traders, although widespread household poultry rearing significantly interferes with any such strategies. Nevertheless, continuous surveillance associated with rapid diagnosis and thorough virus characterization is the basis of such strategies.

To focus on specific poultry rearing and trading habits in the country and examine their potential impact as risk factors for virus spread and zoonotic transmission.

Geographical and Ecological Frameworks: Bangladesh is a low to a middle-income country in South Asia agriculturally characterized by rich water environments, paddy rice farming, and poultry production. The economy is heavily dependent on agriculture and livestock production. The country consists of a broad, deltaic plain with many tributaries and a sea coast with an extensive mangrove belt. It is at high risk of frequent flooding by three major rivers, the Ganges, Jamuna, and the Brahmaputra. In addition, there is annual flooding from the seaside due to cyclones in the Bengal Bay of the Indian Ocean. Bangladesh is also an attractive and important wintering site for wild migratory birds, in particular, of the order Anseriformes, which breed in arctic and palearctic regions of Russia. Moreover, two major migratory bird flyways, the Central Asian and East Asian-Australian, are crossing Bangladesh. The abundance of shallow coastal wetlands and vast inland wetlands (so-called haors) provide a large reservoir for wildlife, especially waterfowl, which migrate from many parts of Russia and Central Asia during winter. This creates an ecological scenario where wild aquatic birds, domestic ducks and galliform poultry intermingle and in which pathogens, like AIV, can be easily exchanged. Poultry Rearing Systems and Trading Chains: Poultry rearing in Bangladesh comprises commercial and backyard poultry production.Commercial farming can be further categorized according to farm sizes following the sectoring approach of the Food and Agriculture Organization of the United States (FAO) [38]: large-scale breeder farming, medium size farming (broiler, layer, and duck), and small size farming (layer, broiler, quail, pigeon, turkey, guinea fowl, etc.). In Bangladesh, more than 60% of the people live in rural villages, and it is estimated that about 90% of the rural households raise poultry (chicken, duck, pigeon) in traditional backyard settings. Virus Transmission and Risk Factors: Droplet, aerosol, faeco-oral, and direct or indirect contact with contaminated materials are widely described modes of transmission of AIVs [54]. Transmission risks increase depending on host susceptibility and viral load in the environment, as well as on distance between and frequency of contacts. In Bangladesh, the domestic duck is currently considered as the most important epidemiological factor associated with AIV transmission between wild birds and other poultry. Overview of AIV Sub- and Pathotypes in Bangladesh: Viral nucleotide sequences of AIVs detected in Bangladesh were retrieved from public sequence databases (GenBank at National Center for Biotechnology Information (NCBI) or EpiFlu of the Global Initiative on Sharing Avian Influenza Data (GISAID) or Influenza Research Database (IRD)). Until December 2019, a total of 582 fully sequenced avian origin AIV isolates were available. About 79% of these were obtained from domestic birds (n = 462 HA, 461 NA), 14% from environmental samples (n = 84 HA, 83 NA) and 6% from wild birds (n = 36 HA, 35 NA), Supplemental. Although a wide variation of different subtypes was described, HPAIV H5N1 and LPAIV H9N2 constitute the dominant circulating subtypes in poultry and are endemic in the country. HPAI Virases: In the 21st century, HPAI viruses eventfully affected domestic poultry with significant public health and economic concerns throughout South East Asia. In particular, the H5N1 HPAI viruses of the gs/GD lineage, soon after its emergence in Guangdong, China, have become endemically established in domestic poultry across Asia and Africa or have caused excessive epidemics throughout Europe and in North America.

Co-circulation of zoonotic and endemic HPAI H5N1 and LPAI H9N2 viruses in poultry, the recent emergence of a new strain of HPAIV (H5N6) in domestic birds, and the sporadic identification of various other AIV subtypes in poultry and wild bird populations have created a complicated epidemiological situation in Bangladesh. The Bangladeshi H5N1 and H9N2 viruses have evolved into various divergent clusters. Although there currently seems to be a declining trend of HPAI H5N1, this may well be due to a lack of actual disease reporting at farm level and requires virologically convincing evidence. Expansive circulation of non-notifiable H9N2 throughout the whole country currently bears great economic damage to poultry production. Intensified surveillance is at the basis of all efforts to improve AIV-targeted disease control in the country. Public education towards improved awareness and biosecurity is a lengthy process and not expected to yield rapid success. Cost-effective and sensible implementation of avian influenza vaccinations would greatly benefit from well-planned concerted actions of GoB and stakeholders and also does essentially involve collateral virological and serological monitoring of vaccinated flocks. Geographical constraints and the dynamics of the human population in Bangladesh pose severe obstacles to the implementation of improved control measures.
