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.

Abstract: In March 2011, a multidisciplinary team investigated 2 human cases of highly pathogenic avian influenza A(H5N1) virus infection, detected through population-based active surveillance for influenza in Bangladesh, to assess transmission and contain further spread. We collected clinical and exposure history of the case patients and monitored persons coming within 1 m of a case patient during their infectious period. Nasopharyngeal wash specimens from case patients and contacts were tested with real-time reverse-transcription polymerase chain reaction, and virus culture and isolates were characterized. Serum s les were tested with microneutralization and hemagglutination inhibition assays. We tested poultry, wild bird, and environmental s les from case patient households and surrounding areas for influenza viruses. Two previously healthy case patients, aged 13 and 31 months, had influenzalike illness and fully recovered. They had contact with poultry 7 and 10 days before illness onset, respectively. None of their 57 contacts were subsequently ill. Clade 2.2.2.1 highly pathogenic avian influenza H5N1 viruses were isolated from the case patients and from chicken fecal s les collected at the live bird markets near the patients' dwellings. Identification of H5N1 cases through population-based surveillance suggests possible additional undetected cases throughout Bangladesh and highlights the importance of surveillance for mild respiratory illness among populations frequently exposed to infected poultry.

Abstract: Introduction: Highly pathogenic avian influenza (H5N1) virus (known as "bird flu") is an important public health concern due to its potential to infect humans and cause a human pandemic. Bangladesh is a high-risk country for an influenza pandemic because of its dense human population, widespread backyard poultry raising, and endemic H5N1 infection in poultry. Understanding poultry raisers' perceived risks and identifying their risk exposures can help to develop interventions to reduce the risk of avian influenza transmission. This paper explores the perception of Bangladeshi backyard poultry raisers regarding poultry sickness and zoonotic disease transmission and relevant practices. Methodology: We conducted a qualitative study using social mapping (n=2), in-depth interviews (n=40), household mapping (n=40) and observation (n=16), in two backyard poultry-raising communities. Results: The poultry raisers recognized various signs of poultry illness but they did not distinguish among diseases using biomedical classifications. They perceived disease transmission from poultry to poultry, but not from poultry to humans. They usually kept sick poultry under the bed. If the poultry did not recover, they were slaughtered and consumed or sold. The poultry raisers had close contact with sick birds while handling and slaughtering poultry. Conclusions: The poultry raisers are unlikely to follow instructions from health authorities to prevent "bird flu" transmission because many of the instructions ask low-income producers to change their existing practices and require time, money, and financial loss. Villagers are more likely to comply with interventions that help to protect their flocks and address their financial interest.
