Abstract:
The current COVID-19 pandemic, which started in Wuhan, China, underscores what the public health community has warned about for more than two decades—the risk of viral diseases capable of spreading from animal to human hosts. The first outbreaks of “bird flu” (highly pathogenic avian influenza—HPAI, subtype H5N1)—raised similar concerns 20 years ago, concerns that have persisted with the outbreak of SARS in 2002–2004 and COVID-19 today. A recent study compared information on infrastructure and other aspects of economic development in Vietnam with outbreaks of avian influenza. While this research focuses on avian influenza in Vietnam, the study of links between infrastructure characteristics and new and reemerging health risks has broad applicability, especially given the global importance of today’s rapidly expanding urban landscapes.

Abstract:
Highly pathogenic avian influenza (HPAI) is an important public health concern because of its potential to cause widespread morbidity and mortality in humans and poultry and associated devastating economic losses. In this study we examined how perceptions of and response to the risk of HPAI in poultry vary across communes/wards in the north of Vietnam at different levels of urbanization (rural, transitional, urban). We conducted a quantitative household survey with 1073 respondents. Results suggested that the perceived risk of HPAI in poultry was highest in transitional and rural settings. Respondents in these settings were more likely than respondents in urban settings to agree that the process of change (in urbanization, agricultural practices, or natural habitat) increased the likelihood of an outbreak of HPAI in poultry. Compared with others, respondents in transitional areas reported that they do less planning and perceive vaccines to be more effective, while respondents in rural areas reported less perceived ability to separate infected poultry from others. We also found that the inability to respond is not necessarily because of an inability to perceive change but because, rapid and extensive change poses different challenges for poultry management as communes move from rural to transitional to urban settings. Our results suggest that public and animal health campaigns could be tailored in a way that recognizes the needs of poultry raisers in different settings.
