MUN scientists testing wild animals to determine spread of avian flu
Scientists at Memorial University in Newfoundland and Labrador are embarking on a study to determine the extent of avian flu spread in the province’s ecosystem by testing wild, fur-bearing animals. This initiative is part of a one-year collaboration between Memorial University, the provincial government, and the Canadian Institutes of Health Research.
Microbiologist Andrew Lang explained that the strain of avian flu currently present is highly adapted and contagious among birds, with the potential to transmit to mammals. The researchers will be analyzing carcasses of various animals such as weasels, lynx, otters, and foxes to assess the prevalence of the virus in these species.
The primary goal of this study is to ascertain the distribution of the virus and evaluate the associated risks for individuals who come into contact with infected animals. While human cases of avian flu in North America have been relatively low, some regions like British Columbia and California have reported severe illness, prompting concerns and emergency declarations.
Although the risk of transmission to humans is considered minimal due to limited interactions with wild animals, trappers are identified as a high-risk group. Lang emphasized the importance of understanding the virus’s potential to adapt and replicate in mammalian hosts, posing a future threat to the broader population.
Trappers have been actively participating in the research by providing animal carcasses for testing at a nominal fee. The response from trappers has been overwhelmingly positive, with over 750 carcasses collected for analysis. This data will be instrumental in developing risk assessments and preventive measures for individuals involved in trapping activities.
The collaborative effort between researchers and trappers underscores the significance of wildlife surveillance in monitoring disease outbreaks and mitigating potential health risks. By studying the spread of avian flu in wild animals, scientists aim to enhance public health preparedness and safeguard vulnerable populations from emerging infectious diseases.
