The outbreak of avian influenza poses a significant threat to global public health and the economy. In recent years, research on its transmission pathways has increasingly highlighted the role of airborne virus carriers. Studies have confirmed that avian influenza can spread through airborne transmission, particularly in environments such as laboratories, live poultry markets, and farms. To effectively control avian influenza, scientists need rapid and accurate methods to monitor the concentration of viruses in the air. Leveraging extensive experience in airborne virus monitoring, Professor Pei-Shih Chen and her research team at Kaohsiung Medical University have developed an innovative technology capable of accurately quantifying the concentration of avian influenza viruses in the atmosphere, enabling early outbreak prediction and prevention.
Advanced Air Sampling and Virus Quantification Technology
Professor Chen's team has successfully developed a groundbreaking technology that combines air sampling and virus quantification, significantly improving traditional virus detection methods. This technique enables the rapid quantification of airborne avian influenza viruses within a short period. The system employs a 37-mm three-layer filter cassette with a silent pump for air sample collection, followed by Real-time qPCR for virus quantification. It overcomes the dilution issues that previously hindered virus extraction processes. Compared to conventional methods, this innovative technology dramatically enhances detection sensitivity, achieving a minimum detection limit of 0.8 copies/m³ and 100% specificity.
The system allows governments and industries to detect the presence of viruses and respond effectively before an outbreak occurs. In addition to monitoring air samples in high-risk areas such as poultry farms and endemic regions, the team discovered a positive correlation between airborne virus concentrations and the presence of specific bird species. For instance, species such as northern pintails and black-faced spoonbills are closely associated with elevated virus levels, providing a scientific basis for early warnings. The application of this technology extends beyond poultry farms to critical areas such as migratory bird habitats, where air monitoring stations can be established in collaboration with local governments and industries to facilitate early warning and control measures.
Pei-Shih Chen: Advancing Epidemic Prevention with Cutting-edge Technology
Professor Chen emphasized that this technological breakthrough represents a significant advancement in monitoring airborne avian influenza viruses. Traditionally, avian influenza prevention measures relied on emergency responses after outbreaks, often leading to mass culling of poultry and causing substantial economic and social impacts. The application of this air monitoring technology enables the early detection of viral traces and the initiation of preventive measures before the virus spreads, significantly mitigating the damage caused by avian influenza.
Professor Chen further noted that the implementation of this technology is not limited to Taiwan but holds potential for global adoption, particularly in high-risk countries. The research team has already established atmospheric monitoring stations in several domestic hotspots and is working closely with government agencies and industry stakeholders on virus surveillance. This technology not only provides rapid analysis of virus concentrations but also delivers actionable prevention recommendations to poultry farmers and government departments, effectively reducing the risk of outbreaks and minimizing their economic and societal impacts.
Looking ahead, Professor Chen underscored that this innovative technology is expected to be adopted worldwide, offering robust support for the global prevention and control of avian influenza.
