Project Details


The COVID-19 pandemic is a respiratory infectious disease and it has caused global health concern. WHO has identified airborne transmission as a principal route for SARS-CoV-2, especially in crowded and poorly ventilated indoor environments. The current prevention measures recommended by the authorities are primarily applied to control contact and droplet transmissions, but their protective effects regarding airborne transmission are still unclear. The REACT project aims to provide a further understanding of the mechanism of airborne transmission and evaluate the performance of prevention measures in reducing the airborne infection risk under critical
scenarios. In the project researchers from Aalborg University will develop a ‘realistic’ respiration manikin to simulate human breathing, coughing, and singing events, and further use it to quantitively evaluate the protective effects of prevention measures practically applied during COVID-19 and potential ventilation solutions.
The project is funded by Independent Research Fund Denmark (DFF).
