Human and animal exposure to the SARS-Cov-2 virus via inhaled air

Quantitative evaluation of human and animal exposure via inhaled air within the context of the COVID-19 pandemic and evaluation of risk reduction measures

There are many questions surrounding transmission of the virus in the air responsible for Covid-19. The objective of the University of Liège is to study this transmission via inhaled air both in humans and in pets, and to have a better understanding to prevent and protect human and animal health.

Air transmission and prevention

The current consensus is that the SARS-CoV-2 virus can be transmitted by air. Furthermore, cases of transmission to domestic animals have been reported. Getting a better understanding of the transmission mechanisms is a public health priority. The University of Liège is developing a double quantitative evaluation model for human exposure and animal exposure to the SARS-Cov-2 virus via inhaled air. Its objective is to evaluate risk reduction measures and advise politicians and healthcare professionals about the risks and the means of prevention.

The project is divided into 3 phases:

  • Development of a quantitative model of human and animal exposure via inhaled air: transmission diagram, mathematic transmission model for quantifying human and animal exposure according to various variables, analysis of sensitivity and exposure scenarios
  • Evaluation of exposure risk reduction measures (between humans, between humans and pets)
  • Recommendations for reducing air exposure to SARS-Cov-2 of exposed individuals (healthcare professionals, the general public, pet owners)

How the Air Liquide Foundation is participating

The financial support from the Air Liquide Foundation is dedicated to paying the salaries of specialist personnel and to the operational costs of the project.
