Researchers from the Universitat Rovira i Virgili have discovered that temperature differences significantly affect how aerosol clouds from coughs and sneezes disperse in indoor environments. The study demonstrates that temperature gaps cause these respiratory droplet clouds to remain denser and travel farther than previously understood. This adds to the known factors affecting aerosol dispersion, which already include exhalation force, respiratory system morphology, and spatial characteristics.
Why it matters
This finding has important implications for designing ventilation systems and implementing infection control measures in indoor spaces such as hospitals, schools, and offices. Understanding how temperature affects pathogen-carrying aerosol transmission could help reduce the spread of respiratory diseases including influenza, COVID-19, and tuberculosis.
When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these aerosols disperse in the air is crucial for minimizing the transmission of pathogens in indoor spaces, but their dynamics are complex and depend on many factors: the force of the exhalation, the morphology of the respiratory system, the characteristics of the space, etc. Now, a new study led by researchers from the Universitat Rovira i Virgili has shown that temperature also plays an important role.
