How airborne diseases spread and how we can stop them
About
Airborne respiratory diseases such as tuberculosis, Covid and flu are all transmitted the same way: the disease is carried in tiny particles called aerosols, which we breathe out constantly – especially when speaking loudly or singing. The particles are small enough to float in the air like smoke, and if someone has the disease, their exhaled aerosols contain the pathogen, and can infect someone who breathes them in. We stop the disease spreading by stopping people inhaling infected aerosols.In this talk, we will discuss how aerosols behave, how we can reduce the spread of diseases indoors, and how ventilation, filtration, distancing, masking and other technologies can play a role.
Adam Squires is an aerosol scientist in the Department of Chemistry at the University of Bath. He has published articles on Covid and aerosol science in the British Medical Journal and the Independent
The Minerva Series is a public lecture series run by the University of Bath.
