Infection in the community

We are developing instructional videos to help, for example, teachers and the general public to protect themselves and others around them. This project is being led by Penny Dawson-Malone supported by ANSYS, the Chartered Institute of Environmental Health and Nottingham Film / Media students.

The UK is severely affected by severe restrictions and repeating lockdowns. The economy could potentially ‘re-boot’ if people understood how to wear a mask correctly and understood the science of how this virus spreads.  ENG4 volunteers have seen, first-hand, the intrinsic battle regarding the lack of understanding over mask wearing by the population and how aerosols produced by speaking, coughing, singing or generally ill-fitting masks present a high risk of likely infection to others in their close proximity. Increasing the knowledge of the ‘science of mask wearing’ is likely to increase awareness and improve our behaviour by ‘nudging’ people to behave with consideration and improved understanding.  As such the ‘R’ Value and transmission of viruses should decrease and the risk of infection reduce, leading to a lifting of current lifestyle restrictions.

The animation software and modelling technology held by ‘Ansys’, combined with the knowledge of a Public Health professional  enables us, for example, to produce a Public Health film based in a supermarket setting with  digital ‘overlays’ of how COVID-19 aerosol transmission occurs in animation format caused by inappropriate mask wearing.

Examples of poorly worn face masks

Penny Dawson Malone Chartered EHP said, ‘If people could see the aerosols produced by speaking, coughing, singing or by using a generally ill-fitting mask, then they would understand how a mask can protect others as well as themselves. It has been a fascinating opportunity to work with ‘Ansys’ Application Engineers and develop a film with scientific modelling which is based on peer reviewed journals in engineering and medicine‘.
