Our CDT response to the

coronavirus pandemic

Covid-19 and related inhalational infections - Focus Meeting 16

The Aerosol Society presents ‘Covid-19 and related inhalational infections: Current trends, future challenges and opportunities in aerosol science’. A four-part series on aerosol transmission of COVID19 and other infectious aerosols covering key aspects: sources, aerosol generation, transmission, sampling, diseases, control measures and mitigations.

Understanding the factors that govern the transport of viruses by aerosols and droplets is critical to identifying the dominant mode of transmission and the relative risks of the contact and airborne routes, the appropriate use of personal protective equipment, and the use of mitigation strategies. Although our understanding of the transmission of SARS-CoV-2 is developing rapidly, much remains that we just do not know.
Researchers from the EPSRC Aerosol Science CDT have risen to the urgency of the challenges in tackling the COVID-19 pandemic. Here, we review what is known about the transmission of the virus and what remains uncertain. We also highlight the contributions made by CDT academics to address the transmission of SARS-CoV-2.

SARS-CoV-2 Aerosol Mechanisms

You can now view an updated version of SARS-CoV-2 Aerosol Mechanisms on The UK Aerosol Society website where data for these mechanisms has been transitioned. 

Aerosol/ Droplet Expiration

Concentration, Size and Viral Load

Aerosol Generating Procedures

Aerosol/Droplet Transformation

Evaporation and hygroscopic growth

Aerosol/Droplet Transport

Advection, turbulent mixing and diffusion

Aerosol Exposure

Physical transport (droplets) and aerosol inhalation

Publication Database

Our initiative aims to review literature relevant to SARS-CoV-2 and aerosol/droplet spread by the mechanisms highlighted above. Our SARS-CoV-2 publication database includes summaries of each article highlighting relevant findings on mechanisms.

Articles within the database may be exported or viewed directly from the publication website. Each article contains, within the abstract field, our summary of the article relating to aerosol mechanisms relevant to SARS-CoV-2. The original author abstracts can be found by going to the article’s hosting journal, which will include full details of the article and supporting information.

Contributors Resources

We monitor publications relevant to the spread of SARS-CoV-2 virus via aerosols and droplets and our team of editors and reviewers select articles to summarise, drawing conclusions that fall within the defined mechanisms. By doing this, we hope to raise awareness and expand our collaboration with academics from all over the world who can contribute in extracting new findings to the spread of SARS-CoV-2 virus and build a database of resources unique to the aerosols and droplets research.

Anyone wishing to be involved and be part of our team of editors and reviewers are welcome to contact Dr Adam Boies for further information.

News

Our academics regularly make the headlines. From life-changing research to enterprising partnerships, major awards to charitable endeavours, the Aerosol Science CDT in Bristol is bursting with inspiration. 

Read some of our headlines here: 

“The research project, known as PERFORM (ParticulatE Respiratory Matter to InForm Guidance for the Safe Distancing of PerfOrmeRs in a COVID-19 PandeMic), partly led by Prof Jonathan Reid, corresponding author on the paper, has had a global media coverage of over 300 articles, reaching an audience figure of 4.8 billion for each media outlet that covered the story, which is an unprecedented figure.”

Aerosols and the Coronavirus

This BBC report relates to our work examining the survival of the virus while suspended in aerosol droplets involving Allen, Henry and Mara with collaborators in CMM (Adam Finn, Andrew Davidson, Darryl Hill) and the Vet School (Tristan Cogan and Jamie Mann).

Virtual Seminar Series

Our academics are greatly involved in scientific talks related to the spread of the virus. Take your time to watch the videos here below. 

Aerosols and the Coronavirus

Aerosols and droplets play a critical role in the spread of COVID-19. Questions remain about the possible airborne spread of the virus, SARS-CoV-2, in small respirable size particles which people emit when they speak, cough and sneeze. The competition between sedimentation, evaporation and forward momentum in the exhaled jet from sneezes and coughs governs the transmission of the virus over shorter distances in larger droplets, contaminating surfaces.

In this short video interview with the University of Bristol, Pro Vice-Chancellor, John Iredale, CDT Director Jonathan Reid talks about some of the research underway to understand the airborne transmission of the virus.

Scientific Understanding and Modelling of the Decontamination of COVID 19 Infected Spaces and Surfaces

1st May 2020

Listen to Prof. Jonathan Reid give a talk to the UK fluids network on the underlying science spanning from the jet dynamics, evaporation, and through to viability/infectivity, including a survey of the most important work.
