The COVID-19 pandemic drew attention to the critical role of building ventilation as a measure for controlling infection transmission. With the substantial number of COVID-19 outbreaks in care homes worldwide, the effectiveness of ventilation is an important...
This report from Theme 2 researchers on the PROTECT NCS, describes the development and use of a mathematical Computational Fluid Dynamics (CFD) model of respiratory droplet dispersion. The aim of the study was to help provide a better understanding of the physics of...
The aerosol microenvironment is dynamic, exposing pathogens, such as severe acute respiratory syndrome coronavirus 2 virus, when exhaled in respiratory aerosol to extreme conditions of solute concentration, pH, and evaporative cooling. Yet surviving this environment...
Airborne transmission is an infection route for many pathogens such as Tuberculosis (TB), Influenza and more recently SARS-CoV-2 (the virus that causes COVID-19). With respiratory diseases already being a major contributor to pressure on hospital systems such as the...
The National Engineering Policy Centre have produced a new interactive infographic - Ventilation Matters - why clean air is vital to health - exploring why effective ventilation indoors is important for enabling the health and wellbeing of people. Based on the NEPC’s...
This report from theme 2 researchers of the PROTECT NCS, details experimental studies designed to investigate the performance of a new facemask design with impactor plate capabilities for segregating aerosols and droplets by size. This includes collecting and...
This report is an extension of the work of PROTECT Phase 2 and covers the work done under phase 3 of PROTECT, in which researchers from theme 2 of the PROTECT NCS, developed simplified models and introduced two different viral mechanisms anddose-response models. In...
People who test positive for COVID-19 and breathe out virus are more likely to infect their household members than via virus sampled in their nose and throatPeople are most likely to breathe out high amounts of virus early on when they are infectedIf participants were...
As winter continues and energy costs rise, it is tempting to try and keep residents warm and fuel costs down by hunkering down until the weather gets warmer. But keeping all the windows and doors shut may not be the best idea: all homes need ventilation and care homes...
In this blog post, PROTECT NCS researchers Professor Cath Noakes and Alan Beswick discuss how HEPA filter based air cleaners can reduce transmission of respiratory infections. As we enter the coldest months of the year the combination of cooler, damper weather will...
