In IOM-Research/CEMRA: COVID Exposure Model and Risk Application

IOM developed a quantitative microbial risk assessment (QMRA)-based app during the PROTECT project
A QMRA is a model that takes the best estimates of characteristics of a working location and the behaviour of the people in it to understand how viruses 'move' within a room.
We are interested in how much of the virus ends up in peoples lungs and how much of it contacts their mouth and eyes
We can then simulate what would happen if we make a change to the room or the behaviour of people. For example we might ask what happens when we open a window and allow fresh air to enter the room.
The app allows the user to understand the impact of a combination of control measures (i.e. PPE AND hand/surface cleaning AND a UV air cleaner) and how they can affect routes of transmission (i.e. through air, surfaces and close contact) differently - this is more reflective of the real world experience.
We've made this app with pre-loaded scenarios so that members of the infection control or occupational health workforce can get a sense of how changing work protocols could lower the risk of transmission.
More workplace-specific scenarios can be developed in collaboration with the IOM
The underlying model and app is open to development for scientists and developers and can be found on the IOM github page
