- Quick Guide:
- This tool simulates the long range airborne spread SARS-CoV-2 virus in a finite volume and estimates the risk of COVID-19 infection. It is based on current scientific data and can be used to compare the effectiveness of different mitigation measures.
- Virus data:
- SARS-CoV-2 covers the original "wild type" strain of the virus and three variants of concern (VOC):
- - Modify the default as necessary, according to local area prevalence e.g. for Geneva - or Ain (France).
- Ventilation data:
- - Activity types:
- The type of activity applies to both the infected and exposed persons: - - Activity breaks:
- - Refer to COVID Calculator App user guide - for more detailed explanations on how to use this tool.

- CARA is a risk assessment tool developed to model the concentration of viruses in enclosed spaces, in order to inform space-management decisions. -

-

- CARA models the concentration profile of virions in enclosed spaces with clear and intuitive graphs. - The user can set a number of parameters, including room volume, exposure time, activity type, mask-wearing and ventilation. - The report generated indicates how to avoid exceeding critical concentrations and chains of airborne transmission in spaces such as individual offices, meeting rooms and labs. -

-

- The risk assessment tool simulates the long-range airborne spread SARS-CoV-2 virus in a finite volume, assuming a homogenous mixture, and estimates the risk of COVID-19 airborne transmission therein. - The results DO NOT include short-range airborne exposure (where the physical distance is a significant factor) nor the other known modes of SARS-CoV-2 transmission. - Hence, the output from this model is only valid when the other recommended public health & safety instructions are observed, such as adequate physical distancing, good hand hygiene and other barrier measures. -

-

- The model used is based on scientific publications relating to airborne transmission of infectious diseases, dose-response exposures and aerosol science, as of February 2021. - It can be used to compare the effectiveness of different airborne-related risk mitigation measures. -

-

- Note that this model applies a deterministic approach, i.e., it is assumed at least one person is infected and shedding viruses into the simulated volume. - Nonetheless, it is also important to understand that the absolute risk of infection is uncertain, as it will depend on the probability that someone infected attends the event. - The model is most useful for comparing the impact and effectiveness of different mitigation measures such as ventilation, filtration, exposure time, physical activity and - the size of the room, only considering long-range airborne transmission of COVID-19 in indoor settings. -

-

- This tool is designed to be informative, allowing the user to adapt different settings and model the relative impact on the estimated infection probabilities. - The objective is to facilitate targeted decision-making and investment through comparisons, rather than a singular determination of absolute risk. - While the SARS-CoV-2 virus is in circulation among the population, the notion of 'zero risk' or 'completely safe scenario' does not exist. - Each event modelled is unique, and the results generated therein are only as accurate as the inputs and assumptions. -

-

- CARA has not undergone review, approval or certification by competent authorities, and as a result, it cannot be considered - as a fully endorsed and reliable tool, namely in the assessment of potential viral emissions from infected hosts to be modelled. -
