1/ UPDATES TO COVID-19 AEROSOL TRANSMISSION ESTIMATOR

We have just implemented several updates:
- added increased risk of variants
- made clearer how to enter vaccinated people
- added calculation of infection risk parameters

2/ The risk parameters allow quantitative decisions on which mitigations are needed to avoid outbreaks. See the thread from yesterday on that topic and paper:

3/ We also added a sheet with a quantitative version of the BMJ table (bmj.com/content/370/bm…). See sheet "Risk Table", where you can modify it for your conditions.

4/ Based on feedback @ZheP_AtmChem is about to add 2 new versions of the Table, to see which one people find more useful.

5/ We are going to make some additional updates. If you have suggestions, please enter them in this form:

6/ Note that the estimator has a goal of making the calculations explicit ("open source") and to be easy to modify and adapt for people familiar with spreadsheets.

There are other estimators that do the same calculations but may be easier to use. E.g. …re-modeler-data-devils.cloud.duke.edu

7/ As part of the update I also wanted to link to all the other airborne transmission estimators out there. To my knowledge they all do the same thing, but vary on the details.

If you know of one that we are not linking to, please enter it at forms.gle/DcYETdg1dFaV2V…

8/ We've added two new versions of the Table today, discussed here. Poll asking for feedback on that thread.
