which seems fair enough - but I cannot see if one can select a Covid-19 "Cause".
Will a new "Cause" be downloaded into this drop-down field to allow crunching any Covid-19 specific tasks?

UPDATE: OK, I found a useful resource here and it shows which project you might be crunching for:
I think this is shown in the "PRCG" section of the "Work Queue".How do I know that I'm working on COVID-19 related projects ?
If you're running a project that's listed here, you're fighting COVID-19 :
