I can't filter who might have disappeared from the forum because of the virus but you can get some hints by just check regularly Top 1000 merit receivers who were not active the past 30 days. Then you know who is "gone" for a while.
Then I should start updating this list more often.
We have a really bad flu here in Norway (not the corona one) and many people die from this one too, you can't focus only on covid-19, accidents happen every day.
Stay safe people
