Well we are closing down schools and universities here, atleast till the big elections/referendum day (22nd of April).
Roskomnadzor reported yesterday that a total of ~110k tests were made by that point.

So far atleast in my local area there were no runs on the supermarkets (but then I am in a fairly low density area in terms of actual residents).
