> you can't just throw around numbers without explaining exactly what they mean or where they come from.

In the interview, Gieseke says influenza kills 1000 to 2000 people per year in Sweden, it's part of the exchange starting at 24:16. He doesn't explain exactly what those numbers mean or where they come from.

A minute or two later, he guards his 'double' comment by saying it's not going to be 10x.

One interpretation of the exchange is that he's predicting 2000-4000 deaths in Sweden, and definitely not 20000.
