Cold or Flu?

Here's a note from a friend in Montreal:
A leading German research hospital (Charité) has developed an excellent online self-evaluation tool, for anyone wondering if they just have a cold, or should seek testing. It's more thorough than anything I've seen in Canada, so far.
You can do it in English or German, and it's free.
I hope this is helpful in calming fears.
Courage!
