Just to show how ugly this virus is:
In Germany it started to go downhill when some people in a small area (whole area has 250k people and the main city in it has 40k people) where on a carnival party. Now, some weeks later, we have 589 cases just there even with all the quarantine measurements. Whole of Germany has 4000 confirmed cases right now with ~83m people.
Just imagine what would happen if people could still go to soccer matches, could still go to parties and so on... millions over millions would get infected just in Germany when you see these stats from that small region alone.
