There are so many unknowns from this report that it is hard to make much from it. Some of the major questions.

1. How many people in this town ended up in hospital? How many are still in the ICU and likely to die?

2. Is the population sero tested representative of the town population? Was this population sampled biased by those who had obvious symptoms being more likely to participate?

3. Are the 15% positive representative of the German population or is it skewed to the young?

4. How was the accuracy of the serology test determined? >99% is impressively accurate if true.
