Started looking this up on Wednesday May 13th, because "7 days
incidence above 500 per million population".
The districts below are manually selected = when you read this, other
districts might have already overtaken them.
BUT: All the included images themselves, however, are regenerated every night = so they are probably up-to-date.
High incidence in the past 7 days (looked up, and ranked
on July 28th
2020 )
at least 200 cases per week per million people:
High 14-days-incidence (if not already mentioned
above):
at least 300 cases per 2-weeks per million people:
Not so much in the past weeks (but had been much
before).
If you want to study past outbreak hotspots,
some of these might be interesting for you to look at, roughly
chronological:
not so many recently, but had many a while ago
Perhaps this page is going to get automated. More ideas:
