In Keep Talking Greece there is a daily update on Corona cases. This the latest one
. If you look down the article you will find a map of Greece showing ranges of cases using colour for each Nomos. Currently Chania is in the 0 to 4 range per 100,000 population in a 10 day period. A bit above the map you will find a geographical distribution of new cases recorded that day. If you keep tack of that every day you can do your own calculation.
According to my records there was 1 new case on 17 September, 0 on 18 September and there were 2 new cases on 19 September. There hasn't been any since in the Chania Nomos so that is 2 cases in the last 10 days. The 2011 census for Chania Nomos was 156,585 so I am using a divider of 1.6 which equates to 1.25 cases per 100,000 population in the last 10 days. If there are no new cases here in the next couple of days then that will fall to 0.
I don't think Lasithi have had a case since 11 September so they have been at 0 for some time now.
Either the government is lying to us and there are many more cases or the decision to include Chania in the midnight curfew but not Rethymnon, which is in the 5 to 9 category, is completely crazy.
I doubt if Crete will be taken off any embargo list in the near future because Heraklion is in the 10 to 49 category.
It would be pretty easy to track the daily numbers for each Nomos on Crete and create your own spreadsheet to calculate a whole of Crete figure. Personally I am only interested in what is happening in Chania because that influences my own decisions.
