Jim,
I've been trying to get as close to the source as possible when posting COVID information, and the best source that I know of for St Barth numbers is ARS Guadeloupe, the Regional Health Agency which covers Guadeloupe and "the Northern Islands", St Martin and St Barthélemy. I wouldn't mind a touch more consistency in the timing and the periods covered in the ARS reports, but I post what I find. Here's a summary of what I've found over the last few months:
July 18 – July 24 – 7 cumulative cases, +0 from the previous report
July 25 – July 31 – 9 cumulative cases, +2 from the previous report
July 31 – August 5 – 10 cumulative cases, +1 from the previous report
August 5 – August 8 – 13 cumulative cases, +3 from the last report
August 8 – August 11 – No change from the previous report
August 12 – No change from the previous report
August 8 – August 14 – No change from the previous report
August 14 -August 17 – 16 cumulative cases, +3 from the previous report
August 15 – August 21 – No change from the previous report
August 22? - August 25 – 17 cumulative cases, +1 from the previous report
August 22 -August 28 – 18 cumulative cases, +1 from the previous report
August 28 – September 2 – No change
August 29 – September 4 – 21 cumulative cases, +3 from the previous report
September 5 – September 13 - Gap, no report
September 14 – September (no range given) 23 cumulative cases, +2 from the previous report
September 14 – September 20 – 45 cumulative cases, +22 from the previous report
September 21 – September 27 – 54 cumulative cases, +9 from the previous report
September 28 - October 4 - Gap, no report
October 5 – October 11 – 67 cumulative cases, +13 from the previous report
The numbers for the month of September and the first half of October may be the source of the CDC's change in status.
