Actually, St Barts isn’t doing as well as you think. Last Wednesday they reported 27 new cases for the previous week, and they already had 11 new cases for last week. St Martin (French side) had 9 new cases the previous week, and 2 new cases as of last Wednesday. The population of St Martin is about 36,000, and St Barts is just under 10,000. St Martin and St Maarten are both doing better than St Barts.
