In terms of recovery rates (well more accurately, active case rates), a handful of countries have no currently active cases despite having had some: Anguila, Greenland, St Barth and Yemen of which only the latter shares a land border with anyone effectively.
China (if we believe the numbers) is under 1% active cases while French Polynesia, Cambodia and the Faeroe Islands all have single digit active cases and percentages below 5%.
Australia (14.68%) and New Zealand (15.33%) are well below the global average of 63.4% while some countries have a long way to go with percentages over 90% and even the UK is still at 84% and the USA at 80.52%.
