Brazil.
Brazil has a number of countries that share borders with it so I've selected the largest of those as a comparison: Argentina, Bolivia, Colombia, Paraguay, Uruguay and Venezuela.
Of those; it has the highest CMR of 6.92% which is still slightly below the global average of 7.05% but well above some of those neighbouring countries and above the 5.07% for the continent.
In terms of cases per 100k of total population (as opposed to the adult population we normally look at), Brazil (49) is well behind Peru which has 143 cases/100k but ahead of all the rest by a significant margin, however, it's not far from the global average which is 43.6 and it's actually below that of the continent which is 52.3.
In terms of deaths per 100k of total population, Brazil (3.4) is second only to Peru which has 4.03 cases/100k but ahead of all the rest by a significant margin as they are all below 1 - the global average is a fraction over 3.0 so there's not a lot of difference.
In fairness, there is a wide spread between the amount of testing being done. Peru has tested 1169/100k people and Venezuela 1698/100k while Brazil has only tested 159/100k.
The daily case trends show Brazil, Colombia and Argentina trending downwards while Peru and Bolivia are trending upward.
