San Marino has a COVID-19 death rate of 943 per million population (third column from left):
— Coronavirus Update (Live): 1,256,358 Cases and 68,229 Deaths from COVID-19 Virus Outbreak - Worldometer (April 5)
This is more than 100 times the reported 8.8 global average.
It actually exceeds the rates of the next 4 highest countries combined.
Is this extreme difference merely a statistical anomaly due to the country's relatively small population, or is there something fundamentally different happening there?
