Despite having the highest death toll so far, Italy's coronavirus deaths are far higher than reported, with thousands dying but never being tested

I don't think the general premise of this article will be surprising to anyone, but it has a lot of interesting (and sad) details and stories included. There are also some specific numbers that can hint at how far off the official counts could be, for example:

In the wider Bergamo province, which comprises the city and more than 240 small towns and has a total population of 1.1 million, 2,060 people died in March from the virus, according to the official count. But some 4,500 more people died in the province in March than a year earlier, according to a new joint study by the local Eco di Bergamo newspaper and research firm InTwig that took data from 91 towns in the province.
