> But such comparisons can be misleading. Unlike the UK, Italy or Spain, Belgium counts all coronavirus deaths outside hospitals in its daily statistics: deaths in care homes account for 53% of the total. Belgium’s official toll also includes people suspected of having died of coronavirus, without a confirmed diagnosis. Nearly all deaths in care homes (94%) are suspected Covid-19 cases, rather than confirmed – an approach that has led some to complain Belgium is overestimating the number of fatalities.
(They probably aren't over counting. Covid-19 is devastating for nursing homes and care homes).
