I would have thought that every country did if you are tested positive and you die.
Certainly in Australia almost all of our recent cases have been in nursing homes. One home had 19 deaths.
In total though we have only had 10 deaths in the entire continent in the month of May.
Most states still have border closures, but in New South Wales (most populated state of about 8M) you can travel the state now and almost everything is open from Jun1.
Major sport is back without spectators. 6 million have downloaded the app.
Anyone arriving from overseas or into a closed state get 14 days mandatory isolation.
So all looking pretty good at the moment.
I think the problem has been due to a shortage of testing equipment, which makes it an issue of priorities. People in nursing homes tend to die at a far greater rate than people in the general population, with or without the presence of the Covid virus.
However, when comparing the death rates from Covid-19 in different countries, in order to assess the effectiveness of the varying degrees of lock-down, the inclusion or exclusion of Covid related deaths in nursing homes and aged care homes, can skew the comparison.
For example, Sweden has come under a lot of criticism for refusing to implement a government controlled lock-down, and their relatively high death rate per capita suggests they might have done better if they had enforced a lock-down.
However, if Sweden has always included Covid-19 related deaths in nursing homes, whereas many other countries have only recently started to include Covid related deaths in nursing homes, then the reported death tolls from Covid-19, in various countries, are unreliable for the purpose of lock-down comparisons.
Here are a few articles which address the problem.
"Many countries in Europe have essentially ignored coronavirus testing in nursing homes to focus their testing capacity on hospital patients and hospital staffers. In Italy, for instance, a recent national health service report indicated that people dying in nursing homes were overwhelmingly unlikely to have been tested for the virus.
Many countries have not been carefully tracking deaths outside of hospitals, either.
“The challenge is we don’t have very good information for people in care homes,” said Adelina Comas-Herrera, a researcher at the London School of Economics."https://www.washingtonpost.com/world/europe/nursing-homes-coronavirus-deaths-europe/2020/04/23/d635619c-8561-11ea-81a3-9690c9881111_story.html"The United States does not know how many people are dying from COVID-19 in part because the government is only just now requiring nursing homes to start reporting numbers of presumed and confirmed cases and deaths to the federal Centers for Disease Control and Prevention.
The missing cases could dramatically skew the national death count. When France started reporting death data from some of its nursing homes, the daily COVID-19 fatality numbers almost doubled."https://theconversation.com/failure-to-count-covid-19-nursing-home-deaths-could-dramatically-skew-us-numbers-137212"Residents of nursing homes have accounted for a staggering proportion of Covid-19 deaths in the US, where more than 85,000 people have died. Privately compiled data shows that such deaths now account for more than half of all fatalities in 14 states, according to the Kaiser Family Foundation. But only 33 states report nursing home-related deaths, so the true extent of the problem across the state remains unknown."https://www.theguardian.com/world/2020/may/16/across-the-world-figures-reveal-horrific-covid-19-toll-of-care-home-deaths
