In my town, in one care home, 22 residents, 10 have just passed.

@HannahSkyPeople in care homes are most likely to be at the upper quartile of life. People in the upper quartile of life are more likely to pass, statistically. How do we get to 'the truth'.

@Valentine If you're in a nursing home, it's likely you have multiple health issues which overall will weaken your immune system, ability to fight disease. Having multiple chronic diseases and frailty is in some ways as or more important than chronological age. An 80-year-old who is otherwise healthy and might be more resilient in fighting off infection than a 60-year-old with many chronic conditions. Living in a nursing home whether for the rest of your life or temp skilled nursing for post surgery or illness it's highly likely they will be at higher risk for fighting the virus.

@Valentine It's not that so much as the fact that as you age your breathing capacity is likely to be hindered by things [b]known[/b] like Emphysema; pulmonary problems; Asthma; pleural effusion (water around the lungs) and they can be life-threatening in themselves.
But if the person was considered reasonably 'well' prior to 'lockdown' even WITH these problems, and there are known cases of covid-19 in their living space, it's quite likely that will be THE factor that causes their end of life.
