True, but there are loads of similar ‘causes of death’ which are misleading.
My dad had stomach cancer but actually died of a heart attack shortly after being sent home to die. On his death certificate it is down as heart attack. These kind of anomalies make a lot statistics meaningless - even dangerous if certain assumptions are being made falsely.
Which is why so much of the focus has been paid to the number of excessive deaths - the increase in the number of people dying that is normal compared with previous years. And that number is significant. Significant enough to overload the hospitals.
