In the last year I know four people who have died. Two died from heart attacks. Straightforward, no complications, no mention of Covid. But...the other two both had Covid on their death certificates. Neither had been tested; both died in places where there was no known outbreak (one in hospital, one in a care home). One had no symptoms of Covid whatsoever (she was 95 and could have died of anything at any time and nobody would have been surprised). The other had suffered serious lung disease for five or more years and was given less than six months to live some eight months earlier. Again, nobody was surprised that she died. She obviously had severe breathing difficulties but otherwise she displayed no symptoms of Covid.
I know that since they had not been tested they would not appear on the figures that are published each day. But they would have been included in the higher figure where Covid is mentioned on the death certificate. I don't know why and neither does anybody else.
