There hasn't been much flu around this winter, so if a frail old man in a care home with a covid outbreak, goes downhill and dies, it's more likely to have been covid than a random case of flu. The article doesn't say what type of test the care home mentioned, was using. If it's lateral flow, they're less sensitive so more likely to be false negative. We just don't know.
If our elderly loved one contracted Covid during a hospital stay, appeared to rally & went home but never quite recovered, died 3 weeks later and their death certificate didn't mention Covid, wouldn't we think there was a 'cover up' going on?
There's no doubt that real, tested Covid was making people ill, with a recognisable pattern of illness, and filling up our hospitals just a few short weeks ago. A few of the death counts might be flawed around the edges, but it's better than no count at all.
