A lot of the language is "died with Covid-19" not of. It is really difficult to get an accurate figure so they are using all cases where the patient had Covid-19 present. It is always difficult to work out who would have have died with or without Covid-19 present in their body.
Better analysis will come but we are still gathering the data. We are only 6 months in of world wide cases and less than 3 months of UK cases.
The simple things to do is not use YouTube as a source of information unless it is a virologist or immunologist or other related expert and just STAY HOME!
