I have a facebook acquaintance who is a covid denier (and general conspiracy theorist). He has shared a post today which seems to show that there have only been 50 cases of covid 19 reported in the last week using the UK gov notifiable disease report. It seems that covid was added to list of notifiable diseases back in March/April and so should be reported by area each week. Clearly there have been many (many) more cases of covid in the past week than 50, but why are the notifiable disease stats so flawed? I would love to be able to explain this to him.
