Obviously that does then make it more worrying, because it's much harder to control the spread if most cases are mild and cold-like.
To an extent, I see your point here Mippi (although you are still misrepresenting me). My point is that the symptoms of Covid vary from none at all (& where mass, routine testing occurs eg Irish meat factories, this is the case in nearly 90% of those testing +) to very significant - high temperature, rapid onset & being incredibly ill. And then in between.
What I'm saying is a collection of cold type symptoms, without some defining Covid feature eg a type of cough (& you're wrong on the cough type too, actually) or a significant high temperature is likely though not definitely going to be a cold.
Because not everyone can be tested, you've got to have criteria, and you & many others in the UK are misreading them & having tests unnecessarily & preventing those who need them from accessing them in time.
You ask, reasonably about control: so, wear a mask, properly, really limit your contacts & social interactions, physical distance and practice good hygiene.
These measures are highly successful in limiting the spread & should be much more clearly highlighted in the UK, which they have not been eg the way pubs & restaurants have been operating prior to new measures.
