I haven't read most of this thread, but flusurvey has done the first community testing in the UK. They tested ~1000 people and they found ~2% were infected and 20% of them were asymptomatic. This is yet another survey which points to a very low percentage of the population being infected (same in Austria and Iceland).
Almost one thousand participants sent swabs back, and approximately 2% were positive. Among those people who tested positive, 20% did not have any symptoms. Cough and fever were the most commonly reported symptoms among those positive for coronavirus. However the vast majority of people who reported cough, fever and loss of smell tested negative.
