During the four-week period, participants’ geography, age, sex, ethnicity, key worker status and symptoms were noted.
The data revealed there were, on average, 13 positive cases for every 100,000 people. This amounted to a reproduction rate of 0.57.
Moreover, the report showed anybody who had come in contact with a known COVID-19 case was 24 times more likely to test positive for the virus themselves.
The study has been extended for the month of June, which has been upscaled and is due a peer review before publication.
