The Times today. 7 day tests to replace isolation19 Jun 2021 20:12
The Times also has this story. They say 62000 people were pinged last week for self isolation. They will be able to have tests for 7 days instead if the pilot recommendations are accepted. 62 000 x 7 x 52 weeks is:
22,568,000. Now, imagine all the people who haven't downloaded the app because they don't want to isolate? Actually the majority of us. But we may want to travel in the near future. So what if another 7 million of us downloaded the app. Or even 50% of the population downloaded the app. You can very quickly see how low level prevalence can reach 50, 60, 70 million tests a year. Add in a test for every child going on holiday with their parents before departure and two more on arrival.
I'll do the maths for normal Heathrow travel tomoz. Or you can?
