Using the terminal post code you need to focus on the airport where the case rate is 124.7 per 100,000 compared with the U.K. average of 23.4

This is one of the highest rates in the UK and 5 times the UK average despite the area being relatively well off. I wonder how many cases are being transmitted at the airport where many people in Wigmore walk to work? I also wonder how many cases are being brought into the UK each day via Luton Airport through foreign travel despite the testing as the council is still blaming this as one of the main reasons. The worst might be over but I expect a surge in the coming months as most of the retail outlets are still closed so despite the low passenger numbers people are still crowded together and that is with an average of only 100,000 passengers a month as the flights are bunched.
