Corona virus: traffic lights

The UK is implementing a traffic light system to enable holiday makers to travel to other countries. Red means you can't go, and I believe green and amber mean you can and there is no 14 day quarantine on return. 

I thought I would compare the relative averaged death rates per million between pairs of countries to see if I could make my own list. I decided not to use the current case counts because these numbers are difficult owing to the different numbers of tests being done. The death rate is the least bad number to use.

So for the UK at the moment, the number of deaths per million for the last seven days is 1.64. The death rates for some other countries are shown below.

Brazil - 4.68
USA - 1.88
Sweden - 2.53
Italy - 0.33
France - 0.26
Spain - 0.12

So for travel between the UK and France, the difference is 1.64 - 0.26 = 1.38 which means there is more chance of infection being brought in to France from the UK. If I were the French government, I would set this to red. Travel in the reverse direction would yield -1.38 which means there is much less chance of new infection being brought back into the UK. I would set this to green if I were the UK government. Where the numbers are about the same, I set the colour to Amber. 

Here's the graphic for some interesting countries. 

Read it by choosing a country from the left side and reading along to see whether travel is OK to arrive at another country. It's interesting to see that travel from the UK should really be mostly red. The basic problem is that the UK's death rate is relatively very high compared to other countries.

On the face of it, it seems quite confusing that travel is allowed to other countries from the UK and there is obviously something else driving the decisions.
