Andrea and the kids went back to Germany (on an "evacuation flight") in June. I went to visit them last week. Leaving Kenya, you don't need to get tested, but the arriving country, in this case Germany, does require it, with a negative test taken in the 48 hours before landing to avoid quarantine or instead taking a test on landing and then once the results are out, being able to leave quarantine.
I tried the test here, but the results didn't take the 2 days they were supposed to take. Instead they took 4 days and I'd already landed in Germany and got a negative result from a test there, in Frankfurt airport (within 4 hours of doing the test).
I had taken the dog with me, which was an extra level of complexity, though ultimately fairly smooth. There was a long queue outside the airport for the first security check (the trolleys were good at keeping social distance) and the temperature check, though inside less spacing whilst checking-in. Everyone wore masks of course. The lounges were closed, and there was no fingerprinting at the immigration desk. Every other chair was blocked off, but otherwise most things were fairly normal. On the plane, apart from wearing masks, the food and entertainment was all normal. On arrival in Frankfurt and then taking the train it was the same really. In fact as the train got further out of the big cities fewer people bothered with masks. I don't think anyone bothered with the hand sanitizing in the airport.
Germany has a stellar reputation for managing COVID-19, with an efficient, quick lockdown accompanying a strong healthcare system and strong, locally managed, contact tracing systems. With very few cases for weeks, especially in the rural areas where we were, life was basically as normal... in theory people were supposed to wear masks in indoor places, but in many cafes and restaurants people were not (and it is not required outdoors).
So it felt thoroughly strange after 4+ months in Kenya of wearing masks outdoors and indoors, and even whilst running. It also felt strange actually doing fun things - from theme parks to river rides, visiting tourist attractions like castles etc (although nowadays these things are open in Kenya too, but with masks). We even went to a pub (closed in Kenya) and various ice cream or food restaurants where there was no social distancing (unlike Kenya).
Returning to Kenya (having taken another COVID test in Frankfurt airport a few hours before boarding) we had to show the negative test result at immigration as well as fill in our contact details (and I was getting an SMS message every morning after arriving reminding me to update my health status in the app the government asked us to download and use).
Now it is back inside with a computer screen and phone most of the day, with daily runs, and rare physical social interactions with other people. Just lots of online video calls and phone calls, including with my family!
