Of course it is a concern - but even though you test on arrival you go to your hotel, so still nobody is going to take our daughter in the airport.
We know the risk, but the way it’s looking now, quarantine (and hopefully testing on arrival) will be gone by July.
Still we can’t predict this virus, a new variant my emerge and cause another havoc, then we have a new situation and will have to assess our travel plans.
During the pandemic we’ve been traveling to UAE, Portugal, Iceland and Maldives without any problems.
I know: it only takes 1 positive, but in Denmark at one point I got tested (PCR) once a week (it’s free to get a test in Denmark, and encouraged at that point to test weekly)- working in a school, no masks allowed - so many, many tests (and even more quick tests) all but 1 negative (and got very sick))
