Why isn't the UK testing travellers on arrival?published at 16:25 British Summer Time 28 July 2020
The UK has introduced a 14-day quarantine for travellers arriving from certain countries with higher rates of coronavirus, including Spain, to help stop its spread across borders.
But other countries, such as Iceland, offer travellers the choice of either self-isolating for 14 days or getting tested, if they have stayed in areas with high infection levels.
And Germany is planning compulsory tests at its airports for anyone arriving from a high-risk country.
However, testing is not perfect - and people who have just caught Covid-19 might not yet have sufficient amounts of the virus in their body for the test to detect.
