Professor Philip Nolan:

Testing alone will not provide significant protection, largely because of the number of cases that the testing will miss. On the other hand, as the Minister stated, testing as part of an EU-wide regime of prior risk assessment and perhaps some level of isolation on travelling from high-risk countries would be effective. There is no point in introducing point-in-time testing as a way of screening incoming passengers. It will miss too many cases and create too many false positives. A well-worked-through international regime for safe travel is a plausible way forward.
