Appearing on BBC Radio 4’s Today programme, Prof Heymann, of the London School of Hygiene & Tropical Medicine, was asked if restrictions such as testing for people arriving into the UK were useful.
He said: “Testing strategies are useful in identifying people who are infected, and those people can then isolate themselves or seek treatment, and it stops transmission. So they are effective. But they must be used in a testing strategy that’s also well thought out and can actually identify people infected, and then follow up to be sure that they are isolating, either self-isolating or being managed in a health facility.”
Asked if “we have that at the moment”, Prof Heymann replied: “We have those tests, yes. We have many different tests, we have many tests, we have therapeutic agents, we have vaccines, but many times those tests have not been used in the most appropriate manner.
“But gradually, as people are understanding the value and the capacity of these tests, they are being used in travel and in many other instances as well.”
