LONDON (Reuters) - Passengers who were on a flight from Zante on the Greek island of Zakynthos to Cardiff in Wales last week have been told to isolate after it was identified as the source of at least seven confirmed coronavirus cases, Public Health Wales said on Sunday.
Greece, which is not on the list of countries under British quarantine rules, is a popular holiday destination and more tourists are expected to have visited this year after several other favourites, such as Spain, were put under restrictions.
"Cardiff and Vale Test Trace Protect and Public Health Wales have identified at least seven confirmed cases of COVID-19 from three different parties who were infectious on TUI (LON:TUIT) Flight 6215 from Zante to Cardiff on 25 August," said Giri Shankar, incident director for the novel coronavirus (COVID-19) outbreak response at Public Health Wales.
"As a result, we are advising that all passengers on this flight are considered close contacts and must self-isolate," he said in a statement.
Shankar added that investigations had found that the virus had spread to other groups of people because of "a lack of social distancing, in particular by a minority of the 20-30 year age group".
After a stringent lockdown to combat the coronavirus pandemic, Britain is easing restrictions to try to boost the economy, but its four nations - England, Wales, Scotland and Northern Ireland - have made changes at different speeds.
