All passengers who took a flight from Zante to Cardiff have been ordered to self-isolate after seven cases of coronavirus were confirmed.
Passengers who were on TUI flight 6215 on Tuesday are now being considered as “close contacts” of those who tested positive for COVID-19.
The seven cases were from three different parties on board the flight from the Greek party island, which is also called Zakynthos.
Dr Giri Shankar, Public Health Wales director, said: “These passengers will be contacted shortly, but meanwhile, they must self-isolate at home as they may become infectious, even without developing symptoms. Anyone with symptoms should book a test without delay.
“Our investigations into a number of cases of coronavirus have indicated that a lack of social distancing, in particular by a minority of the 20-30 year age group, has resulted in the spread of the virus to other groups of people.”
