Three more cases of Legionnaires’ disease have been confirmed in UK residents who have visited Corfu, bringing the total number of cases to 12, the Health Protection Agency (HPA) said.
The HPA said three other possible cases in people who travelled to the Greek island in the past three months are still under investigation.
As a precautionary measure, the HPA was looking into the possibility of a UK source but a spokeswoman said preliminary investigations have so far not found a common link between the patients – whose ages range from 39 to 79 – other than they all visited Corfu, albeit different parts of the island.
Greek health authorities have sent two teams to Corfu and over the past week water samples have been taken from hotels and other venues.
Professor Nick Phin, head of the HPA’s Legionnaires’ department, said Legionnaires was uncommon and cannot be spread from person to person but warned people to be aware of the risks.
