Measles cases confirmed on Isle of Man
Health officials on the Isle of Man are urging parents to get their children vaccinated against measles after a "small number" of confirmed cases.
Everyone under the age of 40 has also been advised to check their immunisation history.
All of the cases in the Isle of Man have been in adults aged over 20.
The department of health said investigations suggested those affected caught the illness on the island but the initial source was still unknown.
A spokesman said two of the patients had complications and one developed pneumonia and required treatment in intensive care.
He added: "There have been major outbreaks of measles in many European countries.
"Recent arrivals from European countries to the Isle of Man need to ensure that they are registered with a local GP to obtain health care and ensure that all members of their family are fully immunised."
The department warned that measles in adults could cause serious complications such as pneumonia, encephalitis and middle ear infection.
