Passengers on a UK flight to Iceland have been warned they could have been exposed to a measles outbreak on the aircraft.

Icelandair flight F1455 travelled from London Heathrow to Reykjavik on Valentine's Day.

And it's believed a passenger on board may have had the highly contagious virus.

Although measles symptoms may pass within a week, the NHS warns that it can still lead to "serious and potentially life-threatening complications in some people".

Passengers have been urged to contact a doctor straight away if they feel they have the disease - notifying them in advance of a visit so quarantine arrangements can be made.

Iceland's Chief Epidemiologist has warned the crew and passengers that there may have been a measles infection on board the aircraft.

Passengers have been warned of the possible outbreak

Those who have not been vaccinated against measles have especially been encouraged to see a doctor if they have a fever, symptoms of a cold, a rash, or bloodshot eyes.

The announcement from the Icelandic authorities says that those suffering from measles only become contagious once the symptoms begin to show themselves. The disease then remains contagious for between seven and 10 days.
