Public Health Wales say they are aware of a "possible death from measles."
In a statement they said that the death of a 25 year old in Swansea is being investigated by the Swansea Coroner and that the "diagnosis of measles has not yet been confirmed."
My sympathies are with the family at such a tragic time.
Whatever the cause of death in this case, we should not be surprised if, as the outbreak grows, we start to see deaths in Wales.
Measles is a potentially fatal disease and around one in every 1,000 people who contracts measles in developed countries will die.
