Health authorities in Thessaloniki announced on Thursday that an 18-year-old man became the fourth person to die of measles in the past year on Tuesday after succumbing to respiratory complications while receiving treatment at the northern port city's Papanikolaou Hospital.

The child, who was not vaccinated against measles and who developed pneumonia, is officially the sixth victim of the infectious disease.
