Of the 124 cases, 10 were hospitalised.
The vast majority had not been immunised against measles, Dr Bell said, and only five were fully immunised with two doses of the MMR vaccine.
"I would like to take the opportunity to say a big thank you to all those who helped or were involved with the outbreak, this includes parents, students, schools and general practices," she said.
"We would like to take the opportunity to continue to encourage all to check their vaccination status and, if you have not had two MMR vaccines, to please get immunised."
A further 110 people who had symptoms and a rash similar to measles were found not to have the disease.
