Edenvale ward councillor Heather Hart advised measles is spreading.

Measles, also known as rubeola, is a viral infection of the respiratory system.
Measles is a very contagious disease that can spread through contact with infected mucus and saliva. The coughing or sneezing of an infected person can release the virus into the air.
Your doctor can confirm measles by examining a skin rash and checking for symptoms that are characteristic of the disease such as white spots in the mouth, a fever, coughing and a sore throat.
