Sydney Residents Advised to Check Measles Immunisation
16 Mar 2026
Some of the cases were reported in South Western Sydney, raising concerns the virus may be spreading locally.
According to NSW Health, exposure sites linked to the cases have been identified and published online so the public can stay informed.
How measles spreads
Measles is one of the most contagious diseases. It spreads through the air when an infected person coughs or sneezes.
Even being in the same room as someone with measles can lead to infection if you are not protected.
Common symptoms include:
-
fever
-
red or sore eyes
-
runny nose
-
cough
A red rash usually develops a few days later. In serious cases, measles can cause pneumonia or swelling of the brain.
Protection through vaccination
The measles vaccine is very effective. Two doses provide about 99% protection.
High vaccination rates also help protect vulnerable people such as babies, pregnant women and those with weakened immune systems.
Why outbreaks still happen
Although Australia eliminated continuous measles spread in 2014, the virus is still common in some countries. Many infections start when someone catches measles overseas and returns to Australia while contagious.
Lower vaccination coverage can allow outbreaks to occur.
If you are unsure about your vaccination
People born after 1965 who are not sure if they have received two doses can get a free catch-up vaccination through the National Immunisation Program.
Your GP or practice nurse can check your records and arrange vaccination if needed.
Where to get vaccinated
Vaccines are available from:
-
GP clinics
-
some pharmacies for people aged 5 years and older
-
Aboriginal Medical Services
Free vaccination clinics are also being offered by South Western Sydney Local Health District until 16 April 2026.
