Two additional cases of measles have been confirmed in Sydney, prompting NSW Health to issue a warning of the increased risk of infection as the highly contagious virus remains in circulation.
Health officials said the two individuals were unknowingly infectious while attending various locations throughout western Sydney, the inner west, and the CBD, with new exposure sites added to the NSW Health website.
They emphasized that the listed venues are not a current risk but urged anyone who attended during the nominated times to be vigilant for symptoms in the coming days.
One of the new cases is thought to have acquired the infection locally after attending an exposure venue earlier this month at the same time as another confirmed case.
The second case recently returned from South East Asia, where several countries are experiencing outbreaks of measles.
New cases have pushed the total number of confirmed cases in the state to 21 since 1st January 2026, with the overall risk being increased.
It is important to note that the symptoms may take up to 18 days to appear after exposure, hence the need for anyone who may have been exposed to monitor their health for more than two weeks.

These may be followed by a rash of red, blotchy skin usually starting on the head and then spreading to the body.
NSW Health also advised that people with a rash following early symptoms of measles should consider that they have measles, even if they have not been to a listed exposure site.
The department again emphasized the importance of vaccination as the best protection, saying that the MMR vaccine is safe and effective and recommended for children at 12 and 18 months of age.
