SA Health has issued a health alert after confirming a case of measles in a child who was exposed overseas, prompting warnings for anyone who visited several Adelaide Hills locations earlier this month.
The alert, released on Sunday, outlines a series of public exposure sites across Woodside, Mount Barker and Hahndorf between 8 and 14 November 2025. Measles is one of the most contagious viral illnesses, and SA Health says quick awareness is key to preventing further spread.
The alert was issued after SA Health was notified of a case of measles in a child who was exposed overseas. Measles is a serious and highly contagious infectious disease.
SA Health stresses, “Anyone who isn’t fully immunised, and particularly those who were in the locations at the times listed, should be alert for symptoms over the next few weeks and see a doctor if they become ill.”
Exposure locations
SA Health has identified the following sites:
- One Healthcare Woodside
• Friday 14 November, 1:00pm – 2:30pm
• Wednesday 12 November, 1:00pm – 2:30pm - Mount Barker District Soldiers’ Memorial Hospital
• Friday 14 November, 2:35pm – 10:00pm - Woodside Primary School
• Monday 10 November, 8:30am – 4:00pm - Dance Fusion, Hahndorf

• Sunday 9 November, 2:30pm – 7:00pm - Bunnings Mount Barker
• Saturday 8 November, 3:30pm – 4:50pm
SA Health is asking the community—particularly families with young children, and anyone who may be unsure about their vaccination status—to remain vigilant. Measles symptoms usually appear around 10 days after exposure but can take as long as 18 days to develop.
Early symptoms include fever, cough, runny nose and sore eyes, which can often be mistaken for a common cold or viral infection. These are followed by a recognisable blotchy rash that typically starts on the head and spreads downward.
The department reminds anyone who begins to feel unwell and suspects they may have measles to avoid attending GP clinics or emergency departments without calling ahead. If you believe you have measles symptoms, contact your doctor before you visit so precautions can be taken to avoid spreading the infection to others.”
Measles can lead to serious complications, particularly in young children and those with weakened immune systems. Vaccination through the MMR (measles, mumps, rubella) vaccine remains the most effective protection, and SA Health encourages anyone unsure of their immunisation history to check their records or speak with their healthcare provider.
