A child is one-of-the-six people who've contracted measles after coming into contact with an infected overseas traveller in Victoria this month.
The tourist from Vietnam attended family events in Mornington and St Kilda on May 4 and 5 before visiting Moonee Ponds, North Melbourne, Coburg, Mount Waverley.
More than 30 babies and toddlers who had contact with the child - who was too young to be vaccinated - at a childcare facility were given antibodies on Wednesday to prevent them developing the disease, acting Chief Health Officer Angie Bone said on Wednesday.
A seventh person has also been diagnosed with measles this week and is linked to another overseas traveller who visited in April.
