A new case of measles has been reported in Victoria with the patient who was infectious in the Cranbourne area during late December.

The exposure sites include Cranbourne Bunnings on December 27 (7.20pm - 8.20pm) and Chemist Warehouse in Cranbourne North on December 28 between 11.30am and 12.40pm.

This is in addition to three recent Victorian measles cases linked to travel to South-East Asia.

There has been an increase in notified cases of measles in returned travellers across Australia in recent weeks. Growing outbreaks have been reported internationally including in Vietnam and Thailand.

The Victorian Chief Health Officer has issued an alert and said anyone who had been to any of the listed exposure sights during the specified times should monitor for symptoms of measles.

Symptoms can develop between seven to 18 days after exposure.

Measles is a highly infectious viral illness that can spread from person-to-person and potentially lead to serious health complications.

Anyone who develops symptoms of measles should seek medical care. Wear a mask and call ahead to make sure you can be isolated from others.

Anyone planning overseas travel should make sure they have received appropriate travel vaccinations, including MMR vaccine. This is especially important for anyone planning on travelling to South-East Asia.

The measles-mumps-rubella (MMR) vaccine provides safe and effective protection against measles and is available for free.
