What is measles?

is a very contagious illness caused by a virus. It can make you very unwell and cause serious complications.

Measles is uncommon in Australia due to a successful measles vaccination program.

Sometimes measles outbreaks still happen, when travellers become infected while overseas and bring measles back to Australia. Measles is most often seen in people who aren’t immunised. This includes babies who are too young to be vaccinated and people who are unwell or allergic to the vaccine. These people can be protected if enough people in the community are vaccinated to stop the virus spreading. This is called ‘herd immunity’.

Measles in Australia

There is a concern that measles infection is rising in Australia. This is partly because fewer children have been vaccinated since the start of the pandemic. Also, some parents choose not to vaccinate their children.

In some parts of Australia, not enough children are getting vaccinated to reach herd immunity levels. This means a measles outbreak could happen.

The rash can last up to one week.

Symptoms start about 10 to 14 days after being in contact with an infected person.

How do babies and children catch measles?

Measles is a very contagious infection. Up to 9 out of 10 unvaccinated people who come into contact with someone with measles will get sick.
