Measles advisory for Perth Metropolitan Area

Western Australians are being asked to be alert to the risk of measles following a confirmed measles illness in a person who travelled on public transport and visited multiple venues in the Perth metropolitan area earlier this week.

Children and adults who have been inadvertently exposed are at risk of developing measles if they are not already immune. Individuals should remain vigilant for the onset of measles symptoms for the next three weeks if they are not immune to measles and were present at any of the following:

Secret Harbour:

  • Sunday 27 January, at Woolworths on Secret Harbour Blvd between 8am and 4pm

Crawley:

  • Tuesday 29 January, at the Reid Library of the University of Western Australia between 8am – 5:45pm

Bentley:

  • Wednesday 30 January, at the Robertson Library of Curtin University between 11:15am – 2:15pm

On Transperth buses (950, 100 and 101) and Mandurah train:

  • Tuesday 29 January, train from Aubin Grove to Perth between 07:15 - 8:10am, and train from Perth to Mandurah between 5:45 - 6:40pm
  • Tuesday 29 January, bus 950 from Elizabeth Quay to QEII Medical Centre between 7:40 - 8:40am, and from UWA to Morley between 5:20pm - 6:30pm
  • Wednesday 30 January, on train from Aubin Grove to Perth between 10:25 - 11:15am, and from Canning Bridge to Mandurah between 2:20-3:15pm
  • Wednesday 30 January, on bus 100 between Canning Bridge and Cannington between 10:50-11:40am, and bus 101 from Curtin University to Canning Bridge between 2-2:50pm.

There is no current risk of acquiring measles from visiting one of these venues or riding on public transport in Perth as the potential exposure to measles occurred only on the dates and times specified.

Senior Medical Advisor in Communicable Diseases, Professor Paul Effler said “Measles virus survives less than two hours in the air or on objects and surfaces and is inactivated rapidly in the presence of sunlight or heat.  It is generally considered safe for non-immune individuals to enter a room 30 minutes after a measles case has left the area.”

Persons born prior to 1966 are usually immune to measles because they had the illness as a child. People born during or after 1966 are requested to check that they have had two documented doses of a measles vaccine at some stage in their life, especially if they plan to travel overseas. If they are not sure if they have had two doses of measles vaccine, they should see their doctor for a vaccination before going abroad.

Parents are urged to make sure their children receive their measles vaccinations on schedule. Measles vaccine is currently given to children at 12 and 18 months of age.

With high vaccination coverage, naturally occurring measles has been eliminated from WA for around 20 years, but occasional cases and small outbreaks occur, usually sparked by residents or visitors who were infected overseas.

Public health staff have provided information to people who were exposed to the most recent case where they were known, but it was not possible to identify and specifically warn people who were in public places.

“Measles is a serious and highly contagious viral illness spread by tiny droplets released when infected people cough and sneeze. Every measles case is treated as a public health emergency because of the risk of local spread – including to those most vulnerable to infection, such as infants too young to be vaccinated, those with compromised immune systems and pregnant women who are not already immune through vaccination or previous infection,” Professor Effler said.

People with measles typically develop symptoms approximately 10 days after being exposed to the virus, but this can vary from 7 to 18 days. Early symptoms include fever, cough, runny nose and sore eyes, followed by a red blotchy rash three or four days later. The rash usually starts on the face and spreads to the rest of the body.

“Anyone who has had a potential exposure to measles, and who develops a fever with these other symptoms should see a doctor. It is important to call ahead of travelling to a clinic or Emergency Department so that they can be isolated from infecting other patients and staff when they arrive,” he said.

Complications following measles can be serious and include ear infections and pneumonia in about 10 per cent of cases. Around 30 per cent of cases require a hospital admission and about one person in every 1,000 will develop encephalitis, inflammation of the brain.
