Western Australians are being asked to be alert to the risk of measles following the reporting of a confirmed case of the viral illness in a returned traveller.
Infected while overseas, the person visited a number of Perth venues while they were infectious between Friday 7 April and Thursday 13 April.
The Health Department’s Director of Communicable Diseases Dr Paul Armstrong said public health staff were contacting people who were exposed, where they are known.
“We wish to advise the person also caught a number of public transport routes while infectious and it is not possible for us to trace everyone who was travelling at those times, to warn them about the potential risk.”
All dates, times and routes travelled by the person while infectious are listed below.
There is no current or ongoing risk of acquiring measles from taking these public transport routes – potential exposure occurred only on the dates and times specified.
“Measles is a serious and highly contagious viral illness spread by tiny droplets released when infected people cough and sneeze,” Dr Armstrong warned.
“Children and adults without measles immunity who were inadvertently exposed during this period are at risk of being infected and should be vigilant for the onset of symptoms.”
People with measles typically develop symptoms around 10 days after being exposed to the virus, but this can vary from seven 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 early symptoms should see a doctor,” Dr Armstrong said.
“It is important to call ahead before travelling to a clinic or Emergency Department so that they can isolate you from infecting other patients and staff when you arrive.”
Every measles case is treated as a public health emergency because of the risk of local spread and the potentially severe nature of the disease.
Those most vulnerable to infection include infants too young to be vaccinated, those with compromised immune systems and pregnant women, who are not already immune through vaccination or previous infection.
Naturally occurring measles has been eliminated from Australia for around 25 years thanks to high vaccination coverage. Small outbreaks sometimes occur, sparked by residents or visitors who were infected overseas.
Numerous countries are currently experiencing outbreaks of measles and people travelling to these countries are at risk if they do not have immunity to the illness.
People born in or after 1966 should make sure they have had two documented doses of a measles vaccine at some stage in their life. If unsure, they should see their doctor for a vaccination before going abroad.
People born before 1966 are usually immune to measles because they had the illness as a child.
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.
People who are concerned they may have measles and require medical advice after hours can contact healthdirect on 1800 022 222.
