Update: Measles cluster in Perth metropolitan area

10 October 2019

Two new cases of measles have been confirmed in metropolitan Perth in the past two days.

There have now been 19 confirmed measles cases in the Perth metropolitan area since mid-September.

Measles is a serious and highly contagious viral illness spread by tiny droplets released when infected people cough and sneeze. 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.

Every measles case is treated as a public health emergency because of the risk of local spread. This includes 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.

What are the symptoms of measles?

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 3 or 4 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. Measles is contagious for about 4 days before and after the development of the rash.

Anyone who has had a potential exposure to measles, and who develops a fever with these other symptoms should see a doctor.

People who are concerned they may have measles and require medical advice after hours can contact healthdirect on 1800 022 222.

It is important to call ahead when travelling to a clinic or Emergency Department so people with measles can be isolated from infecting other patients and staff.

Have you been fully vaccinated against measles?

People born before 1966 are usually immune to measles because they had the illness as a child. People born during or after 1966 need 2 doses of the measles-containing vaccine to be fully covered, especially if they plan to travel overseas. People aged 53 years or younger in 2019 who have not had the second dose of the vaccine, or if they are not sure, are eligible for a free vaccine from their GP, Aboriginal Medical Service, travel clinic or community health immunisation clinic.

Parents are also 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.
