Measles warning for Perth

21 December 2016

As Western Australians prepare for Christmas holidays, the Department of Health is warning families to ensure their immunisations are up to date following a spike in measles cases caused by local transmission.

Red blotchy measles rash

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

Measles is contagious for about four days before and after the development of the rash. Children and adults who have been inadvertently exposed are at risk of developing measles if they are not immune.

A person is considered immune to measles if they have previously received two doses of a measles vaccine or were born before 1966.

If you or someone you know develops a fever with other symptoms including a cough, runny nose, sore red eyes and a rash within two to three weeks of potential exposure to someone with measles, the infected person should remain isolated from others and arrange to see their family GP.

It is very important to call ahead and advise the medical facility of the possibility of measles so that arrangements can be made to keep other patients and staff away to prevent spreading the virus to others.

Early symptoms of measles include a fever, cough, runny nose and sore eyes, followed by a red blotchy rash about three days later. The rash usually starts on the face and spreads to the rest of the body. Measles infections can be especially severe in infants and people with poor immune systems.

Naturally occurring measles has been eliminated from WA for about 20 years but occasional cases and small outbreaks usually associated with tourists or WA residents who are infected overseas, still occur.

The measles vaccination is safe and highly effective, however children who are too young to receive the vaccination can still be protected from measles if their family members are fully vaccinated and they stay away from people who are not vaccinated.

People born during or after 1966 should make sure they have had two doses of a measles vaccine at some stage in their life, especially before travelling overseas. If a person is unsure if they have been vaccinated in the past, it does not hurt to have another dose. 

Complications following measles can be serious and include ear infections and pneumonia in about 10 per cent of cases. Around 40 per cent of cases require hospitalisation and about one person in every 1,000 will develop encephalitis, an inflammation of the brain.
