What is it?

Measles is a highly contagious viral illness.

What to look for

Infection usually begins with 2-4 days of fever, malaise, cough, runny nose and conjunctivivits.

A macropapular rash then develops, often beginning on the face before becoming more generalised.

Complications of disease include pneumonia, encephalitis, brain damage, subacute sclerosing panencephalitis (SSPE) and death.

Measles infections during pregnancy can result in miscarriage and prematurity.

How is it transmitted?

It is highly infective and spread by coughing and sneezing.


The measles vaccines (measles-mumps-rubella or measles-mumps-rubella-varicella) can protect against disease. For those born after 1966, 2 doses are required for lifelong protection. Currently on the National Immunisation Program this is given at 12 months of age (MMR) and 18 months of age (MMRV).

Post-exposure prophylaxis

If a non-immune individual is exposed to measles, immunisation with MMR or MMRV is recommended to occur within 72 hours of exposure in order to reduce the likelihood of infection (provided immunisation is not a contraindication).  

In some instances, administration of Normal Human Immunoglobulin (NHIG) may be indicated [refer to resources].
