Symptoms

The illness is characterised by:

  • cough
  • coryza
  • conjunctivitis
  • a descending morbilliform rash
  • fever present at the time of rash onset.

Transmission, incubation and infectious period

Measles is transmitted via respiratory aerosols that remain a risk to others for up to 30 minutes after the person has left the area. 

The incubation period is about 10 days (range 7 to 18 days) to the onset of prodromal symptoms and about 14 days to rash appearance.

The infectious period is from 4 days before to 4 days after the appearance of the rash.

Suspected patients

Doctors with patients suspected of having measles are asked to:

  • Notify urgently any patient with suspected measles to the CDCB on 1300 232 272 (24 hours/7 days). Do not wait for laboratory confirmation.
  • Arrange urgent laboratory testing through SA Pathology. Take throat swabs in viral transport medium for measles PCR (preferred specimen) and urine for measles PCR (yellow top container).
  • Isolate suspected and confirmed measles cases and exclude from child-care/ school/ workplace for at least 4 days after rash appearance.
  • Ensure all household and other contacts are protected against measles as indicated in the Australian Immunisation Handbook.
  • Minimise transmission.

Ways to minimise transmission

Minimise transmission of measles:

  • Examine patients suspected of having measles in their own homes wherever possible.
  • Ensure the patient is only seen by practice staff who have confirmed immunity to measles.
  • Ensure suspected cases do not use the waiting room, and conduct the consultation in a room that can be left vacant for at least 30 minutes afterwards.
  • Treat all people who attend the rooms at the same time as and up to 30 minutes after the infectious patient as contacts.

Measles vaccination

  • Two doses of a measles containing vaccine are highly effective at preventing measles. Offer measles vaccine (unless contraindicated, for example in pregnant women or immunosuppression) to all potentially susceptible persons who attend your practice.
  • Measles vaccine should be considered in susceptible persons prior to overseas travel.
  • Many people born in the late 1960s to mid-1980s may have only received one measles vaccine.
