Measles is a highly contagious viral infection 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 rash classically appears 4 days after prodrome onset. The illness is characterised by cough, coryza, conjunctivitis, a descending morbilliform rash, and fever present at the time of rash onset. The infectious period is from 24 hours prior to onset of the prodrome until 4 days after the onset of the rash.

Doctors should:

  • Offer post exposure prophylaxis (state funded) to non-immune contacts who have been at exposure sites listed above as per Measles CDNA National Guidelines for Public Health Units.
  • Notify urgently any patient with suspected measles to the CDCB on 1300 232 272 (24 hours/7 days). Do not wait for laboratory confirmation.
  • At the time of consultation, take a throat swab in viral transport media (preferred specimen) and urine in a yellow top container both for measles PCR; and measles serology and arrange urgent laboratory testing through SA Pathology. Do not send the patient to a laboratory collection centre.
  • Ensure suspected cases do not use the waiting room, and leave the consultation room vacant for at least 30 minutes after use.
  • Ensure the patient is only seen by practice staff with immunity to measles; wear a correctly fitted particulate filter respirator (i.e. P2/N95) and eye protection.
  • Isolate suspected and confirmed measles cases and exclude from child-care/ school/ workplace for 4 days after rash appearance.

Offer measles vaccine (unless contraindicated) to all potentially susceptible persons who attend your practice. See Australian Immunisation Handbook. Vaccine supply is currently limited in the private market. State funded vaccination is available for eligible groups, refer to South Australia (SA) Funded Measles Vaccination Program | SA Health.
